Makerfaire Ottawa: Rule 110 (2015)
Wooohoo! I can now officially cross something off my bucket list:
I tried to write my own driver for the display in C for the Propeller, but I had some serious flickering issues that I wasn’t able to fix… Given that I didn’t want to give everyone at makerfaire a headache / induce seizures I chose to use this library from Adafruit. Each input pin on each of the shift registers has a pull down resistor in order to deal with electrical gremlins, and also to make my assembly time much much longer. Writing this was a fun excersise to see how well I understand arrays / pointers in C. It turns out I still don’t grok them, but with sufficient sacrifices to Malloc (all praise to It), I managed to get things working.
