Update quickstart to use mip instead of upip about micropython-esp32-ulp HOT 7 CLOSED

ImportError: can't import name preprocess

this will be the same thing as util.py - the file did not get installed correctly.

Basically the mip install crashed while downloading preprocess.py so it and all files thereafter are corrupt/missing. You can see the full list of files that should have downloaded in the gist: (one more file that should have come after the mip crash during preprocess.py).

Make sure to manually copy all the missing files to the esp32_ulp directory on your ESP32.

Thanks for the report. It's definitely something that needs to be fixed.

I'm working on that one (should have it soon), but currently focusing on finishing S2/S3 support.

For now you could use mpremote on a PC to copy the necessary files to your ESP32.

First clone this repo, then from within the repo root, run:

pip install mpremote  #if not yet installed
mpremote cp -r esp32_ulp :

Then it will work.

from micropython-esp32-ulp.

Potentially this would work too (I havent tested it, but I made the necessary package.json available as a Gist):

# on the ESP32
# make sure network is connected
import mip
mip.install("https://gist.githubusercontent.com/wnienhaus/5a30dd2ac7000764b065b44c5341f1e9/raw/54e1d43dbb0761b10134a34ca70d272064b66987/package.json")

Wow thanks for the fast reply!

Your command almost worked:

Further after ignoring the oserror, and copying the example file counter.py, I got this:

>>> import counter
Traceback (most recent call last):

  File "counter.py", line 15, in <module>
  File "/lib/esp32_ulp/__init__.py", line 1, in <module>
ImportError: no module named 'esp32_ulp.util'

I had to copy over util.py, which then results in:

>>> import counter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "counter.py", line 15, in <module>
  File "/lib/esp32_ulp/__init__.py", line 3, in <module>

This was exactly the problem thanks a bunch!

I'll reopen this, because one still cannot install using mip, and the latest MicroPython no longer has upip. (The above is just a workaround).
I'll add the necessary support next, by adding a valid package.json file and by updating the documentation.
