6、更改I2C地址 要在调用compass.setADDR(BYTE_VALUE);之前更改I2C地址呼叫,compass.init();如下所示: 1 2 3 4 voidsetup(){ compass.setADDR(BYTE); compass.init(); } 7、更改模式,数据速率,比例,采样率 您还可以更改QMC5583L芯片的模式,灵敏度,采样率和输出率。等等,只需在调用compass.setMode(MODE, ...

signal change. Arduino Uno's ADC resolution is 10 bits, which means that it can distinguish the value between 0 and 1023. Reference voltage: The reference voltage of Arduino UNO is usually 5V, which means that the maximum input voltage of ADC is 5V, corresponding to the maximum value of ...
