Re: 3-Wire SPI Interfacing

Are you sure PIGPIO works for 3-wire? I just attempted it and it has the same issue as standard spidev. Here's my code for initialising the thing: if (gpioInitialise() < 0) { printf("Gpio init failed\n"); return 1; } fd = spiOpen(0,speed,(1<<9)); printf("Got fd: %d\n",fd); EDIT: Ignore me, I had wri...

When I configure my Pi A to use 3-Wire mode, however, it seems to only send the Chip Enable and Clock data over the pins, completely ignoring the MOMI pin. The Pi works absolutely fine in standard ...
