I am very new to the Portenta and am having trouble getting the full potential out of the onboard ADC. I am trying to read the output of an image sensor running at 200KHZ, so I need the analog read of the portenta to be quicker than 5us. The quickest I can get it to be is roughly 32us per reading and am hoping somebody might have some sample code for how to get a faster reading? I am not interested in it being extremely accurate either, so 1 sample per reading is plenty for me.
Any help is appreciated!
