Dual power supply
Board contains switching power
supply that creates stable voltage
and current levels necessary for
powering each part of the board.
Power supply section contains two power
regulators: MC34063A, which generates VCC-
5V, and MC33269DT3.3 which creates VCC-3.3V
power supply. Board can be powered in three different
ways: with USB power supply (CN1), using external adapters
via adapter connector (CN25) or additional screw terminals
(CN24). External adapter voltage levels must be in range of 9-32V DC
and 7-23V AC. Use jumper J8 to specify which power source you are using,
and jumper J16 to specify whether you are using 5V or 3.3V power supply. Upon
providing the power using either external adapter, or USB power source, you can turn
on power supply by using SWITCH 1 (Figure 3-1). Power LED (Green ON) will indicate the
presence of power supply.

dual power supply and smart on-board mikroProg, board is capable of programming
and debugging 14 different microcontrollers from dsPIC30F® family.
There are two DIP40, three DIP28 and one DIP18 socket for dsPIC30® microcontrollers
provided on the board. Which of these sockets you will use depends solely on the
pinout of the microcontroller in use. The EasyPIC v7 for dsPIC30® development
system comes with the dsPIC30F4013 microcontroller in a DIP40 package (pinout
corresponds to DIP40B socket). In order for microcontrollers to have a stable operation,
we provided decoupling capacitive filters on every board socket, Figure 4-1.

Which socket to use?
Supported microcontrollers come in different DIP packages (DIP40,
DIP28 and DIP18) and with different pinout. That is why you need to put
chosen microcontroller in appropriate socket. Here is the list of supported
microcontrollers with DIP sockets:

Using crystal oscillators
If you want to use microcontrollers in DIP28A, DIP28B, DIP28C and DIP18
packages, it is necessary to put quartz crystal into socket X2 (OSC2). The value of
the crystal depends on the maximum clock frequency allowed and your application.
You can always exchange the default 10MHz crystal with another one.
Only one microcontroller may be plugged into the development board at the same time.
Before you plug the microcontroller into the
appropriate socket, make sure that the power
supply is turned off. Images above show how to
correctly plug a microcontroller. First make sure that
a half circular cut in the microcontroller DIP packaging
matches the cut in the DIP socket. Place both ends of
the microcontroller into the socket as shown in Figure
4-3. Then put the microcontroller slowly down until
all the pins match the socket as shown in Figure 4-4.
Check again if everything is placed correctly and press
the microcontroller until it is completely plugged into
the socket as shown in Figure 4-5.
Figure 4-6: RC15 as I/O pin
(when using internal oscillator)
Figure 4-3: Place both ends of microcontroller on
the socket so the pins are aligned correctly
Figure 4-4: with both fingers, evenly distribute
the force and press the chip into the socket.

IMPORTANT:
PIC microcontrollers normally use a quartz crystal for the purpose of providing
clock frequency. The EasyPIC v7 for dsPIC30® provides two sockets for
quartz-crystal. Microcontrollers in DIP40A and DIP40B packages use socket
X1 (OSC1) for quartz-crystal.

On-board programmer
What is mikroProg?
How do I start?
programming
mikroProg is a fast USB 2.0 programmer with mikroICD hardware In-Circuit
Debugger. Smart engineering allows mikroProg to support all dsPIC30®
DIP microcontrollers from Microchip® in a single programmer. Outstanding
performance and easy operation are among it's top features.
In order to start using mikroProg and program your microcontroller, you just
have to follow two simple steps:
1. Install the necessary software
- Install USB drivers
- Install mikroProg Suite for PIC® software
2. Power up the board, and you are ready to go.
- Plug in the programmer USB cable
- LINK LED should light up.
DIP40B DIP28CDIP40A
DIP28A
DIP28B
Why so many LEDs?
Three LEDs indicate specific programmer operation. Link LED lights
up when USB link is established with your PC, Active LED lights up
when programmer is active. Data is on when data is being transferred
between the programmer and PC software (compiler or mikroProg
Suite for PIC®).
Socket selection
DIP18
IMPORTANT - Programming/Debugging
mode raises MCU voltage to 5V!
When on-board mikroProg programmer is in programming/debugging
mode, it automatically raises the MCU voltage to 5V regardless of the power
supply selection (jumper J16). Note that all external peripherals that can
only work on 3.3V must be removed from the board when programming/
debugging is in progress, otherwise they can be permanently damaged.
When programming/debugging is not in progress (execute mode or release
mode) you can connect both 3.3V or 5V peripherals to the board depending
on the position of jumper J16.

