SPI串口的内核实现spicore SPI串口的内核实现spicore-SPI string mouth essence realizes spicore the SPI string mouth essence to realize spicore the SPI string mouth essence to realize spicore

在quartus下搭建的数字锁相环，能实现频率自动跟踪。(The digital phase-locked loop built under quartus can realize automatic frequency tracking.)

说明：  QPSK 调制 与 解调的源代码 可综合 出波形(QPSK modulation and demodulation of the source code)

说明：  资料是本人根据相关文献资料用vhdl语言编写的旋转机械鉴相信号倍频的程序，multifre1.vhd是倍频程序，multifre1.vwf是仿真波形文件，stp1.stp是虚拟逻辑分析仪signaltap文件。该倍频程序可以直接使用，可以设置倍频数，修改实体参数N即可。(According to the literature data is the information I have written in with vhdl Rotating Machinery Kam believe that the procedure multiplier number, multifre1.vhd is the multiplier process, multifre1.vwf is the simulation waveform files, stp1.stp a virtual logic analyzer signaltap file. The multiplier process can be used directly, you can set the multiplier number, modify the parameter N can be solid.)
