Iam reading an analog value on the GPIO36 PIN with i2s dma.
The thing is when an interrupt comes on GPIO39 or 34 or 35, my i2s adc read goes crazy and generating very wrong reads.
The interrupt comes from an RFID reader when a member touching its tag to it.
These pins are INPUT only pins, so the interrupt should goes fine and smooth.
But thats not the case.
What is happening?
