This system uses the control style of serial communication. The connection control between the ARM embedded system and the CPLD replaces of the control between computer and CPLD, because the utilization of ARM intellectualizes the system and simplifies the program. The utilization of CTLD increases the pin numbers connected with the peripheral device.

系統(tǒng)采用串行通信方式911视频黄色，用ARM嵌入式系統(tǒng)與CPLD相連接取代傳統(tǒng)上采用的計(jì)算機(jī)連接CPLD方式的控制www.youjizz.com.日本，由于ARM的運(yùn)用使系統(tǒng)控制陣列天線更具智能化、應(yīng)用程序更簡(jiǎn)化黄色片三级片久久，CPLD的使用大大增加了與外設(shè)相連接的引腳數(shù)国产一级91无码乱码电影，滿足了項(xiàng)目中對(duì)多條控制線的需求。

In view of these shortcomings, this frequency meter has made the radical innovation in the design, its merit is: Uses the core component is the advanced monolithic special-purpose frequency measurement component -- monolithic frequency meter, the integration rate is high, the volume is small, consumes the electricity province, function, has realized the frequency meter high integration and the microminiaturization; So long as the monolithic frequency meter adds on the crystal oscillator, the measuring range choice, the frequency demonstrated and so on the very few components then constitute DC to the 10MHz miniature basic frequency measurement electric circuit; But the biggest merit was this frequency meter has realized monolithic frequency meter, frequency sampling electric circuit and the monolithic microcomputer three between hardware and the software connection completely, caused the frequency measurement measuring range the choice, the frequency data survey, the sampling as well as the code frontier transformation and the data dump possible monolithic microcomputer software programming automatically to carry on, thus has realized the frequency measurement and the sampling work intellectualizes completely, causes this system already to be possible to constitute a miniature intelligence to measure rate the instrument core electric circuit independently, also might take in the large-scale automatic control or a test system intelligent subsystem.
