libtock-rs

Rust userland library for Tock (WIP)

Tested with tock a3b36d5872315ff05ef5ad34ed9453b0789218ce.

Getting Started

This project is nascent and still under heavy development, but first steps:

Ensure you have rustup installed.

Clone the repository.

git clone https://github.com/tock/libtock-rs
cd libtock-rs

Install elf2tab.

cargo install -f elf2tab --version 0.4.0

Add dependencies for cross-compilation.
```
rustup target add thumbv7em-none-eabi
```
Use the run_example script to compile and run the example app you want to use:
```
./run_example.sh blink
```
This should work if you are using the nRF52-DK platform. For other platforms, you will end up with a TAB file in target/tab that you can program onto your Tock board (e.g. with tockloader install target/tab/blink.tab).

Using libtock-rs

The easiest way to start using libtock-rs is adding an example to the examples folder. The boiler plate code you would write is

#![no_std]

extern crate tock;

fn main() {
  // Your code
}

If you want to use heap based allocation you will have to add

#![feature(alloc)]
extern crate alloc;

to the preamble.

To run on the code on your board you can use

./run_example.sh <your app>

This script does the following steps for you:

cross-compile your program
create a TAB (tock application bundle)
if you have a nRF52-DK board connected: flash this TAB to your board (using tockloader)
