Examples

3d graphics demo

output3.mp4

Interactive 3d graphics demo based on embedded-gfx

Use (orange) arrow keys to move, EASD to look around

cargo run --release --bin graphics

Terminal emulator with rink-core

Terminal emulator with rink-core built-in, with a reduced set of (gnu) units so it fits on the ram

You can use it as a simple units-aware calculator

cargo run --release --bin rink

An ESP-NOW receiver with a wifi access point is required
