- 摘要 本电路以P89C58 单片机为中心、采用A44E 霍尔传感器测距,实现对出租车里程统计,并进行计价。采用看门狗电路MAX813L实现上电复位、手动复位和监视电压功能,时钟芯片DS1302在系统掉电的时保存单价、里程、车轮长度等信息和显示时间,人机界面采用液晶显示,为减小功耗可将液晶屏背光灯设为手动可调。并采用炜煌A6热敏打印机打印基本信息。本电路设计的计价器不但能实现计价功能,而且还能根据白天、黑夜自动调整计价模式,中途等待处理以及为避免一些作弊行为设计的防作弊功能。经检测本设计基本实

PN4
- 语言:VHDL 功能:该PN4序列的特点为将一个4位序列的前两位取异或,再让序列左移一位,用异或的结果作为序列的最后一位。序列周期是15,即15位伪随机序列。其中包括序列的产生模块和检测模块。对于误码检测,首先捕获相位。然后,规定测试的码的总个数,统计这些码中有多少个不能满足PN序列特点的,用计数器统计个数。如果发现误码过多,可能是相位失调,重新捕获相位,再进行误码检测。 仿真工具:modelsim 综合工具:quartus -Language: VHDL function:
