CRC校验采用多项式编码方法。多项式乘除法运算过程与普通代数多项式的乘除法相同。多项式的加减法运算以2为模，加减时不进，错位，如同逻辑异或运算。-CRC polynomial used coding method. Polynomial multiply and divide computing process and the general polynomial algebra multiply and divide the same. Polynomial and subtract operations for the two to die, not into the Modified, dislocation, as logical XOR.

应用背景AM2321是广州奥松电子生产的数字式温湿度传感器。虽是国产品牌，其精度也可以与国外的主流温湿度传感IC媲美。美中不足：与国外同精度产品相比，AM2321的重复性和漂移指标偏大；只能手动焊接，量产时会很不方便。关键技术 AM2321支持5V工作，将电源、地、SCL、SDA四个管脚直接与开发板子的对应管脚相连。对于Arduino UNO，I2C总线的SDA信号线对应A4管脚，SCL时钟线对应A5管脚。之后，SCL、SDA线需要通过上拉电阻连接到5V电源，电阻值可取4.7k或10k。 IIC总线　LCD１６０２显示，ｕａｒｔ串口上传
