parseInt()

Description

parseInt() returns the first valid (long) integer number from the serial buffer. Characters that are not integers (or the minus sign) are skipped.

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;

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

Syntax

Serial.parseInt()

Serial.parseInt(char skipChar)

Parameters

skipChar: used to skip the indicated char in the search. Used for example to skip thousands divider.

Returns

long
