MAX111数字万用表单片机源程序 12864显示

ID:217168 · 发表于 2017-7-4 18:09

用12864液晶屏来显示的单片机数字万用表制作资料,菜单显示处理很经典：

单片机源程序如下:

/************************************************************************************************
控制说明：
电阻测量： 10: send0(0x80); 100: send0(0x81);
1K: send0(0x82); 10K: send0(0x83);
100K: send0(0x84); 1M: send0(0x85);
10M: send0(0x86);
直流电压测量：100MV: send1(0x04);
10V: send1(0x08);
100V: send1(0x10);
10KV: send1(0x20);
交流电压测量：100MV: send1(0x06);
10V: send1(0x0a);
100V: send1(0x12);
10KV: send1(0x22);
直流电流测量： 1MA: send2(0x02);
10MA: send2(0x04);
100MA: send2(0x08);
10A: send2(0x10);
交流电流测量： 1MA: send2(0x03);
10MA: send2(0x05);
100MA: send2(0x09);
10A: send2(0x11);
注:初始化时要全部处于非工作状态<send0(0x08) send1(0x00) send2(0x00)>使用时选择相应指令,返回时关断.
