AVR控制的SAB82525――HDLC通信 循环队列处理 完全是自己写的-AVR control SAB82525-- HDLC communication cycle Queue processing is totally wrote it myself

功能强大的51编程器，文件包里有PC机程序、编程程序和硬件电路。-powerful 51 programmer, a paper bag of PC and programming procedures and hardware circuit.

用8253-8255编写的定时响铃程序 可以定时两个时间点，很经典的程序-spent 8253-8255 prepared by the regular beep procedures regular two points in time, classic procedures

此程序为单片机开发过程中定时芯片ds1302的控制并用lcd显示的程序，用汇编语言编写。供参考用-procedure for microcontroller development process of regular chips ds1302 control and LCD display with the procedures in assembler language. For information

程序描述：这个范例说明如何使用8051，以及汇编语言的程序连结， 当我们按下向上数的按钮之后，程序就会把0到9的共 阳7段显示器字型码存入AT93C46；如果我们按下向下 数的按钮之后，程序就会把9到0的共阳7段显示器字 型码存入AT93C46。 程序每一次重新开始执行时(Power on 或是Reset)，8051 会先从AT93C46当中读出最前面的10个位组，然后 就反复地将这10个位组的数据经由PORT 1送到1个 共阳七段显示器。*/-Procedure Description: This example shows how to use the 8051, as well as links to assembly language programs, when we pressed up a few of the button, the program will bring a total of 0-9 yang seven segment display font yards into AT93C46 if we press Next down the number button, the program will bring a total of 9-0 Yang seven segment display font code into AT93C46. Process to begin again each time when the (Power on or Reset), 8051 will start with AT93C46 were read out in front, 10-bit groups, and then repeated these 10-bit groups of data via the PORT 1 sent to a A total of seven-segment display Yang.* /

芯片使用51+ch375,程序用180行C代码就能够读取FAT16文件系统U盘的根目录,可以看到根目录下的文件名,并可显示首文件内容-chips use 51 ch375, procedures using 180 OK C code can read FAT16 file system drives the root directory, we can see the root directory under the file name, would show the contents of the documents first
