    Teensy 4.0 with PlatformIO - Serial.print ???

    Today I decided it was time to put the Arduino IDE to one side and get going at last on PlatformIO !

    Itís now installed and mostly working just fine; but for one tiny but very irritating issue:

    Code compiles, uploads, and runs without any errors but Serial.print displays nothing anywhere even though it works perfectly on the old Arduino IDE.

    I feel sure others must have fallen over this problem. Can anyone tell me the solution?

    I do hope so!

    There's a built-in tool labelled "Serial Monitor" that you can access from the tool bar at the bottom of the window, the icon looks kind of like an (American) electrical plug.
