Hi,

I was wondering if I know there is surge of interrupts coming due edge triggering, and I'd like to ignore those for the time being, could I somehow unregister the callback, end register it back later?

So far I only found a way to register callback.

Whoa, I cross compiled mpy-cross, and converted fonts and mopo.py into mpy, and now it starts with bigger font too! Progress, still wondering if I do something wrong adding the two instances of Writer with different fonts at here: https://github.com/ikke-t/mopo/blob/510456a6761e4d6d6a8843f7761d52626...

Thanks, moving imports into Display.__init__() seems to be the right place. I also added the memory debugs. Seems that there is roughly 37kB of memory on the the device, adding together the gc.mem_alloc and gc.mem_free. It loads now if I don't load in the the second font. As soon if I import either ...

So it didn't work until I removed from import from: class Display(): """Output information on SSd1306 oled dis...

The error is somehow related to Display class. If I comment those parts out, and use print() instead, it won't crash.

Hi, I wrote this piece of code that implements small driving computer for moped with originally broken display. It get's speed from hall sensor, and ignition from capacitive wire from spark plug. Before I refactored from my scratch code into cleaner python class code it worked somewhat. But now afte...

Hi, I have been building simple moped computer with my son using micropython on NodeMCU. One of the old boards I had in my box, with esp8266. I had small display on it. But now we'd like to get rid of the display, and use mobile instead. Any recommendations how to create a web page that would pull s...

thanks for confirmation, then I know it's just pylint detecting false errors.
