How can I determine root cause of a damaged ADC module on STM32L151?

I have a product that uses the STM32L151. One of our in-house test products was reporting inaccurate measurements on all ADC channels where the reported value is higher than it should be (example - battery voltage range is 0 to 10V. Real voltage is 8...

ADC Trigger scan mode

I am using stm32h745i-disco.I need to run ADC in ScanConvMode mode because I need the exact sampling frequency.But my ADC constantly gets into HAL_ADC_ErrorCallback with code 2 (Overrun).I noticed that the call frequency of HAL_ADC_ErrorCallback is s...

Inconsistency in the specification of STM32H753ZI maximum SPI4,5,6 clock frequency

Hello,The datasheet of STM32H753ZI specifies the maximum SPI clock frequency that the chip supports. For SPI4,5,6 in Master mode it is 50MHz in rev V and 100MHz in rev Y (tables 105 and 204) for highest power supplies.However in the reference manual ...
