Blinka's usb_hid.py with MicroPython throws ImportErrors #696

Closed evgeni-student closed 1 year ago

evgeni-student commented 1 year ago

Hello! I have the latest MicroPython 1.20.0 installed on Raspberry Pi Pico H and I want to use CircuitPython the usb_hid.py module from Adafruit_Blinka. I have PlatformDetect-3.48.0 and Adafruit Blinka 8.20.0. I have the following directories in the lib folder and a sample MicroPython and CircuitPython mixed code runs as intended. library The issue I have appears when I try to import usb_hid with the intention to use adafruit_hid.keyboard, adafruit_hid.keycode, adafruit_hid.keyboard_layout_us and adafruit_hid.consumer_control. error_msg I already seen these issues #586 and #230. I tried adding try/catch on the inner code but it just results in other errors like these: File "/lib/usb_hid.py", line 19, in ImportError: no module named 'pathlib' and ImportError: no module named 'atexit' After installing typing from Thonny's manage package interface pictured below: typing and running the code again, the following ImportError occurs: sequence_error further still when I change the import to just import typing and then wrapping the from abc import abstractmethod, abstractproperty part in try/catch I again bump into more problems like the one below: atexit_error

Thank you for your help in advance.

the failures shouldn't be coming up but im also pretty sure the hid library wont run because micropython does not have core HID support for RP2040 - if you want to act like a keyboard you'll need to use circuitpy

Thank you for your comment. Yes, when I use CircuitPython only it works, but my intention behind using MicroPython is to utilize hard interrupt handlers rather than polling a CircuitPython while loop.

Looking through their documentation, it looks like the only board they added it to was the pyboard, which is also supported by Blinka.

I guess I would just have to wait until MicroPython gets native HID support for RP2040. Thank you for your help.

You're welcome. Closing for now.
