requirements

• The Espressif Rust toolchain via espup (this repo pins channel = "esp" in rust-toolchain.toml).
• espflash for flashing/monitoring (the cargo runner is preconfigured in .cargo/config.toml).
• Optional: just for the convenience recipes.

The cargo runner flashes and opens the serial monitor, so cargo run … builds, flashes the connected board, and tails its output.

just clock   # flash the wifi clock example          (t5s3-epaper-core)
just ui      # flash the touchscreen ui              (t5s3-epaper-ui)
just ble     # flash the ble ⇄ lora bridge example   (t3s3-epaper)
just check   # compile-check the whole workspace
just lint    # fmt + clippy across the workspace
