parseInt()Looks for the next valid integer in the incoming serial stream. 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;
Z-Uno also supports UART0, UART1 communication — Serial0.perseInt(), Serial1.parseInt() skipChar used to skip the indicated char in the search. Used for example to skip thousands divider.
