[英]Complete Serial String from Arduino to Processing
I am using Arduino and Processing. 我正在使用Arduino和Processing。 I am trying to send a string from the Arduino to Processing
我正在尝试从Arduino发送一个字符串到Processing
void serialDataOutput() {
dataString = "";
for (int i = 2; i <= 13; i++) {
if (digitalRead(i) == HIGH) {
dataString.concat(i);
dataString.concat(",1/");
} else {
dataString.concat(i);
dataString.concat(",0/");
}
}
//output "2,0/3,0/4,0/5,0/6,0/7,0/8,1/9,1/10,1/11,1/12,1/13,0";
Serial.write(dataString);
This is the code I have for generating the string, and an example output in the serial terminal. 这是我生成字符串的代码,以及串行终端中的示例输出。
However, in Processing, I am trying to get this string like this: 但是,在Processing中,我试图得到这样的字符串:
while (myPort.available() > 0) {
rawInput = myPort.readString();
println(rawInput);
myPort.clear();
}
This gives an output like this: 这给出了这样的输出:
2,0/3,0
/4,0/5,0/6,0/7,0
/8,1/9,1/10,1/11
,1/12,1/13,1
It is broken up over multiple lines. 它分为多行。 I need the input in processing exactly how it was sent from Arduino.
我需要输入处理从Arduino发送的确切方式。
How do I do this? 我该怎么做呢?
I think that your are reading the input buffer of Processing faster than your are sending the complete string from Arduino
. 我认为你正在读取Processing的输入缓冲区比从
Arduino
发送完整字符串更快。 Processing read the buffer because it has info ( myPort.available() > 0
) but arduino is sending info. 处理读取缓冲区因为它有info(
myPort.available() > 0
)但是arduino正在发送信息。 When the buffer is empty, Processing understand that it is the end of the string so it stops reading and print it. 当缓冲区为空时,Processing知道它是字符串的结尾,因此它会停止读取并打印它。 In next iteration of
loop()
, Arduino has sended info and Processing repeat until Arduino end. 在
loop()
下一次迭代中,Arduino已经发送了信息并且处理重复,直到Arduino结束。 Try reading the string char-by-char and concat it to a string until you read \\0
尝试读取字符串char-by-char并将其连接到字符串,直到您读取
\\0