mikroICD - In Circuit Debugger
What is Debugging?
Every developer comes to a point where he has to monitor the
code execution in order to find errors in the code, or simply
to see if everything is going as planed. This hunt for bugs, or
errors in the code is called debugging. There are two ways
to do this: one is the software simulation, which enables
you to simulate what is supposed to be happening on the
microcontroller as your code lines are executed, and the other,
most reliable one, is monitoring the code execution on the
chip itself. And this latter one is called In-Circuit debugging.
"In-Circuit" means that it is the real deal - code executes right
on the target device.
What is mikroICD?
The on-board mikroProg programmer supports mikroICD - a
highly effective tool for a Real-Time debugging on hardware
level. The mikroICD debugger enables you to execute your
program on the host PIC microcontroller and view variable
values, Special Function Registers (SFR), RAM, CODE and
EEPROM memory along with the mikroICD code execution
on hardware. Whether you are a beginner, or a professional,
this powerful tool, with intuitive interface and convenient
set of commands will enable you to track down bugs quickly.
mikroICD is one of the fastest, and most reliable debugging
tools on the market.
Supported Compilers
All MikroElektronika compilers, mikroC, mikroBasic and
mikroPascal for PIC®, dsPIC® and PIC32® natively support
mikroICD. Specialized mikroICD DLL module allows compilers
to exploit the full potential of fast hardware debugging.
Along with compilers, make sure to install the appropriate
programmer drivers and mikroProg Suite for PIC®
programming software, as described on pages 12 and 13.
When you build your project for debugging, and program the
microcontroller with this HEX file, you can start the debugger
using [F9] command. Compiler will change layout to debugging
view, and a blue line will mark where code execution is currently
paused. Use debugging toolbar in the Watch Window to
guide the program execution, and stop anytime. Add the desired
variables to Watch Window and monitor their values. Complete
guide to using mikroICD with your compiler is provided with the
EasyPIC v7 for dsPIC30® package.
How do I use the debugger?

UART via RS-232
communication
The UART (universal asynchronous
receiver/transmitter) is one of the most
common ways of exchanging data between
the MCU and peripheral components. It is
a serial protocol with separate transmit and
receive lines, and can be used for full-duplex
communication. Both sides must be initialized with
the same baud rate, otherwise the data will not be
received correctly.
RS-232 serial communication is performed through a
9-pin SUB-D connector and the microcontroller UART
module. In order to enable this communication, it
is necessary to establish a connection between
RX and TX lines on SUB-D connector and the
same pins on the target microcontroller using
DIP switches. Since RS-232 communication
voltage levels are different than
microcontroller logic levels, it is
necessary to use a RS-232
Transceiver circuit, such as
MAX3232 as shown
on Figure 6-1.

Enabling RS-232
In order to enable RS-232
communication, you must set J20
and J21 jumpers in the RS-232
position, and enable desired RX
and TX lines via SW8 and SW9
DIP switches. For example, if you
want to enable RS-232 connection
on UART1 module of the default
dsPIC30F4013 chip, you should
enable SW8.1 (RF2) and SW9.1
(RF3) lines.

UART via USB
Modern PC computers, laptops and notebooks
are no longer equipped with RS-232 connectors
and UART controllers. They are nowadays replaced
with USB connectors and USB controllers. Still, certain
technology enables UART communication to be done over USB
connection. Controllers such as FT232RL from FTDI® convert UART
signals to the appropriate USB standard. In order to use USB-UART
module on EasyPIC v7 for dsPIC30®, you must first install FTDI drivers on
your computer. Drivers can be found on the link below:
USB-UART communication is being done through a FT232RL
controller, USB connector (CN2), and microcontroller UART module.
To establish this connection, you must put J20 and J21 jumpers
in the USB-UART position, and connect RX and TX lines
of the microcontroller to the appropriate input
and output pins of the FT232RL. This
selection is done using DIP switches
SW8 and SW9.

