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!

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 dierent 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).

VCAP jumpers explained
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 lters should
be provided, and connected between specic 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:
VCAP position when using PIC16F724/16F727
VCAP position for PIC18F44J10 and PIC18F45J10
VCAP for PIC18F24J10, PIC18F25J10 PIC18F2XJ50, PIC18F2XJ11
VCAP for PIC16F722, PIC16F723, PIC16F726
IMPORTANT: If you do not place VCAP jumper for the MCUs that need it,
you might experience some instabilities in program execution.
IMPORTANT: When using PIC18F2331 or PIC18F2431 microcontollers it is necessary
to place J20 jumper, in order to route VCC power line to RA5 pin (Figure 4-1)

Using crystal oscillators
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 quartz-
crystal depends on the maximum clock frequency allowed, and your application,
and you can always exchange the default 8MHz 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
o. 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.
Figure 4-6: RA6 and RA7 as I/O pins
(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 ngers, evenly distribute
the force and press the chip into the socket.
Figure 4-5: Properly placed microcontroller will
have equally leveled pins.

IMPORTANT:
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.
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.

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 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.
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. MCLR pin

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 on-
board reset circuit, or
acts just as I/O pin.

mikroICD™- In Circuit Debugger
page 14
What is Debugging?
Every developer comes to a point where he has to monitor the
code execution in order to nd 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 eective 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 le, 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.
How do I use the debugger?

Here is a short overview of which debugging commands are supported in mikroElektronika compilers. You can see what each command does,
and what are their shortcuts when you are in debugging mode. It will give you some general picture of what your debugger can do.

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 baudrate, 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 dierent 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 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.

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 rst 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 denes cables, connectors
and protocols used for communication
and power supply between computers
and other devices. EasyPIC™ v7 contains
USB connector (CN4) which enables
microcontrollers that support USB
communication to establish a connection
with the target host (eg. PC, Laptop, etc).
Selection of communication lines is done
using jumpers J12 or J18, depending on
the target microcontroller.
When communication lines are
routed from the microcontroller to the
USB connector using mentioned jumpers,
they are cut o from the rest of the
board, and cannot be accessed via PORT
headers.

mikroBUS™sockets
mikroBUS™pinout explained
Easier connectivity and simple conguration 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 rst 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
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.
