Installation Instructions

The following instructions were taken from https://github.com/esp-rs/rust-build#rust-build.

Using Rust for ESP32

Step 0: install Rust & Cargo from RustUp

• Go to https://rustup.rs/

Step 1: Install espup

cargo install espup
espup install # To install Espressif Rust ecosystem
# [Unix]: Source the following file in every terminal before building a project
. $HOME/export-esp.sh

Step 2: RISC-V Installation

rustup target add riscv32imc-unknown-none-elf

Step 3: The Cargo First Approach

cargo install cargo-generate

# STD Project
cargo generate esp-rs/esp-idf-template cargo
# NO-STD (Bare-metal) Project
cargo generate esp-rs/esp-template

cargo espflash flash <SERIAL>
# for me, this was cargo espflash flash --port /dev/ttyUSB0 

Internal Blink project

The standard sanity check after creating a new project is to create a project that blinks the internal led.

See main.rs for the sample code.
