/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...
in the setup and duplicate the doEncoder function into say, doEncoderA and doEncoderB. You also need to move the other encoder wire over to pin 3 (interrupt 1). */ BY:dskv注意!!! 在中断程序中使用Serial.Print要特别注意,大多数情况下它会失败, 可是有时它会成功, 这是个程序比較糟糕的bugs...

由于Arduino项目是完全开源的,所以pinMode(pin, mode)函数原型可直接在Arduino开发环境目录下的hardware\arduino\cores\arduino文件夹里的wiring_digital.c文件中查看。函数原型有助于我们深入了解Ardnino的基本函数的底层实现方式,但这部分的内容需要在单独深入学习AVR单片机的基础上进行,本书将这些函数原型从文件中提取...
