Troubleshooting

My Serial prints at the start of the program are not appearing in Serial Monitor.

• This is an small issue with all RP2040-based boards. By the time the COM Port appears and Serial Monitor can be opened, the RP2040 may have already begun running its program for a few seconds.

• 2 solutions for this:

  • Wait for Serial Monitor to be opened before printing

  void setup()
  {
      while (!Serial);
  
      //normal void setup() code can go here
  }
  

  • If you need to run your program with the robot being, you can delay void setup() for a few seconds.

  void setup()
  {
      delay(5000);
  
      //normal void setup() code can go here
  }
