In terms of number 1, I tried to use analog discovery to look at SPI signals DOUT and CS. I also changed the address to PROD_ID. It seems like it only generated static. There were no clear cut digital signals. For number 2, do I just link it to a vdd pin on j1? I will include a picture of the noise. I removed the cables and a similar pattern of noise was also generated. I offset the signals for easier observation.
Thanks!
