NAME¶

oneshot - one-shot pulse generator

SYNOPSIS¶

loadrt oneshot [count=N|names=name1[,name2...]]

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¶

oneshot.N (requires a floating-point thread)

Produce output pulses from input edges

PINS¶

oneshot.N.in bit in

Trigger input

oneshot.N.reset bit in

Reset

oneshot.N.out bit out

Active high pulse

oneshot.N.out-not bit out

Active low pulse

oneshot.N.width float in (default: 0)

Pulse width in seconds

oneshot.N.time-left float out

Time left in current output pulse

PARAMETERS¶

oneshot.N.retriggerable bit rw (default: TRUE)

Allow additional edges to extend pulse

oneshot.N.rising bit rw (default: TRUE)

Trigger on rising edge

oneshot.N.falling bit rw (default: FALSE)

Trigger on falling edge
