Five Key Considerations in Embedded Microcontroller Programming
During the process of microcontroller programming, if a designer can master multiple programming languages simultaneously, then this designer is certainly a very talented individual. However, it is quite challenging to be proficient in Assembly, C, and C++ at the same time. Many beginners encounter obstacles while learning even one of these languages, leading to frustration. … Read more
Using Switch Statement in C Programming for Microcontrollers
The C language also provides another way for multi-branch selection using the switch statement, which has the general form:switch(expression){ case constant_expression1: statement1; case constant_expression2: statement2; … case constant_expressionn: statementn; default: statementn+1;}The semantics are: calculate the value of the expression. Then compare it one by one with the subsequent constant expression values. When the value of … Read more
Mastering Const in Microcontroller Programming
Click the blue text above Follow us! The const keyword in C is crucial, and today we will delve into the definition and practical applications of const so that it is no longer a mystery. In C, the const keyword is an abbreviation for constant, meaning it remains unchanged. It is usually translated as constant, … Read more
Improving C Language Programming Efficiency: Tips and Methods
Everyone engaged in embedded development writes code in C language. Many people are accustomed to using if and switch, and when defining data structures, they only use character types, integer types, arrays, and bits; rarely utilizing structs, unions, or enums. Today, I will summarize my own set of C programming methods. 1. Clever Use of … Read more
Microcontroller C Language Programming Insights
During the process of writing this 8*8 key program, whether I was writing it myself or referencing others’ programs, I found that I had many misunderstandings about some basic points of C language and programming norms. Some were due to my previous bad programming habits, and some were a manifestation of not having a solid … Read more
How to Improve C Code Readability: Standards and Refactoring Practices
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
Implicit Type Conversion in C Language
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
How to Communicate Between Threads in C Language
First, there is no communication issue between threads within the same process. You can access data however you want; thus, we actually need to do something to actively “isolate” different threads to avoid dirty reads and writes. Second, multi-threaded programming (as well as multi-process programming) requires a foundation in operating systems. Without understanding the operating … Read more
