Honored Contributor --- Quote Start --- i don't know what you mean by driving conflict ........ can you explain please --- Quote End --- A driver conflict occurs when you connect two digital outputs together and configure one to drive high and the other to drive low. The DE0-nano pins can be configured as both inputs and outputs. If you have added some wire to the header so that you can output on one pin, and then read-back the signal on another, then it is quite possible that you have accidentally created a driver conflict. If you have not added any extra wires to the board, then this is not your problem. How are you measuring the signal on the pin? With a voltmeter or an oscilloscope? Cheers, Dave
