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

Must-Read Books for Beginners in Embedded Arm Linux Recently, a student who just started learning Arm Linux asked me for advice on good books for beginners. Embedded Linux is a vast system that involves hardware and computer science, bridging electronics and computing. Many students from electronics-related majors are unfamiliar with computer principles and operating systems, … Read more
Most applications using Cortex-M3/M4 MCUs are portable and powered by batteries or energy harvesting systems. Therefore, most of the concepts discussed in this article involve how to reduce overall system energy consumption. However, in many cases, these energy-saving technologies are also powerful tools for processor application design, providing more cost-effective solutions, greater design redundancy for … Read more
Author | Robert van der Zwan (Netherlands) Translator | He Mu COVID-19 and MCU: Uncertain Prospects How significant is the impact of COVID-19 on the MCU market? Some research firms have fully considered the effects of the pandemic in their forecasts. Considering the state of embedded systems using microcontrollers (MCUs), they believe the MCU market … Read more
When you want to save the hard drive on your PC, the backup program writes a complete image of the memory contents to a storage medium (such as another hard drive). However, the RevPiCore does not have a hard drive as storage medium. It uses an embedded multimedia card (eMMC) instead of a hard disk … Read more
