Prolonged discussions of marginal utility. What a luxury isn't it?
Lefty, you're good at performance calculations.
Any estimates on the Serial.print vs Serial.write runtime overhead? Of academic interest and pure curiosity, at this point...
Maybe, but it's not unlike the use of Arduino pin numbering Vs direct port I/O access. The first is more readable and portable across the various AVR chips but it does carry a speed penalty compared to the second method. So it's nice to be educated about both methods, their trade-offs so that one's application can point to the best method needed.Lefty
