SerialSocketEvent 未触发 [英] SerialSocketEvent not firing
问题描述
我已复制此代码:http://playground.arduino.cc/Interface/Java 到一个 java 项目,我试过这个:
I have copied this code:http://playground.arduino.cc/Interfacing/Java to a java project, and i tried this:
void setup(){
Serial.begin(9600);
while(!Serial);
}
void loop(){
Serial.println("Test");
}
在我的 arduino UNO 上,效果很好,但是当我在 esplora 上尝试时,该程序甚至没有触发 java 项目的事件侦听器.
on my arduino UNO, with great results, but when i tried it on my esplora, the program did not even fire the event listener for the java project.
推荐答案
Esplora 和 leonardo(均使用 ATmega32u4)要求您等到 cdc 序列准备就绪.Uno 有一个专用的 Atmega8/16u2 控制串行/USB 通信.
An Esplora and leonardo (both use ATmega32u4) require you to wait until the cdc serial is ready. The Uno has a dedicated Atmega8/16u2 controlling the Serial/USB comms.
在您的代码中,在您的 Serial.begin()
调用之后,添加一个循环以等待就绪:
In your code, after your Serial.begin()
call, add a loop to wait until ready:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect.
}
