HAL Component — ONESHOTV2

INSTANTIABLE COMPONENTS — General

All instantiable components can be loaded in two manners

Using loadrt with or without count= | names= parameters as per legacy components
Using newinst, which names the instance and allows further parameters and arguments
primarily pincount= which can set the number of pins created for that instance (where applicable)

NAME

oneshotv2 — one-shot pulse generator

SYNOPSIS

oneshotv2

USAGE SYNOPSIS

loadrt oneshotv2
OR
newinst oneshotv2 <newinstname> [ pincount=N | iprefix=prefix ] [instanceparamX=X | argX=X ]

( args in [ ] denote possible args and parameters, may not be used in all components )

DESCRIPTION

creates a variable-length output pulse when the input changes state. This function needs to run in a thread which supports floating point (typically the servo thread). This means that the pulse length has to be a multiple of that thread period, typically 1mS. For a similar function that can run in the base thread, and which offers higher resolution, see "edge".

FUNCTIONS

oneshotv2.N.funct ( OR <newinstname>.funct (requires a floating-point thread) )

Produce output pulses from input edges
