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.
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
