The function print(char) does not exist?

in Programming Questions • 6 months ago

Hello

I'm having some problems with my serial communication between my Processing and my Arduino. I believe my main problem is within my Processing. I feel like I put everything accordingly but it gives a such problem.

This is my code

Copy code

//println (get(mouseX, mouseY) ); // Print line the location of the mouse on-screen.
if (get(mouseX, mouseY) == color (255, 0, 0) ) { // If it is within a color range of red.
//println("red"); // Print line red.
key = 'a';
cntrPair1.value++; // Then decrement number on-screen by one.
delay(150);
// Delay of 200 milliseconds between allowable clicks.
Serial.print('a');
}

I seem to have put in everything which was needed to start the communication but the problem is from the serial.print. That would be grateful if you can help.

Thanks

Serial.print('a');
expects a static function in the Serial class, ie. a function using no fields from the class, a bit like random() or sin().
You want a
serial.print('a');
where serial would be the variable holding the instance of the Serial class.
