Hi I order this https://www.waveshare.com/wiki/Pico-Eval-Board so I can use it to learn programming the pico

Can I use this with the code you use to display the grbl info in the LCD in this projct?

Not without either adding host mode USB support to the grblHAL driver or wiring UART TX from the Teensy to GP1 (which would require you to cut the connection to the CP2102 - by trimming the Pico GP1 pin off?).

Parts of my code can be used, perhaps only the parser as it may be easier to use driver code already available for the attached display to display what you want.

Then the output stream from the Teensy has to be duplicated to the UART port if connecting via USB or Ethernet, I have changes coming which will make that easier - either via a simple plugin or a compile time definition.

I have to get the Pico MPG board sent off for manufacturing. Too little time for all I want to do...
