To our valued customers
From the day one, we in mikroElektronika gave ourselves the highest possible goals in pursuit of excellence.
That same day, the idea of EasyPIC™ development board was born. And we all grew together with EasyPIC™.
In its each and tiniest piece we had put all of our energy, creativity and sense of what’s best for an engineer.
I’ve personally assembled hundreds of early EasyPIC™ boards myself with my home soldering iron.
Today, we present you the 7th generation of the board, which brings us some exciting new features. We hope
that you will like it as much as we do.
Use it wisely and have fun!

power supply
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, thus making
the board capable of supporting both 5V and 3.3V
microcontrollers. Power supply unit can be powered in
two different ways: with USB power supply, and using external
adapters via adapter connector (CN31) or additional screw terminals
(CN30). External adapter voltage levels must be in range of 9-32V DC or 7-23V
AC. Use jumper J6 to specify which power source you are using, and jumper J5 to specify
whether you are using 5V or 3.3V microcontroller. Upon providing the power using either
external adapter, or USB power source, you can turn the board on using SWITCH 1 (Figure 3-1).

Some PIC16F, PIC18FK and all PIC18FJ microcontrollers have cores that work
on 1.8V-2.5V voltage range, and peripherals that work with 3.3V and 5V
voltages. Internally, those microcontrollers have power regulators, which adjust
the core voltage levels. In order for those devices to have a stable operation of
the core, manufacturer recommends that decoupling capacitive filters should
be provided, and connected between specific microcontroller pins designated
with VCAP and GND. EasyPIC v7 board provides jumpers which are used for this
purpose. Here is list of devices that require jumpers placed in VCAP position:

How to properly place your microcontroller into the DIP socket?
3
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.
Figure 4-5: Properly placed microcontroller will
have equally leveled pins.
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 maches the cut
in the DIP socket. Place one end 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.
IMPORTANT:
Only one microcontroller may be plugged into the development board at the same time.
Using crystal oscillators

Figure 4-6: RA6 and RA7 as I/O pins
(when using internal oscillator)
2
Figure 4-7: RA6 and RA7 connected
to X1 oscillator
PIC microcontrollers normally use a quartz crystal for the purpose of providing
clock frequency. The EasyPIC™ v7 provides two sockets for quartz-crystal.
Microcontrollers in DIP18A, DIP18B, DIP28 and DIP40 packages use socket
X1 (OSC1) for quartz-crystal.
3
Figure 4-8: RA4 and RA5 as I/O pins
(when using internal oscillator)
4
Figure 4-9: RA4 and RA5 connected
to X1 oscillator
If you want to use microcontrollers in DIP8, DIP14 and DIP20 packages, it is
necessary to put quartz crystal into socket X2 (OSC2). The value of the quartzcrystal depends on the maximum clock frequency allowed, and your application,
and you can always exchange the default 8MHz crystal with another one.
IMPORTANT: Microcontrollers which are plugged into socket 10F use their own internal oscillator and are not connected to any of the mentioned quartz-crystal sockets.

programming
On-board programmer
What is mikroProg™?
mikroProg™ is a fast USB 2.0 programmer with mikroICD™ hardware
In-Circuit Debugger. Smart engineering allows mikroProg™ to support
all PIC10, PIC12, PIC16, PIC18, devices in a single programmer! It
supports over 250 microcontrollers from Microchip®. Outstanding
performance and easy operation are among it's top features.
How do I start?
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.
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 transfered
between the programmer and PC software
(compiler or mikroProg Suite™ for PIC®).
NOTE:
page 10
If you use other than the default PIC18F45K22 MCU, you
want to make sure that programmer jumpers are placed
in proper positions for your microcontroller socket.

Before using the programmer,
make sure to set MCLR pin jumpers
J1 and J2, so that MCLR line is
routed to the correct socket for
your microcontroller. If you are
using the default PIC18F45K22,
jumpers are supposed to be set for
DIP40, as shown below.
Jumpers J8 and J9 are
used to select PGC and
PGD programming lines
for your microcontroller.
Make sure to place
jumpers in the proper
position for your socket.
Using jumper J19
you
can
specify
whether RST pin of
your microcontroller is
connected to the onboard reset circuit, or
acts just as I/O pin.

