verilog等精度测量源码(附带SPI单工通信模块)
应用背景
使用verilog依靠等精度测量原理设计数字频率计,测量数据输出为64位,使用单片机进行简单的解码和显示,就能得到被测信号的频率,门控信号持续时间,也就是采样时间越长,fpga使用的晶振越准,越高速,测出来的效果越好,测量时间一定要高于被测信号的周期,这个只是取决于单片机对门控信号的控制。
等精度测量的最上层文件是dengjingduceliang.v
等精度测量的模块是DJDCL.v
spi通信模块是SPI_8BYTE
使用的方法是,三个文件放在一起,上层文件和fpga的io配置好,什么输入什么输出,然后把DJDCL.v的input和标准时钟,我的是50M,还有被测信号接在一起,会输出一个64位的数据,前32位为标准时钟计时,后32位为被测信号计时,传给mcu简单计算一下就有了被测信号的频率关键技术
1.1 测频方法
这种方法即已知时基信号(频率或周期确定)做门控信号,T为已知量,然后在门控信号有效的时间段内进行输入脉冲的计数,原理图如下图所示:
