多任务操作系统ucOSII移植到Keil上的源码-Multi-tasking operating system ucOSII transplanted to the source Keil

一个4510的BIOS,已经测试通过了,在里面添加了基于USB的烧写方法-a BIOS 4510, has passed the test, they add a USB-based method of burning

红外线遥控器按键检测程序. 通过检测两次下降沿之间的时间差判断接受到的数据位. 已经通过了测试,能够正确区分出32bit数据的遥控器按键键值. 具有数据重发功能,但是数据的重发有点频繁. 使用晶震频率为11.0592MHz,所有定时值都是基于这个频率计算. 占用很少量的CPU时间,使用了外部中断0接受数据,定时器0进行计数, 定时器1作为串口的波特率发生器(Band = 9600).-Infra-red remote control button detection program. By detecting falling edge twice to determine the time difference between the received data bit. Has passed the test, could correctly distinguish 32bit data button remote control key. With data re-issued, but data a bit of re-issued frequent. Zhenyuan frequency of use of crystal 11.0592MHz, all timing values are calculated based on this frequency. occupied by small quantities of CPU time, use the external interrupt 0 to accept data, timer 0 to count, timer 1 as a string port baud rate generator (Band = 9600).

单片机控制MAX485的485总线收发程序，已经用于实际工程中！超级稳定！-MAX485 single-chip control of the 485 bus to send and receive procedures are used for the actual project! Super stable!

拷拷贝到你的Keil安装目录下的c51in文件夹中。 工程文件中需设置一下: project->Option for Target Target1 选Debug页 左侧最下面 Dialog Dll 一般是DP51.DLL，不用修改 Parameter 中是 -P51 在其后加入 -dledkey 即该行看起来应该是这样的： -p51 -dledkey 保存即可 进入调试后，点击：Peripherals，其中多出一个“键盘LED实验仿真板”选择该项即可。-emboss your copy of the Keil installation directory under the decoder bin folder. The project document to be provided as follows : project-gt; Option for Target Target1 election Debug bottom of the left page is generally Dialog Dll DP51.DLL, need not be amended Parameter is- P51 add after-dledkey that the bank should look like this :-p51-can be preserved into dledkey to debug and click : Peripherals, in which more than a "keyboard LED simulation board," which can be chosen.

多功能广告牌，12864液晶显示，首行滚动显示广告语，按键选择广告，预存5条广告，18B20检测温度显示，DS1302万年历显示，可调时间，具有掉电保护，串口向PC机实时传送温度、时间信息-Multi billboards, 12864 liquid crystal display, the first-line scrolling display advertising language, button select advertising, stored five advertisement, 18B20 test temperature display, DS1302 calendar display, adjustable time, with a brown-out protection, serial port to the PC, real-time delivery temperature, time information

1602的程序，写的很规则，希望对大家有帮助，是电脑里存了很久的，曾经自己写的-1602 procedures, the rules are written, in the hope that we help keep the computer for a long time, and have written their own

这是一个简单的红外解码程序，是针对9ms起始码和4.5ms结束码的红外信号。晶振用的是11.0592M的，经测试能用。-This is a simple infrared decoding procedure is 9ms start code and end code 4.5ms infrared signal. 11.0592M crystal is used, and can be tested.

51系列单片机读卡程序，本人亲测，适合考勤、门禁。-51 Series single-chip reader program, I pro-test for time and attendance, access control.
