I'm working with circuitpython, and need access to the micropython uctypes module. I've downloaded the micropython files from github, but can't seem to find the module. Can anyone help?
See this CircuitPython issue: this is a known thing, and it looks like none of the ports actually have the uctypes module enabled: for that, the MICROPY_PY_UCTYPES preprocessor definition must be non-zero when building and this is normally set in the port's mpconfigport.h but that is not the case here.
So either you'll have to build yourself (see e.g. https://learn.adafruit.com/building-circuitpython/) and either add said definition into mpconfigport.h or pass it on the commandline, or find an alternative solution (same link mentions the struct module could be used instead, which it might indeed depending on the exact usecase).
