[STM32L151] STM32CUBEIDE 1.9.0, FW_L1 V1.10.3 SPI1 and SPI2 are missing options to set Clock Polarity (CPOL) and Clock Phase (CPHA)

[Alec Davis 2021]

 

I was able to resolve by adding to SPI2_Init

 /* USER CODE BEGIN SPI2_Init 1 */

 hspi2.Init.CLKPolarity = SPI_POLARITY_HIGH;

 hspi2.Init.CLKPhase = SPI_PHASE_2EDGE;

But STM32CubeIDE 1.8.0 with same version FW_L1 V1.10.3 does have the options as below

 

This is concerning, as upgrading to 1.9.0 then regenerating the project would change the auto generated SPI2_Init back to the default CPOL and CPHA

Hello @Community member​ ,

Thanks for sharing your finding, It is indeed a CubeMX issue, CPOL and CPHA are missing from SPI configuration.

Your way to resolve this issue is correct and that is the only workaround available at the moment. CPOL and CPHA config should be added manually within the user section in SPIx_init function.

 /* USER CODE BEGIN SPI2_Init 1 */
 
 hspi2.Init.CLKPolarity = SPI_POLARITY_HIGH;
 hspi2.Init.CLKPhase = SPI_PHASE_2EDGE;
 
 /* USER CODE END SPI2_Init 1 */

With this being said, I raised a ticket to the dev team to solve this issue. I will keep you posted.
