Hello,I am experiencing the following problem. When I setup an ADC with DMA for 5 channels, occasionally I get lower readings than the expected ones. It also happens in some of our hardware of our production, but others perform ok. We have inspected ...

The issue was that the STM32 Cube MX has overwritten the configuration of the wake up pin, hence the microcontroller was actually running in sleep mode, but we could not wake it up.We can consider this issue as resolved.The offset calibration has bee...

This solution seems that is fixing the original problem (more testing is needed to verify further all readings), but while we testing, we get unresponsive devices after the introduction of the ST ADC calibration, hence no device has managed to comple...

Unfortunately the ST calibration does not solve the problem. The ADC problem has to do with the wrong gain as opposed to the wrong offset.The most interesting part is that now we experienced the problem in a device in another country than China. Henc...

In other words I will not get much of a benefit by calibrating based on Vrefint manually, because the LDO has a higher error margin? Hence the ST HAL calibration function should be good enough in my case?We will test tomorrow and verify if we get any...
