ARM IAP upgrade method

Two places are worth noting: (1) Interrupt vector mapping (2) The user program Ro_base setting is consistent with the address to be downloaded, That is to say, to download the same program to FLASH with different addresses, you must first set the corresponding Ro_base address of the program under KEIL, genera

Six prerequisites for ubiquitous computing

Building an ecosystem for ubiquitous computing and integrating computing into everyday things will require a lot of trial and error. There is no doubt that digital technology will become more and more common in the coming decades. Organizations such as Exponential Group believe that digitalization should be the fir

ARM CMSIS Driver Learning SPI

CMSIS Driver has similar API functions and similar calling methods. It is a further encapsulation based on the ST HAL library. It is much more convenient and simpler to use and configure than the ST HAL library. It is also cross-platform and very valuable to learn and use. Today we will learn how to use the SPI API. F

Design of intelligent apartment security measurement and control system based on ARM

Looking at the current status of campus security, it is not optimistic for both colleges and universities and primary and secondary schools. The theft of students' belongings in school dormitories and fires caused by students' improper use of electrical appliances are "big problems" in college management. With the a
