Sipeed MAIX BiT - machine.time_pulse_us

Post by darkglove » Thu Jul 23, 2020 3:14 pm

I wanted to use "machine.time_pulse_us" on a Sipeed MAIX BiT

It seems to newb me that "machine" on these boards have their own set of functions, not the standard micropython ones I've been using on an ESP32.

I think the information I am looking for to recreate "pulseSensor = machine.time_pulse_us(pwPin, HIGH)" is somewhere in

https://maixpy.sipeed.com/en/libs/machine/timer.html

But I'm not really sure

Help appreciated

Sipeed have their own fork of MicroPython and sadly they have implemented their own libraries, which means they have different functionality to the "official" MicroPython. I would imagine that you might be able to use a timer in input capture mode to achieve this, but I don't see input capture in their timer API either.

Thanks again, jimmo

I was going to ask them directly but apart from the online docs and a few posts on here from a couple of years back they don't seem to have much in the way of support.
