> 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
|
||||
```
