Started messing with CircuitPython recently and it’s so nice being able to write embedded code in Python. Adafruit’s code library is huge!

I’m starting a new project that needs a lot of I/O so I bolted on an MCP23008. The GPIO was reading inverted from what I expected so I hopped on their discord and someone pointed out the polarity of that chip can be flipped. Sure enough, the library was inadvertently setting the polarity register so I fixed it and sent a PR. Open source is good ya’ll.
