用汇编语言写的了一个定时计数器的程序，已经通过，实现良好...

此程序可以实现键盘发音功能，按1、2、3、4、5、6、7、8即可发音，按F6结束！-this procedure can be achieved pronunciation function keyboard, can be pronounced by 1,2,3,4,5,6,7,8, by the end of F6!

包含7920液晶显示芯片驱动，用户可参考设计使用-Contains 7920 chip LCD driver, the user can use the reference design

本程序是用汇编语言来写的一段关于lcd的使用，还有并行通讯口的内容-This procedure is used assembly language to write a paragraph on the lcd use, as well as the contents of parallel communication port

1) 东西方向车辆放行20秒钟。即东西方向的绿灯和南北方向的红灯同时点亮20秒钟； 2) 20秒钟后，东西方向的黄灯闪烁2秒钟，以警示车辆将切换红绿灯。此时南北方向仍维持红灯点亮。在南北方向亮红灯期间，在2位数码管上显示计数值（每秒减1），从20减至01。 3) 东西方向的黄灯闪烁2秒钟后，转为南北方向放行20秒钟。即东西方向的红灯和南北方向的绿灯同时点亮20秒钟； 4) 南北方向放行20秒钟后，转为南北方向的黄灯闪烁2秒钟，以警示将切换红绿灯。此时东西方向仍维持红灯点亮。 5) 南北方向的黄灯闪烁2秒钟后，再转为东西方向车辆放行20秒钟。如此循环重复。 -1) direction vehicle release 20 seconds. What is the direction of red and green light at 20 seconds, 2) 20 seconds later, the yellow lights flashing warning vehicles with 2 seconds, switch to the traffic lights. This is still remain red light north-south direction. In the south during the red light, in the direction of the digital display tube of 2 per plan (minus 1), from 20 to 2001. 3) the yellow lights flashing direction to 2 seconds later, the south direction release 20 seconds. What is the direction of the north-south direction of red and green and light 20 seconds, 4) north-south direction after 20 seconds to release the north-south direction, yellow lights flashing warning, with 2 secon

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.
