Re: pyboard PWM capable pins...

Your pin selection will be based on what timer you use. See this image for the pins and their corresponding timers http://micropython.org/resources/pybv11-pinout.jpg You use a channel to connect your pin(s) to your timer. For example: ```python timer = pyb.Timer(2, freq=1000) ch2 = timer.channel(2, ...

Re: Sydney MicroPython Meetup

I'm in! I'm going to use the opportunity to attempt to connect my LoPy to the gateway on top of the UTS building. Might go a little early.

Re: Would a pyboard purchase support the project?

Hi all, why micropython on a RPi zero ? To not have the layer raspbian ? thx I was also interested and found this; https://github.com/boochow/micropython-raspberrypi/ Looking a the ref; https://github.com/boochow/micropython-raspberrypi/wiki/Quick-reference-for-the-Raspberry-Pi-Zero---W-MicroPython...

Re: Display PYFLASH of STM32L4R9IDISC in Ubuntu/Window

Weird... you are getting a list of something that's there. What happens when you:

f = open("main.py", "w")
f.close()

Then re-run:

import os
os.listdir()

Perhaps this convo will help someone with more knowledge troubleshoot.

Re: Display PYFLASH of STM32L4R9IDISC in Ubuntu/Window

I'm not an expert at all, but I thought I'd ask.

Are you able to see the micropython interpreter (REPL) with screen or picocom or whatever you use? If so, what happens when you:

import os
os.listdir()

Re: Detecting a beep with ESP32/micropython

I made a fit_sin() function https://github.com/KipCrossing/SpecialMath for one of my projects that might be help. Just set your ADC sample rate to some multiple m of the frequency of the beep frequency and average your buffer into a list of size m for the function. Averaging will help reduce noise. ...

Re: Detecting a beep with ESP32/micropython

Sounds like a fun project. If you know the frequency of the beep, you can use a sin curve fitting function and check if the amplitude > your threshold.
