Codebra

Codebra is a micropython web-editor/repl. I had rp2040s in mind but it should work for other boards.

Programs on the left will be uploaded as main.py. On the right you can use the REPL.

To get started:

flash your board with micropython

• download the uf2.
• plug in your xiao while holding down the boot button
• drop the uf2 onto your board

connect to the editor and start programming

• hit the connect button (the first time you will have to authorize the port)
• start programming!

Here is an example program

from machine import Pin, Timer
led = Pin(25, Pin.OUT)
timer = Timer()

def blink(timer):
    led.toggle()

timer.init(freq=2.5, mode=Timer.PERIODIC, callback=blink)
