Hi all,

I'm trying to interface a 3Wire timekeeper chip (DS1302) with Codesys. I'm actually stuck on the SPI interface since this chip is a 3Wire chip. i.e. MISO and MOSI are shared on one single pin. Is it possible to set the SPI_mode to 3Wire? It is using spiDev ... Is it in Codesys

Thanks,

Koen.
