1. Power supply

You can supply power to the board with a Mini-B USB cable

provided in the package. On-board voltage regulators provide

the appropriate voltage levels to each component on the board.

Power LED (GREEN) will indicate the presence of power supply.

You can also power the board using a Li-Polymer battery, via on-

board battery connector. On-board battery charger circuit enables

you to charge the battery over USB connection. LED diode (RED) will indicate when battery is charging. Charging current is

~300mA and charging voltage is 4.2V DC.

Battery power supply

USBpower supply

Figure 1-1: Connecting USB power supply

Figure 1-2: Connecting Li-Polymer battery

Some click boards need more current than the USB connection can supply. For 3.3V clicks, the upper limit is 750 mA; for 5V clicks,

it’s 500 mA. In those cases you would need to use the battery as the power supply, or the vsys pin on the side of the board.

The microcontroller can be programmed in three ways:

3. Programming the microcontroller

You can program the microcontroller with a

bootloader which is preprogrammed by default.

To transfer .hex file from a PC to MCU you need

bootloader software (mikroBootloader USB HID)

which can be downloaded from:

3.1 Programming with mikroBootloader

Figure 3-2: USB HID mikroBootloader window

step 1 – Connecting clicker 2 for PIC18FJ

01

wait for 5 seconds. Your program will run automatically.

The microcontroller can be programmed with external

mikroProg™ for PIC programmer and mikroProg Suite™

for PIC® software. The external programmer is connected

to the development system via 1x5 connector Figure 3-9. mikroProg™ is a fast USB 2.0 programmer with

hardware debugger support. It supports PIC10®,

dsPIC30/33®, PIC24® and PIC32® devices

in a single programmer. It supports over

570 microcontrollers from Microchip®.

Outstanding performance, easy operation

and elegant design are its key features.

mikroProg Suite™ for PIC® software

mikroProg™ programmer requires

special programming software called

mikroProg Suite™ for PIC®. This

software is used for programming

of ALL Microchip® microcontroller

families, including PIC10®, PIC12®,

PIC16®, PIC18®, dsPIC30/33®,

PIC24® and PIC32®. Software has

intuitive interface and SingleClick™

programming technology. Just by

downloading the latest version of

mikroProg Suite™ your programmer

is ready to program new devices.

mikroProg Suite™ is updated

regularly, at least four times a year,

so your programmer will be more and

more powerful with each new release.

Before attaching the programming connector, you have to solder the provided 1x5 male header to the programming pads (HD1).

4. Buttons and LEDs

The board also contains a 01 reset button

and a pair of 02 buttons and 03

LEDs, as well as an ON/

OFF switch. The Re-set button is used

to manually reset

the microcontroller—it

generates a low voltage

level on the microcontrol-

ler’s reset pin. LEDs can be

used for visual indication of

the logic state on two pins (RD4

and RE4). An active LED indicates

that a logic high (1) is present on the

pin. Pressing any of the two buttons can

change the logic state of the microcontroller

pins (RD7 and RH3) from logic high (1) to log-

ic low (0). In addition to the onboard ON/OFF

switch, two pads (EXT and PSW) allow you to

connect your own external switch.

6. Oscillators

Board is equipped

with 8MHz crystal oscillator (X1) circuit

that provides external clock

waveform to the microcontroller

CLKO and CLKI pins. This base

frequency is suitable for further clock

multipliers and ideal for generation of

necessary USB clock, which ensures proper

operation of bootloader and your custom

USB-based applications.

Most microcontroller pins are available for further connectivity via two 1x26 rows of connection

pads on both sides of the clicker 2 for PIC18FJ board. They are designed to match additional

shields, such as Battery Boost shield, Gaming, PROTO shield and others.

9.1 mikroBUS™ pinouts

clicker 2 for PIC18FJ employs a solution to optimize

the use of available pins and MCU I/Os. The PWM SEL jumper (Figure 9-2) enables two modes of

use for the second available PWM line:

1 The default position of the jumper is for

applications when you’re not using the PWM line on

the 1x26 pinout on the right side of the board. This

keeps this PWM available through mikroBUS™ 2

2 If you resolder the jumper into the second

position, it would turn the PWM line on mikroBUS™

2 into a GPIO. You would use this in scenarios

where you already utilized the PWM through the

1x26 pinout (which would make the PWM pin on

mikroBUS™ 2 unusable)

Digital lines*

Figure 9-2:

PWM SEL jumper

Up to now, MikroElektronika has

released more than 90 mikroBUS™

compatible click boards™. On

the average, one click board

is released per week. It is our

intention to provide you with as

many add-on boards as possible,

so you will be able to expand your

development board with additional

functionality. Each board comes

with a set of working example

code. Please visit the click boards™

currently available boards:
