MCS-51 refers to a series of microcontrollers produced by the American company INTEL. This series of microcontrollers includes several varieties, such as 8031, 8051, 8751, 8032, 8052, 8752, etc., among which the 8051 is the earliest and most typical product. When learning about microcontrollers, in addition to understanding the internal functions, memory allocation, and I/O … Read more
The clock circuit is an oscillator that provides a rhythm for the microcontroller. The microcontroller must operate under this rhythm to perform various tasks. Therefore, the microcontroller will not function properly without a clock circuit. The clock circuit itself does not control anything; rather, it is the program that allows the microcontroller to perform corresponding … Read more
Students who are new to the field often ask me a question: Teacher, what does51 microcontroller mean? Today, let’s discuss this topic. 1. Beyond the Model Number 51 originally referred to a classic microcontroller model code from Intel. In the 1980s, Intel launched a series of particularly successful microcontroller products called theMCS-51 series. It can … Read more
Course Introduction: The microcontroller software development platform—Keil software is currently the most popular software for developing MCS-51 series microcontrollers. Keil provides a complete development solution including a C compiler, macro assembler, linker, library management, and a powerful simulation debugger, all integrated into a single development environment (uVision). This tutorial video course on the 51 microcontroller … Read more
Everyone knows that assembly language instructions consist of an opcode and operands. The MCS-51 uses assembly language instructions, which have a total of 44 opcode mnemonics and 33 functions, with operands such as ＃data, direct, Rn, and @Ri. Here, we will first introduce mnemonic symbols for instructions and methods for memorizing them. 1. Mnemonic Symbol … Read more
