设计的是一个数字频率计,通过八个七段数码管显示频率值。系统时钟选择的50M的时钟,闸门时间为1s(通过对系统时钟进行分频得到),在闸门为高电平期间,对输入的频率进行计数,当闸门变低的时候,记录当前的频率值,并将频率计数器清零,频率的显示每过2秒刷新一次。被测频率通过一个拨动开关来选择是使用系统中的数字时钟源模块的时钟信号还是从外部通过系统的输入输出模块的输入端输入一个数字信号进行频率测量。当拨动开关为高电平时,测量从外部输入的数字信号,否则测量系统数字时钟信号模块的数字信号。(附详细PDF文档介绍)-Design ist eine digitale Frequenz Meter, acht Sieben-Segment-LED-Anzeige durch die Frequenz. 50M Systemuhr ausgewä hlt Uhr, das Tor von 1s (indem man die Systemuhr), das Tor hoch ist in der Zeit, die Frequenz des Eingangssignals zu zä hlen, wenn das Tor niedrig wird, wenn der aktuelle Frequenzwert aufgezeichnet und die Frequenz-Zä hler gelö scht wird, aktualisieren Sie die Frequenz-Anzeige alle 2 Sekunden. Die gemessene Frequenz durch einen Kippschalter, um die Anzahl mit dem System Taktgeber Modul auswä hlen oder von einem externen Taktsignal durch das System Input-und Output-Module von einem digitalen Eingang des Eingangssignals Frequenzmessung. Wenn der Kippschalter hoch ist, von den externen Eingang des digitalen Signals oder digitale Messsystem Taktsignal Moduls digitale Signal gemessen. (PDF-Dokument mit detaillierter Beschreibung)
