DelayUs

Syntax

DelayUs Length

Overview

Delay execution for Length X microseconds (us). Delays may be up to 65535us (65.535 milliseconds) long.

Parameters

Length can be a constant, variable, or expression.

Example

Device = 18F25K20
Declare Xtal = 16

Dim MyByte as Byte = 50
Dim MyWord as Word = 1000

DelayUs 1               ' Delay for 1us
DelayUs 100             ' Delay for 100us
DelayUs MyByte          ' Delay for 50us
DelayUs MyWord          ' Delay for 1000us
DelayUs MyWord + 10   ' Delay for 1010us

Notes

DelayUs is oscillator independent, as long as you inform the compiler of the crystal frequency to use, using the Xtal directive.

If a constant is used as Length, then delays down to 1us can be achieved, however, if a Variable is used as the Length parameter, then there's a minimum delay time depending on the frequency of the crystal used: -
