Adafruit ItsyBitsy M0 Express not recognized in mu

by imrekiss on Thu Mar 01, 2018 1:46 pm

Hi,

I installed mu editor and Adafruit ItsyBitsy M0 Express drivers on my Windows 7 computer. When I open mu, I get a message

Could not find an attached Adafruit CircuitPythondevice

The board is plugged in and multicolored led cycles. If I save the example program in mu, red led does not cycle. I installed on two Windows 7 computers and got same results.

Thanks

Thanks for the quick reply.

When I download the indicated driver package, I got an exe file that installs drivers. I did do that before. but there was nothing to drag to the ITSIBOOT (this appeared as predicted) drive as instructed.

The drivers are only for installing on the Windows 7 machine. Just wanted to make sure those were the ones you installed. Nothing needs to be done to the ItsyBitsy board.

but there was nothing to drag to the ITSIBOOT

You should only see that folder if you put the board in bootloader mode by pressing the reset button twice. Is that what initially shows up when you plug it in? You don't get a folder named CIRCUITPY?

When I plug in the board I get "Removable Disk (G)". CIRCUITPY does not appear in the drive list.

Can you open that drive? What are the contents?

Yes the drive is operable. The files are:

.fseventsd
Windows 7 Drivers
main
boot_out
README

OK, that looks correct. After you get that initial message:
Could not find an attached Adafruit CircuitPythondevice

does Mu behave OK? It sounds like you were able to save a file from Mu to the ItsyBitsy.

Yes I was able to save to the G drive. mu defaulted there. On my other computer it defaulted to the C drive. looking at the dates, I presumed that the newest file "simple" (which is the example program) should execute. Since it did not, I presumed that it had something to do with the board not being recognized by mu as described earlier.

Hi,

Just to mention that I have not been able to resolve the issues. the most obvious symptoms are:

1)CircuitPython does not seem to run the latest software on the drive
2)mu does not recognize the computer

Should CircuitPython be reloaded?

Thanks

Mu is still pretty new, so I'm wondering if that error message you get might be a false alarm. It sounds like it might be working despite it.

Yep, that can happen. Just depends on what's available for the computer you plugged it in to.

looking at the dates, I presumed that the newest file "simple" (which is the example program) should execute. Since it did not, I presumed that it had something to do with the board not being recognized by mu as described earlier.

It doesn't run by date, it runs by file name:
https://learn.adafruit.com/welcome-to-c ... ogram-file

Try this. Rename the file main.py (your settings are hiding file extensions, but that's the full file name) to not_main.py. This way no user code will run automatically. Next, try to open the REPL using the menu bar button in mu.

Thank you.

The naming convention worked and as per your suggestion, mu is just a bit buggy because the board is connected and the error message is meaningless.

Cool. So sounds like it is at least working. If you don't mind, please file an issue for what you've found:
