See # 5514 for an alternative way to generate a sine wave using extra features of the ESP32 DAC. Note that this is a non-standard MicroPython feature (since it's quite particular to the ESP32) and my guess is that it's unlikely to be merged. An alternative that might have a better chance would be to...

The company I work for uses MicroPython commercially to build medical devices . We have a handful of successful projects that have been completed over the past 4-5 years. Andrew, a colleague and friend, gave a talk at the 2019 PyCon AU: Profiling Pathogens with (micro) Python . While we've completed...

Take a look at mpy-cross v1.17 on PyPi.
You'll also find basic documentation on how to use it on that page. Basic use:

mpremote is OS independent but it requires pyserial which is a little more picky...maybe first try 'pip install pyserial' and see if that works?

See forum thread MicroPython version 1.18 released, including PR 8200 from Roberthh which ought to address your issue.

As Robert mentioned, PR #7817 added improved support for ESP32 PWM. It was merged on the 21st September (ie after v1.17) so, for now, you'll need to pick up a nightly build.

v1.18 - containing this change - should be released soon!

As an aside...for a long time, Damien has been considering changing to the 1970 the epoch - for all ports - bringing it in-line with CPython (rather than the year 2000). It's a complex topic and, since it will be a breaking change, has to be very carefully considered. Some discussion is in #5969.

Hi Peter, I don't need it right now but at some point in the future, I will wish I did. I don't want to ask you to do more work but yes, I'm interested in it.

It's really impressive stuff, thanks for your efforts Julie! I discussed Wokwi briefly at the November Melbourne MicroPython Meetup ( Slide 25 ) and there was certainly interest in it. I also enjoyed Uri Shaked's recent Remoticon talk about extending the Wokwi simulator by Reverse Engineering the ES...

What about machine.SoftSPI? This should work.

Oh, that's a much better idea!

May not be able to achieve 2MHz with SoftSPI (anyone know the max actual baud rate?) but at least it will be functional.
