编写一个自定义INT 79H的中断服务程序

利用AT89C51 ,可以读取基于IC7135的电压表头的信号. -Use AT89C51, can be read based on the voltage meter IC7135 first signal.

实现企业财务部门对工资进行集中管理。可供财务人员对企业的员工进行添加、删除，对员工的基本工资、浮动工资、工资发放进行管理以及提供财务人员查询员工的基本工资、浮动工资和总体工资并且可以打印报表；-Corporate finance department for centralized management on wages. Financial officer for the staff of enterprises to add, delete, on the staff of their basic wages, floating wages, payroll and financial management staff personnel inquiries basic wages, floating wages and overall wage and can print statements

AVRStudio4使用说明,操作简单，使用方便,很容易就学会-AVRStudio4 instructions, simple operation, easy to use, it is easy to learn

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.

正弦波驱动电机伺服控制汇编语言源程序！可应用于永磁同步电机-sinusoidal driven servo motor control assembly language source code! Can be applied to PMSM

对图像做了简单处理，最后一段代码段实现4各功能，汇编运算较多-Do a simple image processing, the realization of the last paragraph of the code segment 4 of the function, the compilation of more computing

我实验板带的实验程序，留给初学者看看吧，其他的我再整理一下，陆续上传吧-I experiment with the experimental procedure sheet, leaving beginners take a look at it, other like me to organize a series of upload it

6路红外遥控电路，用3010遥控器1-8键加电源按键。-6-channel infrared remote control circuit

DS1302的驱动程序，C51编的，最后由proteus仿真的，可以显示设定时间，程序中的延时函数是由汇编语言实现，也就是说这程序是C和汇编混编的。-DS1302 driver, C51 series, and finally by the Proteus simulation can show the set time delay proceedings by the assembly language function is to achieve, that is to say that the procedure is of mixed C and assembler.
