Setting breakpoints is a very effective way to debug programs online. Combined with step-by-step debugging, it allows for quick problem identification. However, sometimes manually setting breakpoints can be inconvenient. For example, if you want to stop at the Nth iteration of a loop, you would have to keep clicking step run until the loop reaches … Read more
In AUTOSAR, the SPI module actually divides one SPI communication into many small segments for organization and management. This approach allows for flexible control and easy expansion. Thus, we introduce the following three levels:Channel → Job → Sequence. 1. Channel 👉 Channel is the smallest unit, which can be understood as **”a block of data … Read more

What is the volatile keyword? In embedded programming with C, the volatile keyword is very important. Its English meaning is “changeable”. Its main function is to inform the compiler that the value of the variable it modifies may change in ways that the compiler cannot predict during program execution. Therefore, the compiler cannot perform regular … Read more
