In embedded system development, choosing a suitable graphical user interface (GUI) library is crucial. When displayed on the screen, using ready-made graphic libraries allows developers to avoid figuring out underlying tasks, such as how to draw pixels, lines, shapes, and if more advanced, create certain objects like windows, buttons, etc. In the previous two issues, … Read more
Understanding MCU Phases 5 and 6 in One Image. Note: MCU Phases 1-3 are “Infinity Saga”; MCU Phases 4-6 are “Multiverse Saga”.
In embedded system development, choosing a suitable GUI library is crucial. When displayed on the screen, using ready-made graphics libraries allows developers to avoid figuring out low-level tasks, such as how to draw pixels, lines, shapes, and, at a higher level, certain objects like windows and buttons. In the first part, we introduced 5 options, … Read more
On Zhihu, there is a classic question that has sparked intense discussion. An engineer found that foreign engineers use for(;;) for infinite loops in demos, instead of the commonly used while(1). Is this merely a matter of personal habit, or is there a deeper significance? No Difference Party: It’s All Psychological Most netizens believe there … Read more
