Olympus RM-1 IR Shutter Release
Simple programme that replicates the shutter release from the RM-1infra red remote control.
I have used a 16F877A as this is part of a larger project, it should work on any chip with PWM output.
The PWM output is used to produce the 38kHz Carrier frequency. Pin 16 is connected to an IR LED via a 220ohm resistor.
I have tested this on a Olympus E-3, although I believe this remote control works on other models.
