Responding to: ???'s previous message

I also made another PCB, with some diagnostic LEDs, and it is pretty clear that Data from MISO dont reach PC.


Craig Steiner had diagnosed the same problem in the thread I mentioned earlier. I remember he had to insert series resistors in the MISO / MOSI lines (about 100-150 Ohms).

You better check that thread again, it seems you are facing the same problem.

Good Luck
