Mozilla RustThe official team provides an extensive and high-quality eBook and technical documentation, which is enough for us to read directly.Moreover, I guarantee you won’t finish it because they are continuously updated with newrust versions, and occasionally there are new books on specific topics (for example, async programming, macros, cargo book, rustc book, etc.).I feel … Read more
Linux | Red Hat Certified | IT Technology | Operations Engineer 👇 Join the 1000-person technical communication QQ group. Note: [Public Account] for faster approval 1. Basic Concepts Environment variables (environment variables) generally refer to parameters used to specify the operating environment of the operating system. For example: when we write C/C++ code, we never … Read more
Graphic Control Uncle Composition conveys ideas Reading has never been this easy!!! 01 Introduction When developing multifunctional applications for an LCD screen, there are times when you need to clear the screen. Clearing can be done in two ways: full screen clear and partial screen clear. Today, I will document the code for partial screen … Read more
MCU stands for Microcontroller Unit, which is commonly known as a single-chip microcontroller. It reduces the CPU’s frequency and specifications appropriately and integrates memory, counters, USB, A/D conversion, UART, PLC, DMA, and other peripheral interfaces, even LCD driver circuits, into a single chip, forming a chip-level computer. This allows for different combinations of control for … Read more
Frame The UART communication standard uses an 8-bit binary number as a frame, with the least significant bit first, transmitted bit by bit. To distinguish each frame, a 0 is used as a start marker before each frame, followed by a 1 as a stop marker. Before the stop marker, an optional “parity bit” can … Read more
Combining the key input program, we designed a functional program: Pressing the number keys 1 to 9 controls the motor to rotate 1 to 9 circles; using the up and down keys changes the rotation direction, pressing the up key rotates forward 1 to 9 circles, while the down key rotates backward 1 to 9 … Read more
When starting to learn about embedded systems or microcontroller systems, most people’s learning method is to find video tutorials or books to learn by themselves. Some may spend money to enroll in a training class to learn with a teacher. When you slowly become capable of writing code independently, you might feel like you have … Read more
This article mainly shares an open-source management module that helps achieve layered management of applications and hardware in an MCU project. Nowadays, project requirements are more complex, which naturally imposes stricter demands than before. From a technical perspective, I still recommend that everyone should maintain a layered structure (application and driver) in their projects. This … Read more
This Session’s Learning Implementing Two Lines of Different Content on LCD Using Code Knowledge Points for This Session: Understand how to achieve a two-line display effect on the LCD (the last learning session of microcontrollers this semester) Learning Tools: Computer, Keil uVision4 software, Proteus software Microcontroller Explanation After several weeks of studying microcontrollers, I believe … Read more
Introduction Microcontrollers are quite “low-level” and “hardware” components, lacking complex data structures and intricate programming algorithms. We only need to understand and program from the perspective of how the microcontroller executes. For the average person, there is no need to delve deeply into the subject, as most of us are merely users of microcontrollers, not … Read more