Enabling USB-UART
In order to enable USB-UART
communication, you must set J20
and J21 jumpers in the USB-UART
position, and enable desired RX
and TX lines via SW8 and SW9 DIP
switches. For example, if you want
to enable USB-UART connection
on UART1 module of the default
dsPIC30F4013 chip, you should
enable SW8.1 (RF2) and SW9.1
(RF3) lines.

communication
Controller Area Network (CAN or CAN bus) is a vehicle bus standard designed to allow microcontrollers
and devices to communicate with each other within a vehicle without a host computer. CAN is a
message-based protocol, designed specifically for automotive applications but now also used in other
areas such as industrial automation and medical equipment. EasyPIC v7 for dsPIC30® is equipped with high-
speed MCP2551 CAN Transceiver and a pair of screw terminals which provide microcontrollers with integrated
CAN controller with the necessary physical interface for CAN communication. Make sure to correctly connect negative
and positive differential communication lines before using this module.

mikroBUS sockets
mikroBUS pinout explained
Easier connectivity and simple configuration
are imperative in modern electronic devices.
Success of the USB standard comes from it’s
simplicity of usage and high and reliable data
transfer rates. As we in MikroElektronika see it,
Plug-and-Play devices with minimum settings
are the future in embedded world too. This is
why our engineers have come up with a simple,
but brilliant pinout with lines that most of
today’s accessory boards require, which almost
completely eliminates the need of additional
hardware settings. We called this new standard
the mikroBUS. EasyPIC v7 for dsPIC30®
supports mikroBUS with two on-board
sockets. As you can see, there are no additional
DIP switches, or jumper selections. Everything
is already routed to the most appropriate pins
of the microcontroller sockets.
mikroBUS host connector
Each mikroBUS host connector consists of two
1x8 female headers containing pins that are
most likely to be used in the target accessory
board. There are three groups of communication
pins: SPI, UART and I2C communication. There
are also single pins for PWM, Interrupt,
Analog input, Reset and Chip Select. Pinout
contains two power groups: +5V and GND on
one header and +3.3V and GND on the other
1x8 header.

One of the most distinctive features of EasyPIC v7
for dsPIC30® are it’s Input/Output PORT groups. They
add so much to the connectivity potential of the board.
Everything is grouped together
PORT headers, PORT buttons and PORT LEDs are next to each other, and
grouped together. It makes development easier, and the entire EasyPIC v7 for
dsPIC30® cleaner and well organized. We have also provided an additional PORT
headers on the left side of the board, so you can access any pin you want from both
sides of the board.
Tri-state pull-up/down DIP switches
Tri-state DIP switches, like SW1 on Figure 10-2, are used
to enable 4K7 pull-up or pull-down resistor on any desired port
pin. Each of those switches has three states:
1. middle position disables both
pull-up and pull-down feature from
the PORT pin
2. up position connects the resistor
in pull-up state to the selected pin
3. down position connects the
resistor in pull-down state to the
selected PORT pin.

The logic state of
all microcontroller
digital inputs may
be changed using
push buttons.
Tri-state DIP
switch SW7 is
available for selecting which logic state will be applied
to corresponding MCU pin when button is pressed, for
each I/O port separately. If you, for example, place
SW7.1 in VCC position, then pressing any of push
buttons in PORTB I/O group will apply logic one to
the appropriate microcontroller pin. The same goes
for GND. If DIP switch is in the middle position neither
of two logic states will be applied to the appropriate
microcontroller pin. You can disable pin protection
220ohm resistors by placing jumpers J5 and J6, which
will connect your push buttons directly to VCC or GND.
Be aware that doing so you may accidentally damage
MCU in case of wrong usage.
Headers Buttons LEDs
connectivity
Figure 10-5: IDC10 male headers enable easy
connection with MikroElektronika accessory boards
With enhanced connectivity as one of the key features
of EasyPIC v7 for dsPIC30®, we have provided two
connection headers for each PORT. I/O PORT group
contains one male IDC10 2x5 header (like CN3 on Figure
10-4) and one 1x10 row of connection pads (like CN5
on Figure 10-4). There is one more IDC10 header
available on the left side of the board, next to the section
with displays. These headers are all compatible with all
MikroElektronika accessory boards, and enable simple
connection.
LED (Light-Emitting
Diode) is a highly
efficient electronic
light source. When
connecting LEDs,
it is necessary to
place a current
limiting resistor in
series so that LEDs
are provided with
the current value specified by the manufacturer. The
current varies from 0.2mA to 20mA, depending on the
type of the LED and the manufacturer. The EasyPIC v7
for dsPIC30® board uses low-current LEDs with typical
current consumption of 0.2mA or 0.3mA. Board contains
42 LEDs which can be used
for visual indication of the
logic state on PORT pins. An
active LED indicates that a
logic high (1) is present on
the pin. In order to enable
PORT LEDs, it is necessary
to enable the corresponding
DIP switch on SW10 (Figure
10-7). Figure 10-7: SW10.1

