Connecting to serial tx and rx and a common ground (gray wire on the Saleae)
Then you make sure the communication you are trying to capture is happening, then you click the button on the Saleae software to start. In this case I restarted the FEZ Domino, which has software that sends serial commands to the Gainspan Wifi and then waits for the results. After I know the communication has taken place (my software flashes the LED 3 times when its done), I stop the Saleae Logic and it displays the results. The software graphs the bytes that are sent between the two devices on 2 different channels.
After turning an analyzer on “serial” the individual bytes are translated to their characters
