esp-template

opinionated bare-metal async Rust template for the ESP32-C3/C6, or about 650 lines of code I was going to write anyway.

portability

this template can be built for both the ESP32-C3 and ESP32-C6:

• use just r3 or just r6 to flash and monitor.
• use just b3 or just r6 to build.
• use just c3 or just c6 to run Clippy.
• use just bl3 or just bl6 to run cargo-bloat.

the Justfile recipes automatically set the required build target and crate features.

Nix

the Nix flake exports a dev shell, some checks, and 2 packages, one per target.

the dev shell contains common utilities for development: the Rust toolchain, cargo-binutils, cargo-bloat, espflash, esptool, and just.

building the package generates an ELF binary and a flat firmware image, the latter of which can be flashed onto a module.
