Hello!
I have a problem with the ADC on my STMF4Discovery Board.I am reading two analog voltages with ADC1 in triggered injection mode.The voltage on the pin with injection rank 1 always has a peak at the injection event. Even when i change the ranks of my two channels, the one with rank 1 always has the peak.Here are some Scopes:CH1 (Yellow) is ADC_CHANNEL_8CH2 (Cyan) is ADC_CHANNEL 15Here ADC_CHANNEL_15 has rank 1:Here ADC_CHANNEL_8 has rank 1:Do you have any idea how i could fix this?Thanks in advance! #adc #noise #injected #discovery2014-07-23 01:07 AM
Also, the first ADC channel always has more noise on it.
