Arduino Program Timing

PHOTO 1 
Each of the digitalWrite() functions producing this pulse requires 5.1 µs, roughly 50 instructions, on the 16 MHz ATmega328 microcontroller. The Arduino loop() adds 0.40 µs to the low portion of the waveform.

Ed Nisely explains how output pulses can reveal the progress of invisible firmware routines. After presenting a straightforward way to instrument your code, he covers the detailed timing produced by Arduino statements and functions. While writing the Arduino program for … Continue reading
