# Starting a new project

Now that you have learned about the main features of the RTFM framework you can
try it out on your hardware by following these instructions.

1. Instantiate the [`cortex-m-quickstart`] template.

[`cortex-m-quickstart`]: https://github.com/rust-embedded/cortex-m-quickstart#cortex-m-quickstart

``` console
$ # for example using `cargo-generate`
$ cargo generate \
    --git https://github.com/rust-embedded/cortex-m-quickstart \
    --name app

$ # follow the rest of the instructions
```

2. Add a peripheral access crate (PAC) that was generated using [`svd2rust`]
   **v0.14.x**, or a board support crate that depends on one such PAC as a
   dependency. Make sure that the `rt` feature of the crate is enabled.

[`svd2rust`]: https://crates.io/crates/svd2rust

In this example, I'll use the [`lm3s6965`] device crate. This device crate
doesn't have an `rt` Cargo feature; that feature is always enabled.

[`lm3s6965`]: https://crates.io/crates/lm3s6965

This device crate provides a linker script with the memory layout of the target
device so `memory.x` and `build.rs` need to be removed.

``` console
$ cargo add lm3s6965 --vers 0.1.3

$ rm memory.x build.rs
```

3. Add the `cortex-m-rtfm` crate as a dependency.

``` console
$ cargo add cortex-m-rtfm --allow-prerelease
```

4. Write your RTFM application.

Here I'll use the `init` example from the `cortex-m-rtfm` crate.

``` console
$ curl \
    -L https://github.com/rtfm-rs/cortex-m-rtfm/raw/v0.5.0-beta.1/examples/init.rs \
    > src/main.rs
```

That example depends on the `panic-semihosting` crate:

``` console
$ cargo add panic-semihosting
```

5. Build it, flash it and run it.

``` console
$ # NOTE: I have uncommented the `runner` option in `.cargo/config`
$ cargo run
{{#include ../../../../ci/expected/init.run}}```
