基于NT69P20的遥控PS2键盘处理程序

对偏振图像进行融合处理。其中包括比较经典的小波变换，ihs垂直变换以及拉普拉斯金字塔变换。。。(The polarization image fusion processing. Including the more classic wavelet transform, ihs vertical transformation and Laplacian pyramid transformation. . .)

说明：  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.)

说明：  介绍汇编语言，属于教程一类的，想学习对硬件编程的朋友可以下载来看看。直接解压就可，CHM文件。(introduction to the compilation of language, belong to a category Guide, want to learn programming for the hardware can be downloaded friends to see. Decompression can be direct, CHM file.)

C8051F020控制语音芯片的汇编语言程序。已测试通过。(C8051F020 chip voice control assembly language program. Have been tested.)

利用外部中断输入引脚（以中断方式）控制步进电机的转动。要求：每产生1次中断，步进电机只能步进1步。(External interrupt input pin (interrupt) control the rotation of the stepper motor. Requirements: each generate an interrupt, stepper motor can only step Step 1.)

直接用手动产生单脉冲作为中断请求信号。 要求每按一次开关产生一次中断,在屏幕上 显示一次“TPCA Interrupt!”,中断10次后 程序退出(Directly by hand to produce a single pulse as an interrupt request signal. Each time you press the switch requires an interrupt is generated, show a TPCA Interrupt! On the screen, interrupted 10 times after the program exits)
