STM32F103 ADC scan mode different HighThreshold values for different channels

BBurg · ‎2024-05-16

Hello,

I use the ADC1 with 5 channels in scan mode to obsurve different voltages.

Is it possible to define different AnalogWDGConfig.HighThreshold values for the channels?

Thanks,

Birgit

Unfortunately, Analog Watchdog is linked to ADC instance and could be configure for a single channel only or all channels in the same time.

There is probably a way to change the High Threshold on-the-fly based on DMA triggered by ADC but it has to be tested and timing can be a constraint.
I could have a look on this proposal.

Best Regards,
