Hi all,
I'm using the LPC1769-Board.
My goal is to read all ADC Channels in Burst-Mode via DMA. It all seems to work well but there are some nasty peaks within this curves as you can see in the atached image.
I've already checked if it has something to do with the reference voltage which is not the case...
Is there anybody who had the same problem or has an idea where this could come from?
Thanks!