switches are used to
enable PORT LEDs

Liquid Crystal Displays or LCDs are cheap and
popular way of representing information to the
end user of some electronic device. Character
LCDs can be used to represent standard and
custom characters in the predefined number
of fields. EasyPIC v7 for dsPIC30® provides the
connector and the necessary interface for supporting
2x16 character LCDs in 4-bit mode. This type of
display has two rows consisted of 16 character fields.
Each field is a 7x5 pixel matrix. Communication with the
display module is done through CN7 display connector. Board
is fitted with uniquely designed plastic display distancer, which
allows the LCD module to perfectly and firmly fit into place.

We have allowed LCD back light to be enabled in two different ways:
1. It can be turned on with full brightness using SW10.8 switch.
2. Brightness level can be determined with PWM signal from the
microcontroller, allowing you to write custom back light controlling
software. This back light mode is enabled with SW10.7 switch.

Graphical Liquid Crystal Displays, or GLCDs are used to display
monochromatic graphical content, such as text, images, human-
machine interfaces and other content. EasyPIC v7 for dsPIC30®
provides the connector and necessary interface for supporting
GLCD with resolution of 128x64 pixels, driven by the KS108 or
compatible display controller. Communication with the display
module is done through CN16 display connector. Board is fitted
with uniquely designed plastic display distancer, which allows
the GLCD module to perfectly and firmly fit into place.
Display connector is routed to RF0, RF1, RF4, RF5
(control lines) and to RB0-RB3, RD0-RD3 (data
lines) of the microcontroller sockets. Since the
same ports are used by 2x16 character LCD display,
you cannot use both displays simultaneously. You
can control the display contrast using dedicated
potentiometer P2. Full brightness display back light can
be enabled with SW10.8 switch, and PWM-driven back
light with SW10.7 switch.

Touch panel controller
Enabling Touch panel
Correctly placing the touch panel cable into the connector
Touch panel is a glass panel whose surface is covered
with two layers of resistive material. When the screen
is pressed, the outer layer is pushed onto the inner layer
and appropriate controllers can measure that pressure
and pinpoint its location. This is how touch panels can
be used as an input devices. EasyPIC v7 for dsPIC30®
is equipped with touch panel controller and connector for
4-wire resistive touch panels. It can very accurately
register pressure at a specific point, representing the touch
coordinates in the form of analog voltages, which can then
be easily converted to X and Y values. Touch panel comes as
a part of display.

One seven segment digit consist of
7+1 LEDs which are arranged in a
specific formation which can be used
to represent digits from 0 to 9 and
even some letters. One additional LED
is used for marking the decimal dot, in
case you want to write a decimal point
in the desired segment. EasyPIC v7 for
dsPIC30® contains four of these digits
put together to form 4-digit 7-segment
display. Driving such a display is done
using multiplexing techniques. Data
lines are shared between segments, and
therefore the same segment LEDs in
each digit are connected in parallel. Each
digit has it’s unique digit select line,
which is used to enable the digit
to which the data is currently being
sent. By multiplexing data through all
four segments fast enough, you create
an illusion that all four segments are
in operation simultaneously. This is
possible because human eye has a
slower reaction time than the mention
changes.
This way you can represent numbers in
decimal or hexadecimal form. Eight data
lines that are common for all the digits
are connected to PORTB, and digit select
lines are connected to RC13, RC14, RF4
and RF5 lines on the microcontroller
sockets.
To enable digit select lines for the 4-digit
7-segment display you have to turn on
SW11.1, SW11.2, SW11.3 and SW11.4
switches. Digit select lines are connected
to RC13, RC14, RF4 and RF5 pins on the
microcontroller sockets, while data lines are
connected to RB0 – RB7 pins. Make sure
to disconnect other peripherals from the
interface lines in order not to interfere with
signal/data integrity.

