Wrong code generation for ADCs on STM32H743XIH6 in STM32Cube V1.11.2

Associate II

There are two problems.

The first is that if the clock prescaler for ADC1 is changed, the prescaler for ADC2 also changes accordingly and vice versa. This can be observed directly in the CUbeMX IDE with a new generated C project.


The second problem is, that the ADC3 can be configured independently, but the for the code generation, also the clock prescaler of ADC1/ADC2 is used.


I have only seen this with the clock prescaler, but perhaps other settings are also affected.
