Description

For time critical code, it could be needed to calibrate the ulp clock.

https://docs.espressif.com/projects/esp-idf/en/v4.2/esp32/api-guides/ulp_instruction_set.html#note-about-instruction-execution-time

Does it is possible to do it with micropython-esp32-ulp lib ?
If not is there a workaround ?

Thanks

Research direction

Start with the linked ESP-IDF ULP instruction-set documentation and inspect the micropython-esp32-ulp library to determine whether ULP clock calibration is supported. Define whether calibration can be exposed or whether a documented workaround is needed; the issue names no files or tests, so the implementation scope remains uncertain.
