ADC0-ADC5 其实是作为 PC0-PC5 的第二功能存在的,分别对应 Arduino 定义 A0-A5。也正因为次,在 Arduino 的官方指南中提到,“The analog input pins can be used as digital pins, referred to as A0, A1, etc. ”。说的是,模拟输入口可以当数字口一样用。对于A0-A5来说,确实不错。但对于第一功能就...
/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...

Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5...

When I'm using configurePin and readVoltage for analog pins using an Arduino Leonardo board I'm getting the following errors in R2023B: "specified Key type does not exist" and "the first input must contain a multiple of 2 elements.." See code snippe...
I am running an Intel edison arduino board with Yocto, edison updated to libmraa 0.6.0. When I try to set up for analog in, I get the error message
