Question about pin assignments

[ril3y]

Sorry as I did not see a place to ask questions. I am curious about why only 9 gpio are used? There are more pins available. This is more than likely a dumb question but looking over the code I was not seeing why this would be. Thanks for indulging the question!

Hi ril3y,

That's a great question! It was purely a design choice considering there are now too many variants of dev boards with this micro-controller & is definitely not a hardware limitation. Feel free to increase this if required for your use-case.

Thanks I appreciate it! I wasn't sure I was just missing something obvious. I am planning on expanding it to 16 channels. Thanks!
