convert number to low/high byte (hex) for serial
Dec 2nd, 2008, 3:16am  
hi, I'm having difficulties while talking to a servo controller via serial connection:
everything works fine as far as understanding the protocoll and adressing single servos with a specific position, but to move the servos interactively I need to take the position of e.g. a slider and convert it to a hex-number which then needs to be send out as "low byte" and "high byte".
Could anybody please help me with the conversion and the seperation of the hex number into the two parts?!

would be so great and thanks alot

Basically, when I need to send 4 byte integer to serial port I do something like that:
   myPort.write(val>>24);
   myPort.write(val>>16);
   myPort.write(val>>8);
   myPort.write(val);
