Re: machine.RTC documentation

The Pyboard predates the machine API definitions; back in the day it used the original pyb API (machine evolved to be more platform agnostic than pyb). While many of the machine API's are now available on the pyboard, RTC is only half-way there. Effectively, pyb.RTC has just been aliased to machine....

Re: NXP HCS12 Port

It seems that chip has just 12KB of RAM; that'll be the biggest stumbling block. Technically it may be possible to get MicroPython running on that hardware - but it will take a lot of effort and require significant compromise (drop the compiler, REPL etc). The smaller micros that run MicroPython use...

Re: ESP-32 WROOM discrepancy in quickref page

Thanks for raising this @albtrentadue. If we can get a definitive answer I'm happy to make the change to the docs; I'm guilty of writing the confusing original! I've created issue #7068 ESP32 Quickref pin guidance should be improved . But please continue to discuss and share your findings (here or i...

Re: GSoD

We intend to apply, yes. We can hopefully leverage our proposal from 2020.

I was going to update the proposal but if you - or anyone else! - are motivated to be involved please let me know. Jim and I were mentors last year and it would be great if we could share the load around the community.

Re: Help me build micropython esp32!

Please submit console output as to where your failure has occurred so we can help diagnose the problem. It's worth noting that the fork you're using is pre-v1.14 where there was a change in the ESP32 build process (to use CMake). These changes simplified the build process, so you may find it benefic...

Re: STM32WL - 1st microcontroller SoC with LoRa

Any news about MicroPython port efforts for STM32WL family ? Nothing official yet (but I know that Damien has booted a REPL on the Nucleo WL55!). I've already ordered one each of the dev kit and the mini - those Seeed boards looked interesting! And, yes, I was able to purchase a JC1 a month or two ...

Re: STM32G474xx on NUCLEO-G474RE

Hey RealSparky,

I have one of the NUCLEO-G474RE boards; I'm keen to see that port progress! If you'd like me to review or test anything please let me know...

Cheers,

Re: number of PWM channels on esp32 wroom

This is a known limitation of the ESP32 port - MicroPython is not currently exposing all of the PWM capabilities of the ESP32. The ESP32 port is intended to receive more attention in the next release and adding better PWM support is a common request so I think there's a good chance this will be addr...

January 2021 Melbourne MicroPython Meetup (RPi Pico)

Hi folks,

I've put the recordings of the January 2021 Melbourne MicroPython Meetup online. I give my usual news update but, more importantly, Damien gave an interesting talk about the Raspberry Pi Pico port! Pretty cool stuff. :)

Enjoy!

Re: Wifi bridge for RPI Pico

You could try leveraging the work Adafruit have put into their ESP32-based Airlift wifi co-processor . Basically, run some Arduino-based firmware on the ESP32 , connect it to your micro over SPI and then, the tricky part, write a module to route wifi requests over SPI. You could try porting the Circ...
