通讯规则:
1:时钟7.3728 MHz/波特率9600/9个数据位/奇校验/1个停止位/硬件多机通讯功能/
2:通讯连接采用硬件MAX485,双向单工
3:每个上行/下行的数据包的字节个数都是一样的(通讯数据量)
4:每个上行/下行的数据包都采用CRC8校验
5:数据接收采用中断+查询的方式
6:总是由主机向从机发送一个数据包,从机收到数据包后向主机回复一个数据包
7:不管是主机还是从机,如果收到的数据包有任何错误,都将丢弃该数据包,等效于没有接收
8:从机之间不能相互通讯,必须通过主机才能交换数据
9:无效地址是0,主机地址是1,从机地址是2.3.4......广播地址是255 -err

停车场显示是日常生活中使用很平常的系统,停车场显示系统的核心是LED显示。本次设计使用KH-310实验箱,使用点阵模块和数码管模块,根据显示的扫描原理,利用8X8点阵模拟实际停车位并由数码管显示车位信息。- Parking is a show system that everyday life is usual to use the information.parking display system is the core of the LED display. The design of the experimental use of KH-310 boxes, the use of dot-matrix modules and digital control module, according to the scan shows that the principle of the use of dot-matrix 8X8 analog actual parking spaces by the digital display of information.
