Last night, a student studying abroad asked me about embedded systems. At first, I thought it was a technical exchange, but then he sent me a copy of past exam questions 😂. Upon reviewing, it mainly covered some basic theoretical analyses of real-time systems and some understanding of multitasking code. The main focus was on system design and task scheduling knowledge, corresponding to the embedded systems content for third-year electronics majors in China. It is comparable to the national level three embedded exam questions. Of course, it has more depth than basic microcontroller content. Personally, I think this exam paper is quite reasonable, but without their textbooks, it is difficult to make comparisons in other areas (the chips they use in textbooks should be based on STM32L476. That student asked about the 51 microcontroller L476, but I was confused 😅. Later, I thought he should have been referring to STM’s chips). In the end, I still advised that student to look at textbooks or Google, as the upcoming exam questions may not be the same as this one, and there can be countless ways to ask similar questions about the same topics in embedded systems. If the fundamental concepts are not understood, memorizing answers is meaningless. More importantly, many knowledge points cannot be clearly explained in just a few words.
Editing text on a phone is cumbersome, so I’ll share some images for reference.
