How to keep your app running continuously? By default, if no cross-process deployment configuration is made, each Android app runs in a separate virtual machine, with each virtual machine corresponding to a process. When the app is reclaimed by the system or actively killed by the user (through app management software), the process exits completely. … Read more
In most cases, application code can be written in C or other high-level languages. However, having a basic understanding of the instruction set supported by Cortex-M processors helps developers choose the right Cortex-M processor for specific applications. The instruction set (ISA) is part of the processor architecture, and Cortex-M processors can be divided into several … Read more
Sitting on the high-speed train from Shanghai to Beijing, the long journey really makes one feel bored (I couldn’t get a direct train, so I can only go slowly, stopping at every station. It’s ridiculous that in the high-speed train era, it still is like this. It reminds me of the time in college when … Read more
