This is yet another IR remote signal analyser which can capture IR signals and display its waveform via PC software. This project started as a way to send IR remote control signals from a PC to control hi-fi equipment, etc. A front-end program written in Java will run on the PC and communicate with a PIC based circuit via the serial port. The PIC based circuit listens to commands on the serial port and sends out the IR signals.

The IR analyser is build around PIC16F876 microcontroller which drives one input along with standard LED indicator to show incoming IR signal. Another LED indicator lights when learning mode is on. And of course there is a IR transmitting LED which can send IR signals to desired remote equipment. IR analyser can understand commands via RS232 input or simply send received signals to PC front end programs. PIC program is written in pure ASM language and front end program is written in Java.
