Hi, new to processing and this might seem obvious but how do i update text? the examples i've seen don't seem to work and involve a kludge of drawing over the text with a rectangle (surely this isn't the answer....)
the application is simple - it writes to a serial port and gets an answer back from an arduino with ambient temp and the time. the text scrolls down the screen with the current code.
import processing.serial.*;
Serial myPort;
String val;
void setup()
{
size(500, 500);
myPort = new Serial(this, "COM5", 9600);
}
void draw()
{
frameRate(1);
textSize(32);
myPort.write("temp?");
while ( myPort.available() > 0) {
val += char(myPort.read());
}
println(val);
if (val != null && val.length() > 9) {
text(val.substring(9),50,100);
}
}
