# `stm32f103-template`
> Quickly set up a [`probe-run`] + [`defmt`] + [`flip-link`] embedded project
[`probe-run`]: https://crates.io/crates/probe-run
[`defmt`]: https://github.com/knurling-rs/defmt
[`flip-link`]: https://github.com/knurling-rs/flip-link
## Dependencies
#### 1. `flip-link`:
```console
$ cargo install flip-link
```
#### 2. `probe-run`:
``` console
$ # make sure to install v0.2.0 or later
$ cargo install probe-run
```
#### 3. [`cargo-generate`]:
``` console
$ cargo install cargo-generate
```
[`cargo-generate`]: https://crates.io/crates/cargo-generate
## Setup
#### 1. Initialize the project template
``` console
$ cargo generate \
--git ssh://git@gitea.zenerdio.de:2202/sebastian/stm32f103-template.git \
--branch main \
--name my-app
```
