AT89C52单片机为核心,完成出租车计价器的设计。采用AT24C02实现在系统掉电时保护,计费显示

采用8位8段数码管显示,该设计不仅可以计费,还可以实现白天黑夜的调价, 以及中途等待一段时间后总金额的增

加,另外设置清零里程按钮用于清零里程和总金额。利用proteus仿真软件模拟出租车计价的功能。-WithAT89C52asthecore, thearticlecompletesthedesignof taximeter, whichrealizesthepro-tectionof electricity cutting throughAT24C02. Thebilling isdisplayedthrough8- bit 8- sectiondigital
