Thanks for the reply. In terms of what ‘should’ be coming out of the LED0 pin, what voltage should that be?
I thought that maybe it was because of a bad solder on the IR transmitter, but I wasn’t sure until I removed it altogether. Still don’t get a green LED.
If I were to try one last time, it would probably be to replace the entire FPGA, but it is strange how all of the firmware code seems to run ok on it, which is why I didn’t start there. I’ve checked for bridges with a multi-meter on all chips, all pins. They’re good. Also checked that all legs were soldered in.