DS1820 - Digital
Temperature Sensor
DS1820 is a digital temperature
sensor that uses 1-wire®
interface for it’s operation. It is
capable of measuring temperatures
within the range of -55 to 128°C,
and provides ±0.5°C accuracy for
temperatures within the range of -10 to
85°C. It requires 3V to 5.5V power supply
for stable operation. It takes maximum
of 750ms for the DS1820 to calculate
temperature with 9-bit resolution.
1-wire® serial communication enables
data to be transferred over a single
communication line, while the process
itself is under the control of the master
microcontroller. The advantage of
such communication is that only one
microcontroller pin is used. Multiple
sensors can be connected on the same
line. All slave devices by default have
a unique ID code, which enables the
master device to easily identify all
devices sharing the same interface.
Board provides a separate socket (TS1)
for the DS1820. Communication line
with the microcontroller is connected via
jumper J9.
EasyPIC v7 for dsPIC30® enables you to establish 1-wire® communication between
DS1820 and the microcontroller via RA11 or RE0 microcontroller pins. The
selection of either of those two lines is done using J9 jumper. When placing the
sensor in the socket make sure that half-circle on the board’s silkscreen markings
matches the rounded part of the DS1820 sensor. If you accidentally connect the
sensor the other way, it may be permanently damaged. Make sure to disconnect
other peripherals (except 1-wire), LEDs and additional pull-up or pull-down resistors
from the interface lines in order not to interfere with signal/data integrity.

The LM35 is a low-cost precision
integrated-circuit temperature sensor,
whose output voltage is linearly
proportional to the Celsius (Centigrade)
temperature. The LM35 thus has an
advantage over linear temperature
sensors calibrated in ° Kelvin, as the
user is not required to subtract a large
constant voltage from its output to
obtain convenient Centigrade scaling.
It has a linear +10.0 mV/°C scale factor
and less than 60 μA current drain. As it
draws only 60 μA from its supply, it has
very low self-heating, less than 0.1°C
in still air. EasyPIC v7 for dsPIC30®
enables you to get analog readings
from the LM35 sensor in restricted
temperature range from +2ºC to +150ºC.
Board provides a separate
socket (TS2) for the LM35
sensor in TO-92 plastic
packaging. Readings are
done with microcontroller using
single analog input line, which is
selected with jumper J13. Jumper
connects the sensor with either PB8 or
PB10 microcontroller pins.
EasyPIC v7 for dsPIC30® enables you to get analog readings from the LM35

sure that half-circle on the board’s silkscreen markings matches the rounded
part of the LM35 sensor. If you accidentally connect the sensor the other way,
it can be permanently damaged and you might need to replace it with another
one. During the sensor readings make sure that no other device is using the
selected analog line, as that may interfere with the readings.

