ADC conversion using End of Conversion Selection?

SWenn.1

Good evening....

I would like to do an A/D conversion on Channel 9 and Channel 10. I have a timer that goes off every second and within this ISR I call HAL_ADC_Start_IT. The ISR gets called upon conversion complete. Now the question is End of Conversion Selection: Should it be 'End of Single Conversion' or 'End of Sequence of Conversion'?? Even though I am sampling multiple channels is this considered a sequence or a single conversion of multiple channels, given that I am using a timer to trigger this single event every second???? This is not explained well and confusing.

Thanks

Steve

depends on your selection, what ISR you want/need:

There is no EOS flag!

But, the End of Conversion (EOC) flag (in ADC_SR reg) can be triggered at the end of each conversion or at the end of a sequence, depending on the EOCS bit (in ADC_CR2 reg)
