Dear all
I use the ADC of an STM32L051. According to the errata, the first measurement is not accurate if the ADC has been idle more than 0.5ms. I can observe the effect if I poll a certain channel.
In my application I want to convert 5 Channels every millisecond. DMA transfers the data into an array. The same error like in single mode with long delay can be observed.
I tried to add a dummy channel bevor doing the first channel I need – without success. Then I ran the sequence of 5 channels twice within 200ms. That does not help either.
Can anybody tell me how to mitigate this problem?

I wrote 200ms above. I wanted to say 200us (microseconds)...
