Example sketch (si5351) does not start serial terminal #19

Open alexudanis opened 2 years ago

alexudanis commented 2 years ago

Arduino board: Trinket M0

-Arduino IDE version: 1.8.19

List the steps to reproduce the problem below:

Install SI5351 lib, open the example program, upload the example program to trinket, and open the serial monitor.

The following fixed the issue: Serial.begin(9600); while (!Serial); //added this in Serial.println("Si5351 Clockgen Test"); Serial.println("");

There's nothing in the loop() for the example sketch. The serial outputs are most likely working, just happening faster than one can manually open the Serial Monitor after the sketch upload. So they get missed and fly off into the ether. Adding while (!Serial); as suggested above is a simple fix.
