tinyPico - OSError: [Errno 19] ENODEV

Post by hybotics » Wed Jul 14, 2021 4:32 pm

Hi,

I have a tinyPico with Micropython and am getting the dreaded Error 19. There is nothing connected to the tinyPico and I have already erased flash and reflashed Micropython to the board. This did not have any effect. I have attached the complete library I am working with now - hybotics_ht16k33 in case the other files are needed.

I am getting:

Code: Select all

MPY: soft reboot
Traceback (most recent call last):
  File "main.py", line 20, in <module>
  File "/lib/hybotics_ht16k33/ht16k33.py", line 16, in __init__
  File "/lib/hybotics_ht16k33/ht16k33.py", line 22, in _write_cmd
OSError: [Errno 19] ENODEV
MicroPython v1.16 on 2021-06-23; TinyPICO with ESP32-PICO-D4
If I knew more about what the error is trying to tell me, I might have a better chance of figuring this out and fixing it. This is to be a port of Adafruit's ht16k33 library.

Am I missing something?

It sounds like the code is trying to communicate with an external device and that device isn't connected. You did say that nothing was connected right?
