POWER SUPPLY
The PICPLC16 v7a development system is connected to the power
supply source via the TB1 connector. The power supply voltage
can be either DC or AC. A DC power supply voltage can be in the
range of 9V to 32V, whereas the AC power supply voltage can
range between 7V and 23V. Have in mind that the board cannot
operate without being connected to the power supply source
although it is connected to a PC via the USB cable.
On-board is a very accurate, programmable voltage reference
(VREF) in the range from 0V to 3.3V. VREF is very useful for
many different applications including A/D and D/A converters,
comparators, etc. The programmable voltage output can be
controlled over the CODEGRIP Suite.

HOW TO POWER THE BOARD?
STEP 1 STEP 2
POWER SUPPLY:
Via screw terminal (7V to 23V AC or
9V to 32V DC)
POWER CAPACITY:
Up to 500mA with USB, and
up to 600mA with external
power supply
Figure 3: Powered by wall-adapter
Figure 2: Powered by laboratory PSU
The PICPLC16 v7a development board is powered with
external power supply source. Make sure the power supply
source is connected. Otherwise, the on-board programmer
cannot be enabled.
To power the board using screw
terminals, screw-on the cables
in the screw terminals as shown
on image Figure 2, and turn the
power switch ON.
When the development system
is connected to the power
supply source, it is necessary
to plug in a USB cable into
the on-board USB connector.
Connection between the USB
cable and the development
system makes the on-board
programmer to be connected
to a PC.

WHAT IS CODEGRIP?
WHERE TO START?
CODEGRIP is a unified solution, designed to perform programming and
debugging tasks on a range of different microcontroller devices (MCUs)
based on the Microchip PIC architecture. The USB-C connector offers
improved performance and reliability, compared to traditionally used
USB Type A/B connectors.
PICPLC16 v7a development board is supported by a powerful CODEGRIP
Suite, offering complete control over the development board. It is used
to intelligently manage programming and debugging tasks, and to
configure various other options and settings, providing visual feedback
through its clean and comprehensive Graphical User Interface (GUI).
To better understand how to operate and configure PICPLC16 v7
development board and its integrated CODEGRIP module, check out the
CODEGRIP Suite quick start guide on the www.mikroe.com/picplc16-v7a
In order to start using CODEGRIP and program your
microcontroller, you just have to follow two simple steps:
1. Install the necessary software
∫ Install CODEGRIP Suite 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 transferred between the programmer and
PC software. (Compiler or CODEGRIP).

PICPLC 16 v7a is equipped with RJ-12 connector compatible with
Microchip®ICD2, ICD3, and ICD4 external programmers. You can either
use the on-board CODEGRIP programmer or external programming
tools as long as you use only one of them in the same time. Insert
your ICD programmer cable into connector CN9, as shown in image.

ETHERNET
Ethernet is a popular networking technology for local area networks
(LAN). Systems communicating over Ethernet divide a stream of data
into individual packets, known as frames. Each frame contains source
and destination addresses and error-checking data so that damaged
data can be detected and re-transmitted. This makes the Ethernet
protocol very popular for communication over longer distances or in
noisy environments.
The PICPLC16 v7a features standard RJ-45 Ethernet connector to
establish a connection with a personal computer, network router,
or other Ethernet network device. PIC18F97J60 MCU feature
an embedded Ethernet controller module. This is a complete
connectivity solution, including full implementations of both Media
Access Control (MAC) and Physical Layer (PHY) transceiver modules.

