more sequences of repeated use instructions. of course, the optimization level is not as high as possible, and should be appropriately selected according to the specific requirements. in-depth analysis of Keil C51 bus peripheral operation ProblemRead the "SCM and Embedded System Application" in the 10th issue of 2005 Magazine, "Experience Exchange" column of an article "Keil C51 on the same port of the con

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

Keil Optimization Level settingOptimization level description (for reference only):The Code optimization bar is used to set the C51 level of optimization. There are 9 levels of optimization (as written in the book), and the high level of optimization includes all the previous levels of optimization. The various levels are described below:0-Level optimization:1, constant folding: Whenever possible, the compiler executes a calculation that evaluates to

using the car later, you can only weld the "Bracket" at the bottom and then install it on the cave board like this: Operating System Selection The initial consideration is uC/OS-II. It is very famous (often seen) and has strong functions (sounds like it), and the operating system is also introduced in the books I bought. The US/OS-II Job Scheduling is a fully preemptible Job Scheduling Method Based on the job priority, the low-priority job being executed can be interrupted by a high-pr

Original address: http://blog.csdn.net/yannanxiu/article/details/52438351 Overview We will need to print debugging information when we are developing C/d, we are accustomed to use printf function when we print debugging information, but in Keil C51 environment, because our program is downloaded to SCM, we can not directly print to the serial port when using printf function. This time, we need to redirect the output of the printf function. redirect

Keil Download the program sometimes "The connected Emulor is a J-link clone" problem, which means that the identification of the jlink of piracy, should be a new version of the Jlink appear. My method solves this problem by replacing the file. Replace the folder directly. Replace the folder is E:\Program files\keil\arm path under the Segger file, replace the file link under, directly delete the original S

language programming.The raw data collected by the forward channel in the real-time control system are mostly fixed-point integers, such as the conversion result of A/D converter of the forward analog channel, the counting result of timer/counter, etc., are fixed-point integers. And the system of the back channel can accept the input amount is an integer, that is, the finite word error caused by quantization is unavoidable, the precision of the control of the decimal place is not accepted by th

Ⅰ, overviewThe previous article is a summary about the use of Keil-common functions (ii), the article then summarizes the previous article.I will summarize each article of Keil use method together, review the previous summary please click the following link (click to read the original), Keil use Method (summary):http://blog.csdn.net/ybhuangfugui/article/details/5

Newest Single Chip Microcomputer virtual simulation platform build proteus7.9 + Keil uvision4 + mdk414 Proteus has excellent single-chip computer simulation function and supports multiple single-chip computer virtual simulation. A powerful virtual simulation platform can be built using Proteus and other programming software. Simulation chip, such as AT89C51, intel8086, arm7lpc2000, and arm cortex m3 lm3s Latest Virtual Simulation Platform C

Install keil uvision4to register keil_lic.exe and install keiluvision4 1. First of all, download the EXE executable file of keil uVision4 on the Internet. There may be two versions: 51-core single-chip microcomputer (33.3 M) and microcontroller Development (244 M ), you can choose based on your actual needs. 2. Follow the steps to install keil uVision4 Note: The

1) Purpose After Keil and Proteus are installed, only the two software can be correctly installed to complete online debugging of the two software.2) Principle The Keil software is an integrated development environment in which the source code of the single-chip microcomputer program can be compiled and debugged. The Proteus software is a circuit simulation software, in which the circuit diagram can be desi

Ⅰ , overviewLearning a software development, the development of tools can be said to be particularly important. Because the Keil integrated development tool supports the development of a variety of MCU platforms, it is more common on the market and is also a powerful IDE. So, for most people, choosing Keil is the perfect choice for a single-chip or embedded developer.The next few days starting today summari
