PIC16c57 Bright embedded control module模拟串口通信部分-PIC16c57 Bright embedded control module

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.

可编程并行接口实验源程序，通过此实验可掌握8255方式0的工作原理及使用方法。编程从8255C口输入数据，再从A口输出-procedure for a programmable parallel interface experiment source, the passage of this experiment can seize 8,255 0 means the working principle and methods of use. Programming from the 8255C I input data, from A mouth output.
