# STM32F103 Bluepill RTIC Blink example
|
||
|
|
|
||
|
|
Working example of simple LED blinking application for popular Bluepill boards based on the STM32F103C8 chip. Example uses schedule API and peripherials access. You will need `stlink v2` tool or other programmer to flash the board.
|
||
|
|
|
||
|
|
## How-to
|
||
|
|
|
||
|
|
### Terminal workflow
|
||
|
|
|
||
|
|
Rust embedded relies heavily on `terminal workflow`, you will enter commands in the terminal. This can be strange at first, but this enables usage of great things like continious integration tools.
|
||
|
|
|
||
|
|
For Mac OS X consider using `iTerm2` instead of Terminal application.
|
||
|
|
For Windows consider using `powershell` (win + r -> powershell -> enter -> cd examples\stm3f1_bluepill_blinky)
|
||
|
|
|
||
|
|
### Build
|
||
|
|
|
||
|
|
Run `cargo build` to compile the code. If you run it for the first time, it will take some time to download and compile dependencies. After that, you will see comething like:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ cargo build
|
||
|
|
Finished dev [optimized + debuginfo] target(s) in 0.10s
|
||
|
|
```
|
||
|

|
### Connect the board
|
||
|
|
|
||
|
|
You need to connect you bluepill board to ST-Link and connect pins:
|
||
|
|
|
||
|
|
| BOARD | | ST-LINK |
|
||
|
|
|-------|----|---------|
|
||
|
|
| GND | -> | GND |
|
||
|
|
| 3.3V | -> | 3.3V |
|
||
|
|
| SWCLK | -> | SWCLK |
|
||
|
|
| SWDIO | -> | SWDIO |
|
||
|
|
|
||
|
|
Plug in ST-Link to USB port and wait it to initialize.
|
||
|
|
|
||
|
|
### Flashing and running
|
||
|
|
|
||
|
|
Install `cargo embed` from probe-rs tools by following the instructions at https://probe.rs/docs/getting-started/installation/.
|
||
|
|
Flashing with a standard STLink v2 is easy with `cargo-embed`:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ cargo embed --release
|
||
|
|
```
