Serial.parseInt()

parseInt()

Description

Looks for the next valid integer in the incoming serial. The function terminates if it times out (see Serial.setTimeout()).

Serial.parseInt() inherits from the Stream utility class.

In particular:

• Initial characters that are not digits or a minus sign, are skipped;
  

• Parsing stops when no characters have been read for a configurable time-out value, or a non-digit is read;
  

• If no valid digits were read when the time-out (see Serial.setTimeout()) occurs, 0 is returned;

Syntax

Serial.parseInt()
Serial.parseInt(char skipChar)

Parameters

Serial: serial port object. See the list of available serial ports for each board on the Serial main page.
skipChar: used to skip the indicated char in the search. Used for example to skip thousands divider.

Returns

long : the next valid integer
