1. Introduction 1. The MIPI Alliance, or Mobile Industry Processor Interface Alliance, is an open standard and specification initiated by MIPI for mobile application processors. 2. The MIPI Alliance defines a set of interface standards, standardizing internal interfaces of mobile devices such as cameras, displays, basebands, and RF interfaces, thus increasing design flexibility while reducing … Read more
When we first learn embedded development, a common question arises: what is the difference between C language and embedded C programming? Embedded engineers typically tell you that the difference lies in the fact that embedded C runs on embedded development boards, which differ from CPUs in computers, leading to different compilers and executable programs. Unlike … Read more

1. Registers CM3 has general-purpose registers R0 to R15 and some special function registers. For general-purpose registers R0 to R12, the initial reset values are unpredictable. 2. CM3 has a set of general-purpose registers from R0 to R15. Note: Most 16-bit Thumb instructions can only access R0 to R7, while 32-bit Thumb-2 can access all … Read more
Embedded electronic devices are collections of various circuits (processors or other integrated circuits). In order to exchange information between these independent circuits, they must follow the same communication protocol. To accommodate different needs, engineers have defined hundreds of thousands of communication protocols, which can generally be divided into two categories: parallel or serial. 1. Parallel … Read more
