The layered structure is indeed very useful, and once understood, it can lead to a moment of enlightenment.If I don’t understand how to drive an … Read more
1. Core Definition and Industry Background of Domain Controllers Background of Technological Evolution Pain points of traditional distributed architecture: Each functional module is independently equipped with an ECU (such as engine control, brake control), leading to a surge in the number of ECUs (over 60 in luxury models in 2018), high system complexity, high development … Read more
[Image] Follow us for the latest technology news! [Image]1. Introduction In a computer system, the function of the CPU is to execute programs, which can be summarized as the processes we learn in textbooks: fetching instructions, decoding, and executing. So the question arises, what should the CPU do when there are no programs to execute? … Read more
<Click above Microcontroller and Microcontroller Development Community Follow this public account:)>Introduction:We will adopt the same layered design approach used previously for the button module and display module to design the buzzer module. Similarly, performing layered design on the buzzer module is a good practice that helps provide maintainability and reusability of the code.Below, we will … Read more
