Capture of a single sample. The RDY rising edge informs the RP2040 that a sample has been converted.
A rising edge interrupt detects this, and allows the main thread to read the data.

That's what you see here.

Nice update Jan.

I am curious, is there anyway to set up a DMA for the ADC on the Pico?

Good work with the mod! Just curious, did you find the footprint easy to use? I modified it to try to be easier to hand-solder (it is slightly thinner pads than usual, and slightly longer to take up the excess solder).
