（1）能显示里程，单位为公里，最后一位为小数位。

（2）能显示金额数，单位为元，最后一位为小数位。

（3）可设定单程价格和往返价格，单程价格为2元/公里，往返价格为1.5元/公里。

（4）车速<5公里/小时的时间累积为总等待时间，每5分钟等待时间相当于里程数增加1公里。

（5）起步公里数为3公里，价格为5元，若实际距离大于3公里，按规则3计算价格。

（6）按暂停键，计价器可暂停计价，按查询键，可显示总等待时间。

1 液晶尺寸是3.2寸，控制器是 ILI9341
2 SD卡4位模式DMA ，支持长文件名及中文文件名

制作出来的stm32出租车计价器实物图如下：

stm32单片机出租车计价器源程序如下:
