Thanks a lot!!!! You save my day (my night in this case).

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...

Why? Can't you always reflash the original firmware through the "Minstorms" Lego app ?
For example you can install Pybricks (https://pybricks.com) and go back to the original firmware as I said.

On the hardware side and quoting: https://antonsmindstorms.com/product/uart-breakout-board-for-spike-and-ev3-openmv-compatible/ LEGO smart hubs have internal resistors that mess with pull-up resistors in the most common i2c devices, so they are hard to connect directly So maybe the problem is also o...

Hi Jimmo, thanks for all your comments, they are welcome!!! >>> dir(machine) ['__class__', 'Timer', 'reset'] Even the Pin class isn't present! 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...

Today I was thinking about I2C implementation I'm missing in lego hubs (Spike or Mindstorms 51515). I mi...
