ELECTROSTATIC WARNING: The PIC-MX board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board. BOARD USE REQUIREMENTS: Cables:.8 meter USB A-B cable to connect PIC-KIT, PIC-ICD or PIC-ICD-POCKET to USB host on PC (if you use other programmer, you should read its specification in order to choose a cable). Hardware: PIC-KIT, PIC-ICD, PIC-ID-POCKET Or any compatible tool for programming and/or debugging!!!warning!!! When you want to program this microcontroller with PIC-ICD,

PIC-ICD-POCKET or PIC-ICD-TINY, before connecting the programmer to your target board, you should first connect the programmer to your computer and open MPLAB. There, first from menu Configure Select Device choose the microcontroller you are about to program, then from menu Programmer Select Programmer choose MPLAB ICD, wait while MPLAB is downloading operation system, and after ICD is connected check in menu Programmer Settings Power there is option Power target circuit from MPLAB ICD this option should be forbidden, you could not select it. Now it is safe to connect the programmer to your target board. Software: MPLAB IDE v8. + MPLAB C for developing your own applications. The demo software shows basic functionality and how to blink LED (C source and HEX), how to read a button (C source and HEX), the use of Timer (C source and HEX) and UART functions (C source and HEX). The sources are compiled with MPLAB C C compiler.

BOARD LAYOUT: POWER SUPPLY CIRCUIT: The typical way of powering the board is applying voltage to the power jack. PIC-MX requires be either (. 9.0)V AC or (.0.0)V DC applied to the power jack. The board can't be sufficiently powered by V DC power supply. The power consumption at V DC is round 70mA. For more options of powering the board refer to the schematic. RESET CIRCUIT: PIC-MX reset circuit includes a capacitor C (00nF) and a resistor R (0KΩ). CLOCK CIRCUIT: Quartz crystals at 8MHz and.78khz are connected to PIC-MX.

GETTING STARTED In order to get started you need:. PIC-MX board. Power supply (-VDC/.-9VAC). ISP programmer. Cable to connect the programmer to the PC. Cable to connect the programmer to the board. Compiler/Assembler We provide here an example configuration but you could use any compatible programmer/compiler/assembler and the corresponding cables. Example configuration:. PIC-MX board. V DC power supply adapter. Programer PIC-KIT. Cable to connect the programmer to the PC USB cable A-B. Cable to connect the programmer to the board ICD cable (ISCP). Compiler/Assembler MPLAB v8. IDE + MPLAB C To get started you first should apply power to the board, connect the programmer to the board and to the PC, open MPLAB and write your application. After that you should compile and build your project, then you should debug it and if the previous stages are successfully finished, to program PIC-MX. To get your application running you should disconnect the programmer from the board and reset the board.
