clicker 2 for PIC18FK schematic

1. Power supply

You can supply power to the board with a micro 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 onboard

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.t

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.

NOTE

2. PIC18F67K40 microcontroller

The clicker 2 for PIC18FK development tool comes with the

PIC18F67K40 device. This 8-bit low power high performance

microcontroller is rich with on-chip peripherals and features

128KB of program memory and 3568 bytes of RAM.

Figure 3-1:PIC18F67K40 microcontroller

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 (UART

mikroBootloader) which can be downloaded from:

3.1 Programming with mikroBootloader

step 1 – Connecting clicker 2 for PIC18FK

01

To start, connect the USB cable, or if already connected press the Reset button on your clicker 2 for PIC18FK. Click the Connect button within 5s to enter the bootloader mode, otherwise existing microcontroller program will execute.

After the mikroBootloader software is downloaded,

unzip it to desired location and start it.

Press Reset button on clicker 2 for PIC18FK board and wait

for 5 seconds. Your program will run automatically.

3.2 XPRESS bootloader

The XPRESS bootloader allows for easy drag and drop programming.When plugged into the USB it will show itself as a flash drive onto which you can simply drag a hex file for your MCU. The hex file can be generated by any compiler. After the hex file is placed onto the clicker 2 for PIC18FK it will program the main MCU. This functionality is enabled by the PIC16F1454 which acts both as a drag and drop programmer and Virtual COM port. The additional bootloader in the main MCU is not needed for this to work.

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.

Figure 3-10: Main window of mikroProg Suite for PIC® programming software

Figure 4-1: Two LEDs, two buttonsand a reset button

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 RESET button

is used to manually reset the

microcontroller—it generates

a low voltage level on the

microcontroller’s reset pin. LEDs

can be used for visual indication

of the logic state on two pins (RH3

and RD7). 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 (T2 and

T3) from logic high (1) to logic low (0).

5. Power management and battery charger

clicker 2 for PIC18FK features

LTC®3586-2, a highly integrated

power management and battery

charger IC that includes a current

limited switching PowerPath

manager. LTC®3586 also enables

battery charging over a USB

connection.

Figure 5-1: power management and battery charger IC

6. Oscillators

Board is equipped with 16MHz crystal oscillator (X1) circuit that provides

external clock waveform to the

microcontroller OSC1 and OSC2 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.

Figure 6-1:16MHz crystal oscillator module (X1)

PIC18FK microcontrollers has an integrated USB

module, which enables you to implement USB

communication functionality to your clicker 2 board.

Connection with target USB host is done over a

micro USB connector which is positioned next to the

battery connector.
