This code is for a simple RGB LED controller for 1 RGB LED using a PIC12F675 (or PIC12F629). The pattern is determined by the data in the EEPROM. When the PIC needs a new target for the PWM, it loads it from EEPROM. Pin 4 (GP3) is pulled high because it is used to switch between displays. Please see the source code for more information; the structure and design is commented. The operation of the controller is very simple and so is the wiring. Read More

PIC18LF2550 2.4GHz Serial Link
I wanted to make a wireless serial link that would allow me to send and receive data between Microchip PIC microcontrollers and a computer. I found some very useful information and some helpful code for utilizing a Laipac TRW-24G 2.4GHz wireless transceiver with a PIC16F88 as a wireless serial link. The PIC16F88 is a nice little chip that provides a number of useful features (including an onboard USART and the ability to use a bootloader). I am a fan of the PIC16F88; however, I believe that the PIC18 series are much more robust, so I created a circuit that would allow much more flexibility in design and deployment. This project is a relatively simple circuit that utilizes a PIC18LF2550 microcontroller and the Laipac TRW-24G 2.4GHz transceiver to create a wireless serial link. Read More
