TROUBLESHOOTING GUIDE
Is your CPX broken or not running code? Read below.
Now this is really important. Your CPX is a USB stick that can hold as many Python files as 2MB will allow but it can only run or execute one python script at a time. Furthermore it will only run two types of files. It will run code.py if it exists and if it can't find code.py it will run main.py If the CPX can't find main.py or code.py it will just not do anything. If you have two versions of main.py or a combination of main.py or code.py it will run one of them and not the other. Make sure you only have one version of main.py or code.by but not both! Some common things to check if your CPX isn't working.
Make sure you're using Mu in the right Mode
Make sure main.py or code.py is on the CIRCUITPY drive and not somewhere on your computer.
Make sure you are editing the right file in Mu. Do you have two versions of main.py?
Are you editing using Thonny or Spyder?
Are you editing a file on your computer? Make sure you are writing to the CIRCUITPY drive.
Unplug the CPX, close Mu and try again.
What if my CIRCUITPY drive doesn’t work anymore
First, try and reset the CPX to CPLAYBOOT and reflash the UF2 to see if that fixes it.
If that doesn’t work sometimes you just need to completely erase the CIRCUITPY drive so head over to this troubleshooting guide https://learn.adafruit.com/adafruit-circuit-playground-express/troubleshooting and follow some of the steps they tell you.
As a last resort you can try to download this UF2 and hopefully it will fix all errors and mistakes
