NEC IR to PS2 keyboard converter
This device converts IR commands received on NEC protocol to keypresses on PS2 keyboard.
Main purpose for this device is to allow controlling a media center PC (eg. MythTV frontend) via a standard IR remote.
- Computer interface = PS2
The PS2 interface is selected as it allows waking up most motherboards and also in many cases is left otherwise unused in favor of USB keyboard.
- IR protocol = NEC
NEC protocol was selected for the design as I had a suitable RC that used it with suitable large number of buttons (from Terratec Cinergy XS diversity)
- Microcontroller = PIC16F84A
Well had these obsoleted parts lying around so it was used, some small adaptations might be needed for PIC 16F628 to be used instead
