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.

This tutorial will cover how to get started with FreeRTOS that comes with STM32CubeIDE.

Let’s look at how to connect a simple I2C device to a STM32 Nucleo board to read temperature data using the STM32 HAL API.
