trinket-life

Arduino (trinket m0) implementation of conway's game of life

writeup: https://elibaum.com/2021/02/28/pandemic-projects-tiny-life.html

These files were originally not all in the same place, so I combined into a single git repo. Sorry it's not that well organized. :)

The main and final code is in fast_life_m0, if you want to try it out.

Files

• fast_life_m0 the main project.
• hashdata looking at hashes and game lengths. didn't find much interesting.
• oled_life the original code (for Arduino)
• oled_life_trinket-old the slighly-updated-code for ATtiny Trinket. I never got this fully working - there probably wasn't enough RAM.
• oled_test, rand_test, toggle: testing out various parts of the system individually.
• notes.txt notes from working on this project
• scanned notes.pdf some hand-written notes from when I was trying to work out state machines and various other optimizations.

I didn't have the most up-to-date display library installed! Hence the weird half-screen thing. My OLED test program was working, because I was basing that off of the new version. Super fkin annoying!

Culprit appears to be that the I2C bus wasn't being allowed to send enough data. Fixed here.
