SPI with several chip selects

Hello everyone,

I am using KSDK 1.1.0 on a FRDM-K64 board and would like to use an SPI port with multiple chip selects (multiple connected slaves). I used Processor Expert to set up the DSPI peripheral with two different master configurations that have their dedicated chip select pin.

My question is: How can I change between using the two chip selects? I would like to avoid to reinitialize the whole driver by using DSPI_DRV_Master(De)Init() each time. Is there any simple way to switch between several chip selects?

 

Best regards

Matthias