LIN COMMUNICATION
LIN (Local Interconnect Network) is a inexpensive serial network protocol used for communication between components in
vehicles, It effectively supports remote application within a car's network. The LIN Bus is particularly intended for mechatronic
nodes in distributed automotive applications, but is equally suited to industrial applications.
The PICPLC16 v7a utilizes the MCP2003B, it provides a physical
interface to automotive and industrial LIN systems, in accordance to
the LIN Bus Specifications Revision 2.2, SAE J2602 and ISO 17987. It
is short circuit and overtemperature protected by internal circuitry.
MCP2003B communicates with the target board MCU through the
UART interface (RXD, TXD), with additional functionality provided by
the CS and WAKE pins.
COMMUNICATION

ON (up): connects the RG1 pin to the transmit data input
OFF (down): disconnects the RG1 pin from the transmit data input

A four-pole DIP switch (SW16) located in the LIN COMM. section of the board, allow fully independent control of the UART RX and TX lines,
and CS and WAKE lines.

mikroBUS™SOCKETS
The superior connectivity features of the EasyPIC v7a development board
are rounded up with three standardized mikroBUS™host connectors. It is
a considerable upgrade for the board, as it allows interfacing with the vast
amount of Click boards™.
mikroBUS™is the add-on board standard that offers maximum
expandability with the smallest number of pins. More information at www.
mikroe.com/mikrobus
All the mikroBUS™sockets are now redesigned and improved. They
became much sturdier, allowing a better grip of the Click board™. In
addition to added horizontal supports between two 8-pin connectors,
the right lower edge is chamfered at the angle of 45°, the same as the
Click board™, making it seamlessly fit into the mikroBUS™socket. The
new mikroBUS™socket is now a fully-fledged, standardized monolithic
component with all its pins clearly labeled, offering very good grip for the
Click board™, preventing it to flip over or to be placed incorrectly.
mikroBUS™is not made to be only a part of our development boards.
You can freely place mikroBUS™host connectors in your final PCB
designs, as long as you clearly mark them with mikroBUS™logo and
footprint specifications. For more information, logo artwork and

both pull-up and pull-down feature

2. UP POSITION connects the

3. DOWN POSITION connects
the resistor in pull-down state to the

I/O pins of MCU are internally grouped as PORTs. The same grouping concept is kept throughout the development board as
well, offering a clean and organized user interface.

A real-time clock is widely used in alarm devices, industrial controllers, consumer devices etc. An external real-time clock
peripheral module (RTC) in combination with the button cell battery allow continuous tracking of time, even if the main
power supply is OFF. Extremely low power consumption of the RTC peripheral allows these batteries to last very long.

Figure 11: Buzzer view
Real-Time Clock (RTC)
The main features of the built-in real-time clock MCP79411 from
Microchip are:
¬ Providing information on seconds, minutes, hours, days in a week and
dates including correction for a leap year
¬ I2C serial interface
¬ Automatic power-fail detection
¬ Power consumption around 900nA
A buzzer is a simple device capable of reproducing sound. It is driven by
a small pre-biased transistor. The buzzer can be driven by applying a
PWM signal from the MCU at the base of the transistor: the pitch of the
sound depends on the frequency of the PWM signal, while the volume can
be controlled by changing its duty cycle. Since it is very easy to program,
it can be very useful for simple alarms, notifications, and other types of
simple sound signalization.

MODULES
RELAYS AND OPTOCOUPLERS
Industrial devices usually utilize more power than the
microcontroller can provide via its I/O ports. To enable
the microcontroller to be connected to such devices, the
development system is provided with 16 relays by means of
which it is possible to provide up to 250V/16A power supply.
Each relay has one normally-open (W0, W1...) and one normally-
closed (NW0, NW1...) contact. Sixteen relays are divided in four
groups each consisting of four relays. Relays of one group are
connected to one common contact. Accordingly, there are
COMA, COMB, COMC and COMD common contacts.
In addition to relays, the development system also features
optocouplers, the function of which is to galvanically isolate
signals brought to the microcontroller inputs from industrial
devices. Isolated digital inputs are designed specifically as
digital input receivers for programmable logic control (PLC),
motor control and grid applications to interface between
field-side inputs and a host controller. Input voltage is 5V,
and optocouplers are also linked to one common connector
OCVCC.
