一段纯 3D 的 DOS 动画，据说是获一等奖的作品。虽然它不是最精美的但是当你得知它只有 4K 时，会不会立刻疯死掉呢-Section of the DOS of pure 3D animation, won the first prize is said to work. Although it is not the most beautiful, but when you know it is only 4K, it will not immediately die, it was crazy

电子密码锁程序,用ASM编写,键盘6位密码,有开锁报警子程序-Electronic code lock procedure, prepared by ASM, keyboard 6 password, have become disengaged alarm subroutine

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.
