hello,
im asking this more out of curiosity than anything else since i solved my problem, but i would still like to know how this works.

when i send an integer above 255 it gets split to two bytes before it gets sent, and i would like to know how that works so i can reassemble it in arduino.

right now i split it myself with the following code:

void send(int byte16)
{
 int half1=byte16>>8&255;
 int half2=byte16&255;
 myPort.write(half1);
 myPort.write(half2);
}

then put it back together like:

if (Serial.available() > 1) {
   int byte1 = Serial.read();
   int byte2 = Serial.read();
   int byte16=byte1<<8|byte2;
}

which works just fine:). but, im still curious.

tnx
