Hi All,
This is an interesting error,
“Install PiicoDev_RFID_Expansion.py for full functionality”
Place tag near the PiicoDev RFID Module
The RFID tag is read in without a problem , I have the “PiicoDev_RFID_Expansion.py” in the Lib directory of my PicoW .
as you can see in the Picture, the interesting thing about this , that if you put it in the root Dir, you don’t get that error?.
so the file looks like a library like the Piicodev_unifiied.py , is this the case with the RFID expansion?.
Essentially what it does is try and import the expansion library file, and if it can’t (like if it’s in a subfolder), it’ll spit out that error message.
If you’re on a micro:bit you’ll get a different message (hence the != microbit check above this), as the micro:bit doesn’t have enough flash to store the expansion, so you don’t want to prompt a user to try.
I’m not crystal clear on (Micro)Python’s import rules (I’m more of a C man), so I’m not sure why the subfolder is causing the error, you could try just running from PiicoDev_RFID_Expansion import * in the REPL in order to see the uncaught error message.
