Hi,

I would like to set the SPI clock to 16MHz.

Is it possible to set the MCSPI source clock to SOC_RcmPeripheralClockSource_OSC_CLKX2 (80MHz) declared in soc_rcm.h?

The SDK is MMWAVE_L_SDK_05_05_02_00.

Hai Sir,
I am also working on the IWRL1432 board and have a couple of doubts.

I want to send level sensing data to another MCU via SPI.
- I asked this question on the E2E forum and received a reply:
  https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1466383/iwrl1432boost-read-the-values-spi-communication/5630932#5630932
Based on the response, I added MCSPI code to my level sensing application.
- Is this the correct approach?
- If not, could you guide me on the proper way to integrate SPI communication into my level sensing code?

Thanks!

Hello Taguchi-san,

SOC_RcmPeripheralClockSource_OSC_CLKX2 should be equivalent to what is defined in firmware as the Device XTAL clock frequency. 80MHz is not supported, the highest value being 40MHz.
