Arduino Mega是一块以ATmega2560为核心的微控制器开发板,本身具有54组数字I/O input/output端(其中14组可做PWM输出),16组模拟比输入端,4组UART(hardware serial ports),使用16 MHz crystal oscillator。由于具有bootloade
串口事件响应,非必要——serialEvent() 什么是串口 到目前为止,介绍的Arduino API接口都是一些比较底层的接口——即简单的通过电位高低获得指定输入输出的信号。既然这部分系列的文章是介绍Arduino的默认系统API,那么作为嵌入式设备需要提供的几个重要接口之一的——串口协议自然不能不提到。
