Serial ports (UART) are a very commonly used interface in embedded systems, but most modern computers lack hardware serial ports. Generally, serial ports are expanded through methods like USB to serial or PCIe bus expansion. USB to serial is a very common solution. Common USB to serial chips include CH340/341, CP2102, and PL2302. However, these … Read more
When we talk about serial ports, we generally refer to UART (Universal Asynchronous Receiver / Transmitter）, the Universal Asynchronous Transceiver. The serial port is one of the most commonly used serial peripherals by engineers, but various issues are often encountered in practical applications. For example: losing one byte of data. Today, we will discuss UART-related … Read more

One Introduction Often, programs run without an operating system, which is known as bare-metal operation and cannot run directly in Linux. Therefore, alternative methods must be used for analysis. Taking a CTF problem as an example, we will learn about analyzing bare-metal programs on the ARM architecture.

Abstract: I heard that many friends learning microcontrollers can’t use structs? Pointers and structs are essential to mastering microcontrollers. If your C language skills are shaky, you won’t grasp the essence of microcontrollers and will only complete some basic projects. Understanding structs and being able to use them flexibly indicates that you have entered the … Read more
