51单片机驱动HX711，实现称重、单价选择、计价，显示使用的是LCD1602。已通过软件标定校准和砝码校准。附上视频链接：链接：https://pan.baidu.com/s/1laQH_O64TADYU5DC_vQFNQ

单片机源程序如下:

- u8 Price_Val[4];
- float Total_Price;
- void Weight_Datapro(unsigned int value)
- {
- Weight_Val[0] = value / 10000;
- Weight_Val[1] = value % 10000 / 1000;
- Weight_Val[2] = value % 1000 / 100;
