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
2、数字输入上拉 DigitalInputPullup - 输出上拉串口 InputPullupSerial This example demonstrates the use of INPUT_PULLUP with pinMode(). It monitors the state of a switch by establishingserial communicationbetween your Arduino and your computer over USB. 本例演示如何使用 pinMode 和 INPUT_PULLUP。
//Declare A5Analogpin as input pin pinMode(A5, INPUT); //Declare4-13 Digital Pins as Output Pins (For controlling 10 x ROHM LEDs) pinMode(4, OUTPUT); pinMode(5, OUTPUT); pinMode(6, OUTPUT); pinMode(7, OUTPUT); pinMode(8, OUTPUT); pinMode(9, OUTPUT); pinMode(10, OUTPUT); ...
