Working principle analysis of PWM in single chip microcomputer

PWM is widely used in single chip microcomputer. Its basic principle is very simple, but it often applies to different occasions, and the meaning is not exactly the same. Here, I will first introduce the basic concepts and basic principles to you, and at least know what it is when it is used later. PWM […]

Comparative analysis of software and hardware between SCM and arm

1. Software 1) Convenient. It is mainly reflected in the later development, that is, the application program is directly developed on the operating system. Unlike MCU, everything has to be rewritten. The early stage of the operating system transplantation work, or to professionals to do. 2) Safety. This is a feature of Linux. The kernel […]
