Follow the Embedded Learning Station to get more fresh hot topics. Before discussing the learning path, let’s first understand what embedded development is. Simply put, an embedded system consists of two parts: software and hardware. It is application-centered and can achieve software and hardware tailoring. Software includes: specific business applications and operating systems (simple applications … Read more
If a large embedded project does not implement fault tolerance design, can you imagine what the consequences would be? Experienced friends can certainly think of countless bugs in such projects, and some bugs are very difficult to trace. Today, let’s discuss some common fault tolerance design methods in embedded code. Using Assertions (Assert) What is … Read more
After working for a few years, I often see some friends asking whether design patterns need to be learned. It seems that those who work in embedded systems have never encountered the need to use design patterns, so they have never systematically studied them. However, I know that design patterns are important, yet over time, … Read more