Digital signals have two discrete states, which
are decoded as high and low, and interpreted
as logic 1 and logic 0. Analog signals, on the
other hand, are continuous, and can have any
value within defined range. A/D converters are
specialized circuits which can convert analog signals
(voltages) into a digital representation, usually in
form of an integer number. The value of this number
is linearly dependent on the input voltage value. Most
microcontrollers nowadays internally have A/D converters
connected to one or more input pins. Some of the most
important parameters of A/D converters are conversion time
and resolution. Conversion time determines how fast can an
analog voltage be represented in form of a digital number. This is an
important parameter if you need fast data acquisition. The other parameter
is resolution. Resolution represents the number of discrete steps that supported
voltage range can be divided into. It determines the sensitivity of the A/D converter.
Resolution is represented in maximum number of bits that resulting number occupies. Most PIC®
microcontrollers have 12-bit resolution, meaning that maximum value of conversion can be represented with 12
bits, which converted to integer is 212=4096. This means that supported voltage range, for example from 0-5V,
can be divided into 4096 discrete steps of about 1.22mV. We gave you the possibility to set microcontroller
voltage reference to 4.096V DC by putting jumper J10 (RBO/VREF+) to 4.096V position, Figure 17-2. This
can be done only when the power supply is 5V (jumper J16 in 5V position). In that case discrete steps are
1mV. When using voltage reference module, make sure to disconnect other peripherals from RB0 pin. EasyPIC
v7 for dsPIC30® provides an interface in form of potentiometer for simulating analog input voltages that can be
routed to any of the 7 supported analog input pins.

EEPROM is short for Electrically Erasable
Programmable Read Only Memory. It is usually
a secondary storage memory in devices containing
data that is retained even if the device looses power
supply. Because of the ability to alter single bytes
of data, EEPROM devices are used to store personal
preference and configuration data in a wide spectrum
of consumer, automotive, telecommunication, medical,
industrial, and PC applications.
EasyPIC v7 for dsPIC30® supports serial EEPROM which
uses I2C communication interface and has 1024 bytes
of available memory. Board contains socket for serial EEPROMs
in DIP8 packaging, so you can easily exchange it with different
memory size EEPROM IC. EEPROM itself supports single byte or 16-byte
(page) write and read operations. Data rate is 400 kHz for both 3.3V and 5V
power supply.
In order to connect I2C EEPROM to the
microcontroller you must place J14 (SCL) and J15
(SDA) jumpers in appropriate position. 1kΩ pull-
up resistors necessary for I2C communication are
already provided on SDA and SCL lines. Prior to
using EEPROM in your application, make sure to
disconnect other peripherals, LEDs and additional
pull-up or pull-down resistors from the interface
lines in order not to interfere with signal/data
integrity. I2C is a multi-master serial single-ended bus that is used to attach low-speed peripherals to computer or
embedded systems. I²C uses only two open-drain lines, Serial Data Line (SDA) and Serial Clock (SCL), pulled
up with resistors. SCL line is driven by a master, while SDA is used as bidirectional line either by master or slave
device. Up to 112 slave devices can be connected to the same bus. Each slave must have a unique address.

Piezo electricity is the charge which
accumulates in certain solid materials in response
to mechanical pressure, but also providing the
charge to the piezoelectric material causes it to
physically deform. One of the most widely used
applications of piezo electricity is the production
of sound generators, called piezo buzzers. Piezo
buzzer is an electric component that comes in
different shapes and sizes, which can be used to create
sound waves when provided with analog electrical signal.
EasyPIC v7 for dsPIC30® comes with piezo buzzer which
can be connected either to RD0 or RA11 microcontroller
pins, which is determined by the position of J12 jumper. Buzzer
is driven by transistor Q6 (Figure 19-1). Microcontrollers can create
sound by generating a PWM (Pulse Width Modulated) signal – a square

In order to use the on-board Piezo Buzzer in
your application, you first have to connect the
transistor driver of piezo buzzer to the appropriate
microcontroller pin. This is done using jumper J12.
You can place the jumper in two positions, thus
connecting the buzzer driver to either RD0 or RA11
microcontroller pin.
Buzzer starts "singing" when you provide
PWM signal from the microcontroller
to the buzzer driver. The pitch of the
sound is determined by the frequency,
and amplitude is determined by the
duty cycle of the PWM signal.

wave signal, which is nothing more than a sequence of logic
zeros and ones. Frequency of the square signal determines the
pitch of the generated sound, and duty cycle of the signal can
be used to increase or decrease the volume in the range from
0% to 100% of the duty cycle. You can generate PWM signal
using hardware capture-compare module, which is usually
available in most microcontrollers, or by writing a custom
software which emulates the desired signal waveform.
Supported sound frequencies
Piezo buzzer’s resonant frequency (where you can expect it's
best performance) is 3.8kHz, but you can also use it to create
sound in the range between 2kHz and 4kHz.
