In this STM32 Nucleo tutorial, we will learn to use ADC and read analog input voltage using STM32CubeIDE and HAL libraries. We will discuss three methods to read ADC including polling, interrupt, and DMA method. This will be demonstrated with the help of an LED dimmer example where we will connect the potentiometer as an … Read more
In this tutorial, we will show you how to use STM32 Nucleo UART with DMA to transmit and receive data through direct memory access without requiring to involve CPU. In DMA mode, data can be transferred from UART RX data register to user memory without any CPU processing time. By using DMA with UART, we … Read more
In this STM32 Blue Pill tutorial, we introduction of DMA direct memory access controller of STM32 microcontrollers. We will discuss the hardware and features of the DMA unit, how to configure and use it and its applications. Recommended Components The following components are used in this project or are helpful for getting started with STM32 … Read more
In this STM32 Blue Pill user guide, we will learn how to send and receive data through SPI communication protocol between a master STM32 and a slave STM32 board. We will particularly focus on showing you three methods to receive data via SPI communication that involves polling, DMA, and interrupt methods. Therefore, we will create … Read more
