The 28-Pin Demo Board I
PICkit™ Serial Analyzer using the I
the I
Demo board is programmed to emulate an I
EEPROM.
This chapter discusses:
• Hardware
• Firmware
• I
• Slave Devices
• Functions
The 28-Pin Demo Board (DM164120-3) is populated with and configured for:
• PIC16F886 configured using the 8 MHz internal clock
• 32 kHz Tuning Fork Crystal connected to Timer1 Low-power Oscillator
• Four LEDs (DS1 through DS4) connected to RB0 through RB3
• Potentiometer (RP1) connected to RA0/AN0
• Push button (SW1) connected to RE3/MCLR
For more information about the 28-Pin Demo Board hardware, see the 28-Pin Demo
Board User’s Guide (DS41301).
The demo program source code and *.hex file can be found on the PICkit Serial
CD-ROM at D:\28-pin Demo Board\Firmware\.
The firmware is structured as multiple ‘modules’ representing functional components.
Each module contains, at minimum, an “initialization” routine (MODULE_INIT) and a
“service” routine (MODULE_SVC). Each initialization routine is called from MAIN once
on Reset. Each Interrupt Service Routine is called sequentially and continuously from
the MAIN Idle loop. Interrupt Service Routine is provided for the I
other modules are serviced in turn from the MAIN ‘Idle loop’.
