Arduino Due有12路模拟输入端, 每一路都有12位精度(0-4095)。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...

Arduino DueOverviewWhen I first got my Due in the mail I searched the web for a simple overview to help me better understand what new features Arduino is bringing to the table with the new development board. After finding next to nothing I decided to wri
It is possible to change the resolution of the ADC with analogReadResolution(). The Due’s analog inputs pins measure from ground to a maximum value of 3.3V. Applying more then 3.3V on the Due’s pins will damage the SAM3X chip. The analogReference() function is ignored on the Due. ...
ADC bits Note:The arduino functionanalogReadResoution() allows theanalogRead() function to return a different number of bits (The number of bits depends on your Arduino chip). Some of the Arduinos e.g. DUE have 12 bit ADCs built in, so returning 10bits will keep the code in these board...
The Due has 12 analog inputs, each of which can provide 12 bits of resolution (i.e. 4096 different values). By default, the resolution of the readings is set at 10 bits, for compatibility with other Arduino boards. It is possible to change the resolution of the ADC with analogReadResol...
分辨率和精度—即Resolution和Accuracy。这是两个不同的参数,却经常被混用。并且ADC制造商在数据手册中定义ADC性能的方式也令人困惑,可能会让大家在应用开发中导致错误的推断。但事实上,分辨率并不能代表精度,反之亦然。 2022-05-12 15:19:58 ADC的各种指标如何理解,如何提高ADC转换精度 ...
this works at 12 bit eventually use to10BitResolution use this or the original analogRead not both. This is slightly faster than the original, the code is very similar, yes copied code from the original but with some optimizations. If this is the only DueAdcFast function you use, use zero...
