PICList Projects

These projects have come from the PICList community. They are good general purpose usefull projects for beginners with lasting value for the experts and great code samples to augment the routine library.

PIC INSIDER by Atanasios Melimopoulos A new ICD aproach. Just connect it to any (user selected) single I/O pin of your pic-hardware and you will have a complete free debugging tool for any 12Fxxx, 16Fxxx and 18Fxxxx PIC-based application.

Ralph Stickleys' Serial Register Monitor: Borland C 3.1, DOS program and PIC asm code for RS-232 Poll and display all on-chip variables. Parses the MPLINK map file for symbolic display.

John Andrews' PICos for the 17C756. Monitor and change registers, port pins, A2D, Capture channels and PWM, send and recieve data to / from I2C and EEPROM via simple text commands on USART1.

"Free" ICD: Build your own In Circuit Debugger and program and DEBUG the newer PICs

PIC 16F628 GSM Monitoring and Control System Four inputs, one power output prepared for monitoring and controlling through SMS messages on your mobile phone. Send a SMS and turn on the relay. Get an SMS if the inputs are activated or the power is lost.

Denis Petrov's wwwPic The first free source web server in a PIC.

Andrew D. Vassallo's Simon game.

Delay Code Generator

Brendon Archibald's Psychoanalytical (restarting countdown) Timer

Simple Bike Computer by Fred Maher

From the CHEAPIC tutorial:

• bincnt.asm - Count in binary on 4 LEDs
• swcnt.asm - Count switch closures.
• eggtimer.asm - Countdown timer, displays minutes and 10's of seconds on LEDs
• morsenbr.asm - Send numbers 0-9 out on piezo speaker
• binclock.asm - A clock which displays hours and minutes in BCD on LEDs at keypress
• combo.asm - a combination lock which remembers a selectable combination, even when power is removed
• alphabet.asm - Sends ASCII characters to the COM port of a PC for display
• worktime.asm - Uses a LCD to display a timer that can be started and stopped by pushbutton
• shotmr0.asm - Display TMR0 on a LCD atter counting pulses on RA4 for one second
• therm.asm - Display temperature on a LCD using a thermistor as the sensor

• http://www.sskteracon.com A small home controller based on PIC16F873A. With the appropriate sensors the controller can monitor physical variables such as pressure, temperature, light intensity etc, process the information and then use the result to control up to three physical devices such as motors, heaters, lights or other appliances around the home or office. You can program your appliances to operate automatically in conjunction with your weekly and daily schedule, manualy turn them on/off from your PC or use the controller as a process ON/OFF controller to regulate some kind of physical variable to the desired value.

Questions:

• SPAMimythili18KILLspam at -Remove-yahoo.com asks: " I have seen the instruction set for a A/D converter for 16F873.
  Can i apply the same program for 16F88? Or if there are any changes what are they?" >> James Newton replies: Check the datasheet.
