STM32 Blue Pill SPI communication STM32CubeIDE

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

esp32 spi communication tutorial with Arduino IDE

In this tutorial, we will learn to use SPI communication buses of ESP32. By using that, we will see how to perform master slave SPI communication with ESP32 boards using Arduino IDE. Furthermore, we will look into SPI pins, how to use multiple SPI bus interfaces supported by ESP32, and how to configure them. Recommended … Read more
