DELAY
From MCS Wiki AVR
Contents |
Action
Delay program execution for a short time.
Syntax
DELAY
Remarks
Use DELAY to wait for a short time.
The delay time is ca. 1000 microseconds.
Interrupts that occur frequently and/or take a long time to process, will let the delay last longer.
When you need a very accurate delay, you need to use a timer.
