SPI Mode switching

[ARORAPD]

Hi!

Can we switch the SPI Mode from Mode 1 to Mode 0 or vice versa in the same project ??

For eg. If I have set the SPI Mode to Mode 1 using my IOC which is required by one of my ICs but one of my ICs works on SPI Mode 0 so can I change the mode from Mode 1 to Mode 0 using the code only to control one IC.

Please reply ASAP!

Thanks

Hello @ARORAPD 

Yes, you can switch the SPI mode (such as from Mode 1 to Mode 0) at runtime in your STM32 project, even if you initially set one mode in your IOC file. This is done by de-initializing the SPI peripheral with HAL_SPI_DeInit(), updating the CPOL and CPHA settings in your SPI handle to match the required mode, and then re-initializing the peripheral with HAL_SPI_Init(). However, you must ensure that no SPI transfer is in progress and only one device is selected at a time when switching modes.
