5: BASIC Stamp Command Reference – PAUSE

PAUSE

2 2 PAUSE Period
sx p
Function
Pause the program (do nothing) for the specified Period.
• Period is a variable/constant/expression (0 – 65535) that specifies
the duration of the pause.
millisecond.
Explanation
PAUSE delays the execution of the next program instruction for the
specified number of milliseconds. For example:
Flash:
LOW 0
PAUSE 100
HIGH 0
PAUSE 100
GOTO Flash
This code causes pin 0 to go low for 100 ms, then high for 100 ms. The
delays produced by PAUSE are as accurate as the ceramic-resonator time
base (on the BASIC Stamp modules), ±1 percent. When you use PAUSE in
timing-critical applications, keep in mind the relatively low speed of the
PBASIC interpreter. This is the time required for the BASIC Stamp to read
and interpret an instruction stored in the EEPROM.
