pico-conway

Cellular automata on a pico...

Cells are colour-coded according to their age. Button A resets, B clears the screen, X adds a randomly-placed glider (this happens randomly without pressing anything). Y toggles screen brightness.

build the image with

mkdir -p build
cd build
cmake ..
make -j

copy image to device (connected with BOOTSEL pressed), e.g.
```

```

test

The algorithm itself can be tested/debugged on the host machine using the test harness, e.g.:

g++ -g -O0 -Wall -Werror --std=c++20 src/test_conway.cpp src/conway.cpp -o test
