building lighting system real-time monitoring. The Coordinator is responsible for establishing, managing and maintaining the network, receiving the information of each routing node, and then sending the data to the computer through the serial port, displaying the real-time situation in the computer terminal and transmitting the control command. The routing node has the functions of terminal control, information acquisition and automatic alarm. 2.2 Hardware Design The classroom node is mainly co

the first letter of the two people, a, V, and A, which is not officially recognized by ATMEL ). I think it's the most cost-effective version of the mega Series. Originally, it was uncomfortable for Xiao Zhu to switch the developed hardware platform when he was a little familiar with the 80C51 series. Discard familiar tools such as Keil and serial download tool to get familiar with new tools. Xiao Zhu started the mix project with such emotions. The configuration of the AVR series microcontr

-EndianA computer architecture in which, within a given multi-byte numericRepresentation, the most significant byte has the lowest address (Word is stored "big-end-First ").Most processors, including the IBM 370 family, the PDP-10,Motorola microprocessor families, and most of the various RISC DesignsCurrent in mid-1993, are big-Endian. [from: free on-line DictionaryComputing or jargon file]Big-Endian: a term in the computer architecture that describes

microprocessor (CPU) and memory, but also I/O interface (I/O interface) and peripherals. Therefore, it is actually a card-based microcomputer, or a veritable minimum computer terminal. Because of its powerful function, this kind of card has great development potential. However, due to the difficulty and high cost of the card manufacturing technology, it is not popular at present.Intelligent IC Card The so-called Intelligent IC Card is in the IC card

BusyBox, I keep valuable resources and save a lot of time investment. I cannot find other tool sets like this. 　　 　　 Components and preparations To continue, you need to have the right to use an existing Linux system-it is better that the microprocessor used to run the system is the same series as that of your target system. An older Linux-running portable computer is an excellent environment for writing and editing, but it cannot compete with modern

2.1 Memory Address Three different addresses for 80x86 microprocessors: Logical address: The address used to specify an operand or an instruction in a machine language instruction Each logical address has a segment and offset, which indicates the distance between the point where the segment starts and the actual address. Linear address: Also becomes a virtual address, is a 32-bit unsigned integer that can be used to represent addresses up to 4G

Arm+linux route, focuses on embedded Linux operating system and its application software development goals:(1) Master the structure and principle of the mainstream embedded microprocessor (initially set as ARM9)(2) must master an embedded operating system (initially set to Uclinux or Linux, version tbd)(3) must be familiar with the embedded software development process and at least one embedded software project.The benefits of engaging in embedded sof

The CPU (central processing Unit, CPU) developed three branches, one is the DSP (digital Signal processing/processor, signal processing), the other two are MCU (Micro Control Unit, microcontroller unit) and MPU (Micro Processor Unit, microprocessor unit).MCU integrates the on-chip peripheral devices, MPU without peripheral devices (such as memory array), is a

important thing is that the computer is making progress too fast. The top-level Configuration computer purchased in the past two years is still a trivial matter, even more cool, it seems that we need to learn new knowledge every day. When we first graduated, we only learned Pascal from books and learned to use corrosion methods to make circuit boards. At work, we started to learn turboc and tanger2.0, I have just learned how to learn Borland C ++ and protel3.0 before I can be happy, but I learn

Does your system need linux? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Allen's World I have worked on several products. They use different processors, such as 80186, z80 (old enough), and arm7. All of them use a certain RTOS. In addition to the ecos used in the product 7.7, the other two RTOS are very small systems. They only provide the most basic kernel for multi-task proce

designers to find a FAT open source file system that is easy to transplant and use, occupies relatively small hardware resources, and has powerful functions. FatFs Module is a completely free and open-source FAT file system Module designed specifically for small embedded systems. It is fully written in standard C language, so it has good hardware platform independence, it can be transplanted to the 8051, PIC, AVR, SH, Z80, H8, ARM and other series of
