# STM32F411CEU6 ADC example 
Working example to work with the internal ADC of the STM32F411CEU6 present on a Blackpill board.  

The `#init` task configures the ADC module for single-shot conversion and `PA1` as analog pin.  

Afterwards, the analog pin stored in a Potentiometer struct is set as a **local** resource to the hardware task associated to `EXTI0`.  

The `Adc<ADC1>` instance on the other hand, is set as a **shared** resource. The reason behind this approach is to allow other tasks make use of the only ADC module present on this microcontroller.  



## How-to

### Build
Run `cargo build --release` to compile the code. If you run it for the first time, it will take some time to download and compile dependencies.

### Run
Install `probe-rs` and configure it using the [debugging extension for VScode](https://probe.rs/docs/tools/debugger/).  
The output should look like this:

```
INFO Current delay value 1900
INFO Current ADC value 665

INFO Current delay value 1800
INFO Current ADC value 1138

INFO Current delay value 1700
INFO Current ADC value 1136

INFO Current delay value 1600
INFO Current ADC value 811

INFO Current delay value 1500
INFO Current ADC value 1752
```
