A few weeks back I used the following technique to troubleshoot a software issue. Many here have done similar. The following discussion might help new users. • If others can add to this discussion please do so. • New users should also remember, using Serial.print() is still a valid way to troubleshoot many/most problems. You will need to have either a digital oscilloscope or a logic analyzer. Images seen below were made on a 350 MHz Rigol oscilloscope; however, a lower band width digital …
