circuit python and ItsyBitsy M0 ExpressID:3727

by robert_iowa on Thu Mar 01, 2018 10:53 am

I'm trying to get started with a newItsyBitsy M0 ExpressID:3727. From my reading of the product description I thought that it would come with circuit python installed. The product was ordered last week and arrived Tuesday of this week.

I'm very new to this micro-python/circuit python world but it looks like an interesting python-like version of the Arduino environment.

When I connect the Isty to my Mac I see the following:

Roberts-iMac:itsyboot rjdavis$ ls -l
total 1026
-rwxrwxrwx 1 rjdavis staff 524288 Dec 31 1969 CURRENT.UF2
-rwxrwxrwx 1 rjdavis staff 104 Dec 31 1969 INDEX.HTM
-rwxrwxrwx 1 rjdavis staff 104 Dec 31 1969 INFO_UF2.TXT

Roberts-iMac:itsyboot rjdavis$ more INFO_UF2.TXT
UF2 Bootloader v1.23.1-adafruit.2 SFHR
Model: ItsyBitsy M0 Express
Board-ID: SAMD21G18A-ItsyBitsy-v0

I was expecting the the circuit python presentation with a main.py and such.

Is there a boot loader for circuit-python that needs to be added to the itsyboot disk ?

I found a file for the feather series of boards but not one for the Itsy series.

Any help would be greatly appreciated.

Thanks

Hi Robert! it sounds like you have the bootloader but not CircuitPython.

Can you try copying this file onto the drive with the CURRENT.UF2 file? https://github.com/adafruit/circuitpyth ... -2.2.3.uf2

Thanks,
Scott

Thanks that got me going.

For others: I also found (on GitHub) various collections of circuit python libraries and Alpha/Beta circuit python (Adafruit-micropython-tree) builds for multiple hardware environments.

Thanks again for pointing me the right direction.
