I have been looking into IrDA for EEG. There is a simplified protocol
called IrDA Lite which represents the bare minimum needed to comply
with the IrDA standard. IrDA Lite limits the baud rate to 9600 and
limits packet size to 64 bytes.
It is still not simple, IrDA requires several protocol layers
including hardware, driver/framer, link access protocol, link
management protocol, and transport protocol. I have been unable to
find any open source c code implementing IrDA lite for a secondary
device. Additionally, I assume there will need to be work done on the
PC side so that the ElectricGuru (or whatever) software can interpret
the IrDA signal.
For the hardware, several companies manufacture IrDA transceivers.
The driver/framer would be microcontroller specific, but I think the
rest of the code could be written in C and would be fairly portable.
I am willing to do some work on the firmware, but I would be working
on a 68HC12.
