circuitpython: ESP8266: time module missing sleep_us and sleep_ms
A lot of my drivers use time.sleep_ms() and time.sleep_us() for accurate timing, however, CircuitPython on the ESP8266 seems to be missing those.

Ah, I was wrong, I thought they are regular python objects. Thanks, that solves all the issues.
I think I can have a separate
utime.pymodule, withsleep_msandsleep_usfunctions implemented in terms oftime.sleep(). Then I can just tell users to put that module on their boards together with my drivers if they are using CircuitPython. This seems like the best solution for this problem so far. Those functions still can’t be used inside interrupt handlers (because they allocate memory to create the floats) and they will introduce additional delays (both for the function call and for creating the float), but it will mostly work.
