cmantunes Posted October 10, 2015 Report Share Posted October 10, 2015 Hello! I've been playing with my Duo and decided to test all the wings. I noticed that on wings CH and DL, we have the AVR programming pins active, which were interfering with my tests. I was just using the 4-button/4-led wing for this purpose. What is the best practice to prevent the AVR from interfering? Thanks! Carlos Quote Link to comment Share on other sites More sharing options...
johnbeetem Posted October 11, 2015 Report Share Posted October 11, 2015 I'm only using the FPGA on my Papilio DUO, so I force the AVR into reset by setting ARD_RESET (FPGA pin 139) low. I think this makes all AVR I/Os high-impedance. 1 Quote Link to comment Share on other sites More sharing options...
