I am attempting to connect a DAC (DAC1220E) and ADC (MCP3550) to the raspberry using the SPI. The DAC uses a single port for data transfer (in and out), the ADC only has a port for OUT/RDY. I looked into activating the bidirectional mode on the RPI4, but could not find a clear route for this.
Is it possible to set the SPI interface to bidirectional mode on the RPi4? More concretely: can SPI1 (3 CE) be turned on to birectional mode?
How do I enable this function?
Alternatively, is it possible to interface MOSI/MISO ports directly to a SDIO?
Any suggestions and help are greatly appreciated.
