reading values from the serial port

in Programming Questions • 1 year ago

Hi all

I'm communicating between SHT15 sensor and Arduino EtherTen via serial port.

I wanted Processing to read one set of values and evaulate it before it can read the next set of values.I am not sure if that is possible.

I have tried to do that in the code below. I get the following error. I am not sure if the way I have written my code actually is correct format.I have researched online but please advice

*****************************************************************************************************************************

expecting SEMI, found ')'

processing.app.SketchException: Syntax error, maybe a missing semicolon?

void draw() {

//background(inByte);

for (i=0; i<0) {

i = i+ 1 ;

while (myPort.available () > 0) {

int inByte = myPort.read();

char val = char(inByte);

//print(val);

String sc = str(val);

print (sc);

//String[] values = splitTokens(sc, ", ");

//print(values[0]); // Prints "a"

//print(values[1]); // Prints "b"

}

i=0;

}

Some advices:
- Please, check why there are several forum sections and they are for. That's not a question for Processing Implementations.
- When you have an error, it is best to indicate which line is pointed out. This code is small enough, but some can be long, and that's a good habit to take.
- I guess the error is pointed at the line with for: the syntax isn't right, you should verify it. Hint: the increment doesn't need to be inside the loop itself;
- If I read correctly, you can have an issue with the number of closing soft braces, too... Remember that when putting the caret after such brace }, the PDE highlight the matching one. Except if none is matching!
