Realizes the T0 precise fixed time using Keil C51_Keil, timing
Monday, December 7th, 2009 at 13:13 | No commentsCategories: Embedded systemShort Content: Designs a simple calendar clock system using 89C51, the clock system hardware mainly the timing circuit which, the replacement controls by the monolithic integrated circuit and so on auxiliary circuit, the pressed key electric circuit, the nixietube display circuit, the electrical power system and so on composes. The calendar clock may demonstrate year, month, divides, the second; May establish the year, the month, divides the timing control electric circuit controls by at89C51 monolithic integrated circuit; Presses a key ... -
Connects many same address I2C equipment
Wednesday, December 2nd, 2009 at 06:49 | No commentsCategories: Embedded systemShort Content: Myself begin studies C, once damaged severely for this question brain ^_^, is a monolithic integrated circuit system has two above same address I2C equipment, is unable with two identical to the SDA/SCL pin, #include “stc89c51.h”#include “iic.h” sbit scl0=P3^5;sbit sda0 = P3^4;sbit scl1= P3^3;sbit sda1 = P3^2;// here has only written two I2C equipment, if needs to be possible to add on sbit scl2=xx again; sbit sda2=xx; In fact many equipment's scl feet may use in common unsigned char ... -
The monolithic integrated circuit design and the KeilC programming summarize_Keil, SCM
Monday, November 30th, 2009 at 22:46 | No commentsCategories: Embedded systemShort Content: 1 basic principle The quality is a key. Nobody will feel to the very bad work satisfies. When completes the high grade work, you will feel for this reason proud. No matter you whether to know, you can obtain the prestige because of yours high grade work. Therefore, if wants the matter which does for oneself to feel proud, needs to establish individual standard, and to achieve this standard to try hard to struggle. Is achieving these standard time, ... -
The Hash search law realizes in Keil C51_C51, Keil, Hash
Saturday, November 28th, 2009 at 22:10 | No commentsCategories: Embedded systemShort Content: Abstract: Hash (hash) is one important storage method, is also one common search method. It is refers to between the record storage location and its key words establishes definite corresponding relationships. This article take the radio frequency cards entrance guard controller as an example, explained that with the radio frequency heating power number achievement key words, searches the law with Hash to determine whether this card does open the door, and gives corresponding Keil the C51 procedure. In ... -

Keil C51 to identical port
Saturday, November 28th, 2009 at 07:41 | No commentsCategories: Embedded systemShort Content: The C language is current universally acknowledged highly effective succinct and draws close to one of hardware's programming languages. Begins in 2O the C language to the monolithic integrated circuit MCS-51 on transplant the century 8O age the mid and late part, passed through near 1O year the development, the C language overcomes has had the code to be excessively long, the running rate slow shortcoming, because and the C language in aspects and so on development speed, ... -
Keil C51 main line peripheral device operation question thorough analysis_C51, Keil, port
Saturday, November 28th, 2009 at 06:40 | No commentsCategories: Embedded systemShort Content: Read "Monolithic integrated circuit And Embedded system Application" in 2005 the 10th issue of magazine "Experience Exchange" a column article "Keil C51 after Identical Port's Continual Read Method" (original text), the author thought that this article has not carried on two solutions which on this question in the thorough accurate analysis article mentioned not to be direct and to be simple. The author thought that this is by no means in Keil C51 cannot process to a port ... -
Under Keil C51 fast decimal arithmetic algorithm_C51, Keil, fractional arithmetic,
Saturday, November 28th, 2009 at 04:48 | No commentsCategories: Embedded systemShort Content: 0 introductions In the real-time control system programming, often involves to the decimal arithmetic question. In the computer system with the binary system expressed that the decimal method has decides the points method of portrayal and the floating number method of portrayal. Uses the floating number method of portrayal expression the decimal scope to be big, the precision is high, but a procedure generation of code length, the operating speed is slow. The fixed-point mathematical table shows the decimal ... -
