cputicker
- CPU 的精确计时器 This class implements an MFC wrapper class for the Pentium-specific (or better) time stamp counter which can be accessed using the "RDTSC" assembly language instruction. This counter has a resolution in terms of PCLKS (processor clocks)
ddssdfd
- 以把直接数字频率合成（DDS）看成这样一种技术，它能用数字值形式的信号控制正弦波的频率。最简单的DDS电路包括一个二进制计数器，一个以等间隔正弦波值进行全波编程的ROM，以及一个数模转换器，用于将存储的正弦波值转换为但这种结构并不灵活。 -To the Direct Digital Synthesis (DDS) as such a technology, it can use the digital value of the form of the frequency of sine wa
VC(MP411)
- MP411是一款USB2.0/1.1总线兼容12位采集模块，具有16路模拟输入,工作在软件启动模式、二路12位DA输出(MP411)、开关量16路输入/16路输出、一路20位计数器（MP411），支持频率测量。采用USB总线，支持即插即用。MP411的所有功能设置都可以通过操作台控制，提供源代码。-MP411 is a USB2.0/1.1 bus-compatible 12-bit acquisition module with 16 analog inputs, work in softwa
counter
- 这是一个用单片机做的频率计，外设需要配置一个同步门，之前可以实现精确的计频-This is a frequency counter to do with the microcontroller, peripherals need to configure a synchronization gate, before the meter can achieve accurate frequency
xzvxvxcvz12g
- In the measurement of frequency is actually 1s to count time signal, numerical is signal frequency. Using single-chip microcomputer frequency plan by using two kinds of method, usually the first approach is to use own counter chip counting input puls
