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, ...

data as electrical pulses that represent sequentialbits. The zeros and ones that carry the information that makes up a byte can be represented in various ways. The scheme used by Arduino is 0 volts to represent a bit value of 0, and 5 volts (or 3.3 volts) to represent a bit value of...

The first value is the data type (0=byte, 1=16 bit int,2=32 bit int,3 = float). The second parameter is the position in EEPROM, the value is stored. The third parameter is the current value. The rest of the line is a short description of the parameter....
#define sbi(sfr, bit) (_SFR_BYTE(sfr) |= _BV(bit)) #endif Using them is very simple, if we want to set to 1 the Enable Bit of the ADC we can just write: sbi(ADCSRA,ADEN); While if we want to set it to 0 (id estclear it) we can just write: ...
