# 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
|
||
|
