I have two devices connected on one SPI Port. The first device is a flash memory that takes either Mode 0 or Mode 3 SPI waveform. The other device is a DAC that takes Mode 1 waveform.


The question is, can I have those two devices on the same SPI port?

The question implies ,of course, that I have to setup the SPI waveform (choose which mode to use) every time I communicate with either device. is that possible to do?or is that a "healthy" thing to do?

The flash memory is accessed every 1 second (minimum).

The DAC is accessed randomly.


Thank you,
