Processor Expert SPI

Hi,

I'm trying to configure SPI Master mode via Processor Expert on CodeWarrior. I'm wondering if it is possible to configure the chip select pin as a general purpose GPIO and manually set this pin when I want to send a message. Currently, what I'm seeing in the generated code is that chip select is automatically updated by the send message function.

Thanks!

Hi @laonia

What MCU are you using?

Unfortunately Processor Expert can't make the settings you want.

Hi JRoberto,

I am using KEA128. In this case, if I would like to import the KEA128 library from S32 Design Studio, is there going to be any conflict with the generated code from Processor Expert? Or is it better to just write my own code for the SPI communication?

Thanks.

You would have to do many manual adaptations... On my personal opinion I'd make my own SPI code.
