/blinky-esp8266-rust

Primary LanguageRust

This project uses the esp8266-hal to show you can develop for the ESP8266 in Rust.

Blog post about this project: https://andreas-mausch.de/blog/2024-10-20-esp01s/

Note: esp8266-hal is deprecated and missing important features like WiFi. But I was still interested if this would work at all.

I found a project which does exactly what I am trying to achieve: blinky-esp8266-rust

However, it is a bit dated and uses a esprs/espflash docker image, which is also dated. I prefer to run the compilation without docker on my machine.

So here is my version of it.

Requirements

  • rustup (>= 1.27.1)
  • rust (>= 1.82.0)
  • cargo (>= 1.82.0)
  • cargo-espflash (exactly 2.1.0) Can be installed via cargo binstall cargo-espflash@2.1.0
  • Rust xtensa-lx106 toolchain Can be installed via espup install --toolchain-version 1.80.0.0

Note: Newer versions might not have esp8266 support, see here: Support for xtensa-esp8266-none-elf removed in 1.81

cargo-espflash has removed support for the ESP8266, see here: RFC: Remove support for ESP8266

Build

Make sure to source the esp toolchain:

source ~/export-esp.sh
cargo build
# or:
cargo build --release

Flash to ESP-01S

cargo espflash flash --baud=115200 --flash-mode=qio --flash-freq=40mhz --flash-size=1mb --port=/dev/ttyUSB1 --release --monitor
