GPIO (General Purpose Input/Output) is a pin on a microcontroller or microprocessor that can be programmed as an input or output for communication with external devices. In Linux systems, developers can easily read and set the state of GPIO through user space interfaces provided by the kernel, enabling control and monitoring of external devices. This … Read more
Getting Started: Bare-Metal Programming on ARM Cortex-M Microcontrollers Bare-metal programming typically refers to the process of writing programs to control hardware devices directly without an operating system. For embedded system developers, this is a fundamental and important skill. Today, I will guide you through how to implement bare-metal programming on ARM Cortex-M series microcontrollers. Starting … Read more
Hello everyone, I am Pi Zi Heng, a serious technical person. Today, I will share with you the Cortex-M System Interrupt Latency and Measurement Methods. In the embedded field, real-time performance is a concept we often emphasize. Here, real-time performance mainly emphasizes whether the system can respond within a specified time frame when external events … Read more
Scan to FollowLearn Embedded Together, learn and grow together There is a very popular question on Zhihu — “What are the advanced uses of MCUs?“ It is said that MCUs themselves are not particularly advanced, but during the MCU development process, certain standardizations must be followed, such as defining variables and functions, determining their lifecycle, … Read more

Light Up an LED Overview The purpose of this tutorial is to light up an LED using a program, which will automatically turn off after 3 seconds. In all programming languages, the first program is called hello world, and today’s LED lighting tutorial is essentially the hello world of hardware programming, making it a very … Read more
The manual porting process is complex and tedious. First, use cubemx for quick configuration: First, print a message to the serial port: /* USER CODE BEGIN 2 */ printf("hello shxi\r\n"); /* USER CODE END 2 */ /* Call init function for freertos objects (in freertos.c) */ MX_FREERTOS_Init(); OK proves that the configuration is correct! Tasks … Read more
