Introduction A microcontroller, also known as a microcontroller unit (MCU), integrates a complete computer system, including the CPU, RAM, ROM, timers/counters, and various I/O interfaces, onto a single chip. Due to its numerous advantages and characteristics, the applications of microcontrollers are extremely wide-ranging. A microcontroller system consists of both hardware and software systems, which involves … Read more
I am an embedded developer who has worked on various models of microcontrollers and embedded systems. Sometimes, I often look at programs written by others and frequently find many issues in the details. Although the functionalities achieved are the same, the stability can vary. I would like to discuss some problems I have observed for … Read more
In today’s era, new technologies are emerging one after another. In the field of electronics, especially in automation and intelligent control, traditional control systems made of discrete components or digital logic circuits are being replaced at an unprecedented speed by microcontroller-based intelligent control systems. Most higher engineering schools have already introduced microcontroller courses. Microcontrollers have … Read more
/*** Direct Hit to the Essence ***/ 1) A certain time delay is required when powering up the entire chip The main reason is that during the power-up process, the power supply is not stable enough, which may interfere with the internal initialization of the chip, causing abnormal operation of peripheral devices; at the same … Read more
Have you heard this joke? A programmer walks into a bar and says to the bartender, “Can I get a beer? And add a while(1)?”The bartender is puzzled: “Do you want me to create an infinite loop?”The programmer laughs and says, “No, boss, I just want a drink that never ends.” As you can see, … Read more
1.1 Definition Implicit type conversion, also known as automatic type conversion, is performed automatically by the compiler during the compilation process, without the need for the programmer to explicitly perform operations. 1.2 Type Conversion in Arithmetic Operations 1.2.1 Definition When values of different types participate in arithmetic operations, the compiler promotes the operand of the … Read more
