Getting Started with STM32 - Working with ADC and DMA

By ShawnHymel

Let’s take a look at how to use the analog-to-digital converter (ADC) in an STM32 microcontroller. To make conversions happen more quickly, we can use the direct memory access (DMA) controller to pipe data directly from a peripheral (like the ADC) to memory and vice versa.