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.
How do I use the debugger?
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 package.

Figure 5-2: mikroICD™ manual
explains debugging thoroughly
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.

mikroICD™ commands
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 baudrate, otherwise the data will not be
received correctly.
In order to enable RS-232
communication, you must set J3
and J4 jumpers in the RS-232
position, and enable desired RX
and TX lines via SW1 and SW2
DIP switches. For example, if you
want to enable RS-232 connection
on UART1 module of the default
PIC18F45K22 chip, you should
enable SW1.1 (RC7) and SW2.1
(RC6) lines.
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.

UART via USB
Modern PC computers, laptops and notebooks are
no longer equpped with RS-232 connectors and
UART controllers. They are nowdays 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, you must first install FTDI drivers on your
computer. Drivers can be found on Product DVD:

USB-UART communication is being done through a
FT232RL controller, USB connector (CN32), and
microcontroller UART module. To establish this connection, you
must put J3 and J4 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 SW1
and SW2.

USB is the acronym for Universal Serial
Bus. This is a very popular industry
standard that defines cables, connectors

and power supply between computers
and other devices. EasyPIC™ v7 contains

mikroBUS sockets
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 briliant 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
is the first development board in the world to
support mikroBUS™ with two on-board sockets.
As you can see, there are no additional DIP
switches, or jumper selections. Everything is
connectivity
™
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.

Input/Output Group
One of the most distinctive features of EasyPIC™ v7
are it’s Input/Output PORT groups. They add so much to
the connectivity potential of the board.
Everything is groupped together
It took us a while to realize that having PORT headers, PORT buttons and
PORT LEDs next to each other, and groupped together, makes development
easier, and the entire EasyPIC™ v7 cleaner and well organized. We have also provided
Figure 10-1: I/O group contains 3 PORT headers, tri-state
an additional PORT headers on the left side of the board, so you can access any pin
pull up/down DIP switch, buttons and LEDs all in one place
you want from both sides of the board. Some PORT pins are directly connected to the
microcontroller, and some that are connected to other on-board modules are enabled via jumpers (for example USB jumpers, J12 and J18).

LEDs
With enhanced connectivity as one of the key features of
EasyPIC v7, we have provided four connection headers
for each PORT. I/O PORT group contains two male IDC10
2x5 headers (like CN10 and CN15 on Figure 10-4). These
headers are all compatible with over 70 mikroElektronika
accessory boards, and enable simple connection. There is
one more IDC10 header available on the left side of the
board, next to the section with displays.
LED (Light-Emitting
Diode) is a highly
efficient electronic
light source. When
connecting LEDs, it is
Microcontroller
neccessary to place
SMD resistor a current limiting
limiting current resistor in series
through the LED so that LEDs are
provided with the
current value specified by the manufacturer. A common
LED diode voltage is approximately 2.5V, while the
current varies from 0.2mA to 20mA, depending on
the type of the LED. The EasyPIC™ v7 board uses
low-current LEDs with typical current consumption of
0.2mA or 0.3mA, depending
of VCC voltage selection.
Board contains 36 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,

enable PORT LEDs
NOTE: Because of it's orientation, header on the left side
of the board is not meant for placing accessory boards
directly. Instead, use wire jumpers or other ways to
establish connection and utilize these pins.
I/O PORT group also contains 1x10 connection pad (like
CN25 on Figure 10-4) which can be used for connecting
mikroElektronika PROTO boards, or custom user boards.
The logic state of all
microcontroller digital
inputs may be changed
using push buttons.
Jumper J17 is available
Figure 10-6: Button press
for selecting which logic
level jumper (J17)
state will be applied to
corresponding MCU pin when button is pressed in any
I/O port group. If you, for example, place J17 in VCC
position, then pressing of any push button in I/O group
will apply logical one to the appropriate microcontroller
pin. The same goes for GND. If the jumper is taken
out, then all push buttons of the associated PORT will
be disconnected from the microcontroller pin. You can
disable pin protection 220ohm resistors by placing
jumper J24, 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.
Reset Button
Figure 10-5: IDC10 male headers enable easy
connection with mikroElektronika accessory boards
In the far upper right section of the
board, there is a RESET button, which
can be used to manually reset the
microcontroller. This button is directly
connected to the MCLR pin.

displays
LCD 2x16 characters
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 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.
IMPORTANT: Make sure to turn off the power supply before placing LCD onto
the board. Otherwise your display can be permanently damaged.

