I was just looking through the LIRC transmitter information, as well as the neo's CPU information and came across this tidbit in the CPU users manual.<br><br>**RS-232C interface<br>If users want to connect the UART to modem interface (instead of null modem), nRTS, nCTS, nDSR, nDTR, DCD and nRI signals are needed. In this case, the users can control these signals with general I/O ports by software because the AFC does not support the RS-232C interface.**
<br><br>Since homebrew LIRC transmitters only use the high/low nature of the DTR signal line I think my original idea of using a software controlled GPIO pin may still work?? We would just need a driver for LIRC to interface with the GPIO that cycled the pin high/low at 38400. However that right there could be the problem, im not even sure if its possible to do that in software, given the hardware we have. Any ideas?
