Using PCS0 and PCS1 with CMSIS LPSPI driver

mh_AS — Fri, 28 Oct 2022 16:07:00 GMT

Hello. I am currently using SPI4 on an IMXRT1064 using the CMSIS LPSPI config provided in the periperhals view of MCUXpresso. I want to be able to programmatically swap between PCS0 and PCS1 (as we have 2 devices connected to that bus) but cannot find how this is achieved. It looked like this would work but I think this isn't for the CMSIS driver:

LPSPI_SelectTransferPCS(LPSPI4, kLPSPI_Pcs1);

Any help is greatly appreciated.

Hi,

Yes, you are right.

LPSPI_SelectTransferPCS() is the LPSPI module SDK driver API function, not belongs to CMSIS style driver.

I will report this info to SDK software team.

best regards,

Mike