2. Brightness level can be determined with PWM signal from the
microcontroller, allowing you to write custom backlight controling
software. This backlight mode is enabled with SW4.5 switch.
IMPORTANT: In order to use PWM backlight both SW4.5 and SW4.6 switches must be
enabled at the same time.

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
provides the connector and necessary interface for supporting
GLCD with resolution of 128x64 pixels, driven by the KS108
or similar display controller. Communication with the display
module is done through CN6 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 PORTB
(control lines) and PORTD (data lines) of the
microcontroller sockets. Since PORTB is also
used by 2x16 character LCD display, you cannot
use both displays simoutaneously. You can control
the display contrast using dedicated potentiometer
P3. Full brightness display backlight can be enabled
with SW4.5 switch, and PWM-driven backlight with
SW4.6 switch.

Touchpanel controller
Touchpanel 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 touchpanels can be
used as an input devices. EasyPIC™ v7 is equipped with
touchpanel controller and connector for 4-wire resistive
touchpanels. 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. Touchpanel is ment to be mounted onto
the GLCD 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 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

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 transfered 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.
EasyPIC™ v7 provides a separate socket
(TS1) for the DS1820. Communication
line with the microcontroller is selected
with jumper J11.

of those two lines is done using J11 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 accidently connect the sensor the other way, it
may be permanently damaged and you might need to replace it with another one.
During the readings of the sensor, make sure that no other device (except those in
1-wire network) uses the selected line, because it may interfere with the data.

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 enables you to
get analog readings from the LM35
sensor in restricted temperature range
from +2ºC to +150ºC. Board provides a

ADC inputs
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 lineary dependent on the
input voltage value. Most microcontrollers nowdays 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 10-bit resolution, meaning that maximum value of conversion can be
represented with 10 bits, which converted to integer is 210=1024. This means that supported voltage range, for
example from 0-5V, can be devided into 1024 discrete steps of about 4.88mV.
EasyPIC™ v7 provides an interface in form of two potentiometers for simulating analog input voltages that can be routed to
any of the 10 supported analog input pins.

I C EEPROM
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. EEPROMs come with parallel
or serial interface to the master device. 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 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 rates
are dependant of power supply voltage, and go up to 1 MHz with 5V power supply,
and 400 kHz for 3.3V power supply.
Enabling I2C EEPROM
Figure 18-1:
Activate SW4.7 and
SW4.8 switches
to connect
microcontroller
I2C lines to Serial
EEPROM.
In order to connect I2C EEPROM to the
microcontroller you must enable SW4.7 and
SW4.8 switches, as shown on Figure 18-1. 1kΩ
pull-up resistors necessary for I2C communication
are already provided on SDA and SCL lines once
switches are turned on. Prior to using EEPROM
in your application, make sure to disconnect
other peripherials, LEDs and additional pull-up
or pull-down resistors from the RC3 and RC4
communication lines that could interfere with
the data signals and cause data corruption.
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 bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock (SCL), pulled
up with resistors. Data and clock lines are driven with a master device. Up to 112 slave devices can be connected
to the same bus. Each slave must have a unique address.

Piezo Buzzer
Piezoelectricity 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 piezoelectricity 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 comes
with piezo buzzer which can be connected either to RC2 or
RE1 microcontroller pins, which is determined by the position
of J21 jumper. Buzzer is driven by transistor Q8 (Figure 19-1).
Microcontrollers can create sound by generating a PWM (Pulse Width
Modulated) signal – a square 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.

Enabling Piezo Buzzer
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 J21.
You can place the jumper in two positions, thus
connecting the buzzer driver to either RC2 or RE1
microcontroller pin.
