REPL prompt

picocom

To connect directly to the REPL of your microcontroller, launch a Terminal (click the blue + icon at the upper left of Jupyter Lab and then the Terminal icon). At the shell prompt type

picocom -b115200 /dev/ttyUSB0

Hint: If MicroPython displays no output, it may be in “raw repl” mode. Type ctrl-B at the console to return to the “friendly repl”.

rshell

You can also use David Hyland’s rshell in ide49:

iot@server:~$ rshell -p /dev/ttyUSB0
