Introduction Ready for PIC® Board is the best solution for fast and simple development of various microcontroller applications. The board is equipped with the PIC18F25K22 MCU that is placed in DIP 28 socket and contains male headers and connection pads for all available microcontroller ports. The pins are grouped according to their functions, which is clearly indicated on the silkscreen. The MCU comes pre programmed with mikroBootloader, but it can also be programmed with mikroProg™ programmer.

1. Power supply Figure 1-1: USB power supply Figure 1-2: AC/DC adapter power supply Figure 1-3: screw terminals power supply Ready for PIC® board can be powered in three different ways: via USB connector (CN1), via adapter connector using external adapters (CN2) or via additional screw terminals (CN46). The USB connection can provide up to 500mA of current which is more than enough for the operation of every on-board module and the microcontroller as well.

2. Programming with mikroBootloader You can program the microcontroller with bootloader which is pre programmed by default. To transfer .hex file from a PC to the MCU you need a bootloader software (mikroBootloader) which can be downloaded from: mikroBootloader software note Before starting mikroBootloader software, connect Ready for PIC® to a PC using a USB cable provided with the package http://www.mikroe.com/eng/downloads/get/1808/ ready_pic_mikrobootloader.
Identifying device COM port step 1 – Choosing COM port 01 02 01 03 Figure 2-3: Choosing COM port Figure 2-2: Identifying COM port 01 Open Device Manager window and expand Ports section to see which COM port is assigned to Ready for PIC® board (in this case it is COM3) Page 11 01 Click the Change Settings button 02 From the drop down list, select appropriate COM port (in this case it is COM3) 03 Click OK
step 2 - Establishing Connection step 3 - Browsing for .HEX file 01 01 Figure 2-4: Connecting with mikroBootloader Figure 2-5: Browse for HEX 01 Press the Reset button on Ready for PIC® board and click the Connect button within 5s, otherwise the existing microcontroller program will run. If connected, the button’s caption will be changed to Disconnect 01 Click the Browse for HEX button and from a pop-up window (Figure 2-6) choose a .

3. Programming with mikroProg™ programmer The board is equipped with mikroProg™ connector pads, which allow you to program the microcontroller using external mikroProg™ programmer. Before attaching the programming connector, it is necessary to make a few adjustments (Page 16).
Figure 3-2: cutting copper between pads Figure 3-3: placing 2x5 male header Figure 3-4: soldering 2x5 male header on the pads Figure 3-5: Connecting mikroProg™ programmer First you need to cut copper between pads for the external programmer, Figure 3-2. By doing so pins RB6, RB7, MCLR and VCC on MCU will be separated from the rest of the board. After that it is time to place (Figure 3-3) and solder (Figure 3-4) a 2x5 male header on the pad (CN5) .

4. USB-UART Fast on-board FTDI® chip allows you to communicate with a PC or other UART devices using USB-UART connection. USB-B connector (CN1) is used for connecting the USB cable. RX (receive) and TX (transmit) LEDs will indicate communication status. Before connecting the board to a PC, make sure that you have the appropriate FTDI drivers installed on your operating system. Drivers can be found at the following URL: Figure 4-1: connected USB-UART http://www.ftdichip.com/Drivers/VCP.
5. Prototyping area Figure 5-2: schematic of three LEDs connected to microcontroller pins as shown in Figure 5-1 Figure 5-1: Proto area usage RA2 RA1 RA0 DATA BUS GREEN RED YELLOW LD1 LD2 LD3 R1 R2 R3 Proto area allows you to expand your Ready for PIC® board with additional functionality. It can be done by placing your additional components on available prototyping area. Pads are arranged in standard 100mils distance form factor.
6. Pin headers and connection pads 01 03 05 02 04 Each microcontroller pin is available for further connections through four on-board 2x5 connection headers and two 1x28 connection pads. Pins are grouped in four PORT groups (2x5 male headers) as well as per their functions (1x28 connection pads), which makes development and connections much easier. Everything is printed on the silkscreen, so that there will be no need of using microcontroller data sheet while developing.
