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

Summary of C51 Microcontroller Programming Points 1. Header file: #include (I am using STC 89C54RD+) 2. Pre-definition: sbit LED = P1^0 // Define bit 0 of port P1 as LED Note: The notation “P1^0” is different from A51 (A51 uses P1.0). P1 is a group of ports, and the port number ranges from 0 to … Read more
It is said that learning microcontrollers involves four stages: 1. Beginner Stage: Understand the basic concepts of microcontrollers and their application areas, master basic electronics knowledge and programming knowledge. 2. Entry Stage: Choose the appropriate microcontroller and development board, set up the development environment, and conduct basic practice projects such as LED blinking and button … Read more

What is a Robot Control System? Having only sensors and muscles is not enough for human limbs to move. On one hand, sensory signals need organs to receive and process them; on the other hand, there are no organs to send neural signals that drive muscle contraction or relaxation. Similarly, if a robot only has … Read more

The root filesystem is the first one that must be mounted during Linux startup; if the system cannot mount the root filesystem from the specified device, it will fail to start.Other filesystems can then be mounted automatically or manually. Therefore, different filesystems can coexist within a system.Different types of filesystems have different characteristics, thus they … Read more
Word Count:4500 Content Index:⭐⭐⭐⭐⭐ Concept of Linux Device Driver System calls are the interface between the operating system kernel and application programs, while device drivers serve as the interface between the operating system kernel and machine hardware. Device drivers abstract hardware details from application programs, allowing them to interact with hardware devices as if they … Read more
