Installing micropython-esp32-ulp with mip on latest firmware esp32

[mjaspers2mtu]

Hello, I am trying to use the ULP on my esp32.

For this I wish to install this: https://github.com/micropython/micropython-esp32-ulp/tree/master

However the simple instruction of

import upip
upip.install('micropython-esp32-ulp')

does not work. I Found that this is because upip has been replaced by mip.
However, with mip, it is unable to locate this package.
I have tried:

import mip
mip.install('micropython-esp32-ulp')
mip.install('esp32-ulp')

Installing esp32-ulp (latest) from https://micropython.org/pi/v2 to /lib
Package not found: https://micropython.org/pi/v2/package/6/esp32-ulp/latest.json
Package may be partially installed

Can someone please explain how I can get esp32-ulp installed on '3.4.0; MicroPython v1.20.0-327-gd14ddcbdb on 2023-07-27'

I have not tried this, but according to the documentation, it is possible to install mip packages directly from github using the syntax

mip.install("github:org/repo/path/foo.py")  # Uses default branch
mip.install("github:org/repo/path/foo.py", version="branch-or-tag")  # Optionally specify the branch or tag

It's not obvious how to install this. For a package to be installable with mip it needs a package.json file and I can't see one in the GitHub repo.

Your best bet is to go to PyPi and download the files from here then copy them to the ESP32. I'm guessing that what's on PyPi matches what would have been installed with upip.

Good luck! You might like to report back if you have success as I'm sure others would like to use the ULP. Another thought is to raise an issue: the maintainers of the library might like to make it mip-installable. It's not a big job.

Thanks for the reply and looking into an alternative way to get this installed. I followed your tip and indeed created an issue:

ICYMI: MIP support was added in this PR: micropython/micropython-esp32-ulp#94
You can now install micropython-esp32-ulp with:

import mip
mip.install('github:micropython/micropython-esp32-ulp')
