First, a little aside~ It is said online that the IIC of STM32F103 has flaws! Let’s just consider it as some shortcomings; personally, I think it can definitely be used, but it is not easy to use. Because ST Company considered patent issues, they did not follow Philips’s standards. This leads to the IIC of … Read more
You may have been studying for a long time, but when your leader throws an STM32 project at you, are you still at a loss? A friend of mine started learning the 51 microcontroller and later switched to STM32. He mainly learned by following online courses, typing code along the way. He went through various … Read more
Ways of Communication Between Devices Generally, the communication methods between devices can be divided into parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the direction of data transmission, it can be divided into: Simplex: Data transmission only supports … Read more

It is common to see pull-up and pull-down resistors connected to the D+/D- lines of USB interfaces on some development boards, while others do not connect anything at all. This can be quite confusing. On the official USB protocol website, http://www.usb.org/developers/docs/usb20_docs/#usb20spec I checked the resistor_ecn document. First, the USB bus can have both idle and … Read more
Introduction In embedded development, redirecting printf to the UART serial port is an important means of debugging and logging output. In the Keil environment, the printf function does not directly support UART output for STM32. This article will introduce how to redirect stdout (standard output) to the serial port in the Keil MCU environment, allowing … Read more
I exerted a tremendous effort to finally blow off the STM32H753 with over 200 pins from the PCB using a hot air gun. I breathed a sigh of relief, silently hoping for a miracle. We need to design a new project, and after extensive analysis and consideration, we finally chose the STM32H753 chip. Due to … Read more
SEGGER Embedded Studio (SES) is an integrated development environment that supports application development and debugging for ARM and RISC-V architectures. It also allows for the quick import of projects created with other toolchains, such as Eclipse, CMSIS, Keil, IAR, and CMake. This article will introduce how to import STM32CubeMX projects into Embedded Studio. The example … Read more
