1.analogRead ( pin ) : ① 模拟输入引脚是带有ADC(Analog-to-Digital Converter,模数转换器)功能的引脚。 ②它可以将外部输入的模拟信号转换为芯片运算时可以识别的数字信号,从而实现读入模拟值的功能。 ③模拟输入功能需要使用analogRead() 函数。 参数:参数pin是指定要读取模拟值的引脚,被指定的引脚必须是模拟输入...
默认情况下, 模拟输入精度为10位, 和其他型号的 Arduino 控制器一样。通过analogReadResolution()你可以改变ADC的采样精度. Due的 analog inputs引脚测量范围为 0 至 3.3V。如果测量高于3.3V电压,可能会烧坏 SAM3X。analogReference() 函数在Due上是无效的. AREF 引脚通过一个电阻桥接到 SAM3X 模拟参考脚. 如果要...

values). Resolution: ADC can distinguish the minimum analog 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 ...
Each of the 6 analog inputs, labeled A0 through A5, provides 12 bits of resolution (i.e., 4096 different values). By default they measure from ground to 5 volts.I2C bus, TWI: SDA and SCL pins that are near to the AREF pin.TWI: A4 or SDA pin and A5 or SCL pin. Support TWI ...
