Rust on Tessel
Rust is a new systems programming language emphasizing safety, concurrency, and speed. It requires no runtime, so it's suitable to use as a better C for microcontroller development. This is a simple demo running Rust on bare metal on a Tessel, which uses a NXP LPC1800 microcontroller with an ARM Cortex M3 core.
The standard Rust compiler is capable of cross-compiling for ARM. See the Rust Guide for installation instructions, as well as learning the language.
You'll also need a copy of gcc-arm-embedded. We won't use its C compiler, but it includes an assembler, linker, and binutils.
Clone this repository:
git clone https://github.com/kevinmehall/rust-tessel cd rust-tessel
You need a copy of Rust's
libcore compiled for ARM, so clone the
rust repository and build the library:
git clone https://github.com/rust-lang/rust rustc -O --target=thumbv7m-linux-eabi rust/src/libcore/lib.rs
I've wrapped the commands to compile, link, and produce a binary image into
Use the Tessel bootloader to run the executable:
tessel boot blinky.bin
It runs from RAM, so press the Reset button to return to normal Tessel firmware.
