Re: mpy-cross not making files smaller
There was a change in the mpy file format recently. Please ensure, that both mpy-cross and the firmware come from the same build. Thanks! This did it for me! I'd still recommend burning your code to an image, if you want to really keep the memory image down. For large applications, I have found tha...

My main.py is so long it can only be imported by commenting out some lines (that are not even called by the code unless speci...
