首先,分别对8255、8253进行初始化,设置8255为A口、C口输出,设置8253的计数器0为工作模式3;其次,设置IRQ7的中断矢量,使得有IRQ7中断时调用SERVER;再次,调用INIT对计数值初始化;最后,主程序循环等待中断,开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine

本程序由国外的Vulture大哥编写,并公布了源码,这个是他95年的一个作品,可以说是在当时是非常成功的!
这个程序是巧妙的利用了坐标的不断变化,从而实现了由星星构成的箱子3D转动!
为了尊重版权,本人未对源码注释进行翻译,这样做也可以让国内的汇编爱好者自己琢磨国外的汇编编程的思维-This program prepared by the foreign Vulture brother, and announced the source code, this is his 95 years, a work can be said that at that time was very successful! The program is clever use of changing coordinates in order to achieve a box formed by the stars, 3D rotation! In order to respect copyright, I did not comment on the source code translation, this would also enable the compilation of country fans on her own way of thinking outside of the compilation of programming

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.
