Introduction Having been involved in embedded software development for nearly five years, I have predominantly used microcontrollers from the ARM Cortex M series. During this period, I have been grateful for the presence of C language compilers, which allowed me to develop without needing to delve into assembly language. However, I feel I have missed … Read more
As we all know, ARM has launched three series of CPUs: 1）The Cortex-M (Microcontroller) series is aimed at embedded systems and microcontrollers, used in IoT devices, sensors, and consumer electronics; 2）The Cortex-A (Application) series has high performance, multi-core processing capabilities, and supports complex operating systems, used in smartphones, tablets, and high-end embedded systems; 3）The Cortex-R … Read more
