用VB做的一个简单通讯录

用DSP5410实现PN码,汇编语言编程-with DSP5410 achieve PN code, assembly language programming

学习汇编语言编制的程序，非常参考价值，我认为汇编比较难。-Learning assembly language produced by the procedure, very useful, I think more difficult to compile.

该程序是判断某年是否是闰年，即输入任何一年份，若是闰年，则输出闰年，若不是，则输出不是闰年。

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.

判断闰年，怎么说，有兴趣可以看看吧，算法应该大家都会～-judgment leap year, how that interest can look at it, the algorithm should we all ~

用汇编语言编写的数字时钟程序，可以进行时间设置和闹铃设置等功能。-assembler language of the digital clock procedures that can be set-up time and set the alarm function.

用汇编编写的密码锁，proteus仿真，程序，原理图全套，希望对需要的人有用-Compilation prepared by using locks, proteus simulation, procedures, a full set of schematic diagram, in the hope that those who need it useful

这是12864 带字库的显示子程序 reset 是初始屏幕的 display 是显示数据的 input是输入地址的指令-This is the 12864 with reset font display subroutine is the initial screen display is to show the data input is the input address command

这是一个汇编程序，是个简单的闹钟程序，可以获取系统时间、可以校时！-This is an assembler, is a simple alarm clock program, you can get the system time, to school, when!
