这是官方文档里似例代码的注释,,SerialEvent()这个函数会在loop()函数执行完后被自动调用,不是通过中断的方式调用的。 可以理解为,数据来了,会放入缓冲区,然后loop循环完成一次,做一次处理? void serialEvent() { while (Serial.available()) { // get the new byte: char inChar = (char)Serial.read()...
This example shows how to enable callbacks to read streaming ASCII terminated data from an Arduino® board using the serialport interface. This example uses an Arduino Due; however, most Arduino boards should work. Upload a Program to the Arduino Plug in an Arduino board to your computer. ...
