Re: I2C in new lego hubs [STM32]
Hi Jimmo, Hi others Sorry to insist, but now I see that v1.17 supports Lego hub. I want to be sure that I can install it and revert to original Lego firmware. I don't see any reason why it shouldn't be the case, but your last message saying "you lose the ability to go back to the factory Lego firmwa...

Thanks Jimmo, that's fine!
For example you can install Pybricks (https://pybricks.com) and go back to the original firmware as I said.
Why? Can't you always reflash the original firmware through the "Minstorms" Lego app ?you lose the ability to go back to the factory Lego firmware

But if I build and install latest firmware, which would be great, I guess I would loose all the Lego functions and libraries? The logic behind this is that t...

I2C in new lego hubs [STM32]
Hi While I have been using micropython in various platforms (ESP32, ESP8266, STM32 with Lego new hubs), I'm new in trying to compile my own version of micropython or even some specific libraries. Today I was thinking about I2C implementation I'm missing in lego hubs (Spike or Mindstorms 51515). I mi...
