Understanding SPI Communication Between STM32 and ESP32 (Using Two Different Chips for Inter-Board SPI Implementation)

Friends, recently I needed to use SPI communication, so I used two boards, the STM32F03C8T6 and the ESP32, to implement SPI communication between them. Here, the STM32 acts as the SPI master, using the STM32 standard library functions. The ESP32 acts as the SPI slave, using the ESP-IDF spi_slave driver.P.S. I searched online for a … Read more

How to Print Logs from STM32 Microcontroller Without Using Serial Port

This article mainly introduces methods for outputting logs in embedded development. The most common method is to output UART logs through the serial port. This method is simple to implement, and most embedded chips have serial port functionality. Related articles: Learning STM32 Microcontroller, Serial Port is Inevitable. However, such a simple function can sometimes be … Read more

The Importance of Using the Static Modifier in Embedded Development

In embedded development, adding the <span>static</span> modifier before variables and functions is a very important practice that primarily serves three core purposes: limiting scope, extending lifespan, and controlling memory allocation. This is particularly crucial for resource-constrained embedded systems that require high reliability. Here is a detailed explanation: 1. Using <span>static</span> for Variables a) Static Local … Read more
