slight update to pulseIn() function documentation

I found this in the source code for pulseIn():
"/* Measures the length (in microseconds) of a pulse on the pin; state is HIGH

  • or LOW, the type of pulse to measure. Works on pulses from 2-3 microseconds
  • to 3 minutes in length, but must be called at least a few dozen microseconds
  • before the start of the pulse. */"

However, this is not in the documentation here: http://arduino.cc/en/Reference/PulseIn

Please update the documentation to contain the above information, which is critical for certain applications. The line I especially found useful from the source code is that the function **“must be called at least a few dozen microseconds before the start of the pulse.” **

For your question, please create a new topic under Project Guidance then edit your post above and remove the question.

Done. My new thread and my project question is located here: http://forum.arduino.cc//index.php?topic=196592.0

Thank you.

Do you think my suggestion will actually get added to the Arduino reference page for pulseIn?

I don't know.
