Introduction8051 Core SCM is a universal monolithic microcomputer, which occupies a large market share in China. Keil has been the most successful in the study of the use of C language for 51-core microcontroller. Due to the particularity of the storage structure of the 51-core microcontroller, the use of variables in Keil C51 differs from standard C. The correct use of variables facilitates the acquisition

Time -sharing of external extended address data bus with single chip microcomputerZz:http://doc.qkzz.net/article/7c2c3384-6ae9-49b2-8f56-200d87c1830a.htm 0 Share:-Li Ling "Abstract" This paper analyzes the bus timing of the external expansion of single-chip microcomputer, puts forward the problem of time-sharing of address and data bus when the system is connected by bus, and illustrates the design method of data address bus circuit and corresponding program in the system expansion by example.

This article from http://blog.csdn.net/hellogv/, reference must indicate the source! I recently want to develop on the MSP430, and I/O simulation on the first hand will be difficult. Fortunately, there are already many examples of the implementation of the soft serial port of the MSP430 on the Internet. Most of the Code in this article is referred> Logging .... It took a week to debug the I/O simulation UAR

Keil uvision, Keil MDK, Keil for ARM, realview MDK, Keil C51, Keil c166, Keil c166 From contact with MCS-51 microcontroller, we know that there is a software called Keil. When developing single-chip microcomputer, the C or assembly language is used. We know that neither of these languages can be directly filled into the single-chip microcomputer. If the execution is not executed for the time being, the size of the Code is not enough, it is enough to b

the USB framework My example code is for microchip technology's pic18f4550 microcontroller and mplab C6 compiler. I tested the code on Microchip's picdem FS-USB Development Board. A complete winusb project for the PIC along with companion Visual Basic and Visual C # applicationsAre available from my website. My PIC code uses Microchip's free USB framework, which is a set of source-code modules that handle low-level USB communications. Using the frame

What Cmsis is, although the name is similar to CMMI, but it doesn't really matter. To borrow the definition of Baidu Encyclopedia: ARM cortex™ Microcontroller Software Interface standards (CMSIS:CORTEX microcontroller software Interface standard) is cortex-m Vendor-independent hardware abstraction layer for the processor family. In short, cmsis is a software interface standard defined by arm and many compa

Simple and Convenient! The AVR Microcontroller has many advantages. I am also a loyal supporter, from 51 to AVR. I also learned PIC in the middle. I bought a learning board, LCD screen, and many other things when I was a beginner at 51. After my experience, when learning AVR, I started from the self-made download line. Note that this is just the beginning. Simple things have some limitations, but it is very useful for beginners, with it, you

consideration of the real-time monitoring of the single chip microcomputer running status, a chip is generated to monitor the running status of the single chip microcomputer,Commonly known as "Watchdog"(Watchdog) The application of the Watchdog Circuit enables the single-chip microcomputer to work continuously in the unmanned State. Its working principle is: the watchdog chip and the single-chip microcomputerAn I/O pin is connected, and the I/O pin is controlled by a program to regularly send h

Write Process When the MCU performs write operations, it first sends the 7-bit address code of the device and the Write direction "0" (a total of 8 bits, that is, one byte ), after sending the message, the SDA line is released and 9th clock signals are generated on the SCL line. After confirming that the selected memory device is its own address, a response signal is generated on the SDA line. After receiving the response, the MCU can transmit the data. When transmitting data, the

every embedded application has access to the lowest firmware and some hardware controls at some point. Drive design and implementation are key to ensuring that a system meets its real-time requirements. The following five tips are for each developer to consider when designing a driver. 1. Use design modeDesign Patterns are a solution for dealing with problems that can recur in software. developers can choose to waste valuable time and budget to reinvent a solution from scratch, or choose a solu

basic operation of the time spent, generally using microseconds to measure the speed of single-chip microcomputer, 51 single-Chip machine cycle includes 12 clock oscillation cycle, that is, if the 51 microcontroller using 12MHz crystal, then the implementation A machine cycle requires only 1μs, and if you are using a 6MHz crystal, it takes 2μs to perform a machine cycle. 2. Instruction cycle refers to the time required for a single-chip microcomputer
