I'm using cubemx for stm32f401.I have to address several SPI devices using a sing spi bus, and different chip selects.Each SPI device requires a different configuration of CPOL/CPHA.So when the bus is idle (when all the chip selects are high) I use H...

I corrected the issue by adding the code at the bottom of this post to a user section of generated stm32f4xx_hal_msp.c:This fix is specifically for my situation, and will have to be adapted for other SPI busses / CPUs.In my opinion the neglection of ...

I don't disable SPI before I initialize using the HAL_SPI_Init (). HAL_SPI_Init () however does disable SPI, which is as adviced by the reference manual.I already did the dummy write when Idle to be SPI compliant, that works, but I am now in the proc...
