COMEDI_SET_OTHER_SOU(3) Comedi reference COMEDI_SET_OTHER_SOU(3)
NAME
comedi_set_other_source - select source signal for something other than a gate or clock
SYNOPSIS
#include <comedilib.h>
int comedi_set_other_source(comedi_t * device, unsigned int subdevice, unsigned int channel, unsigned int other, unsigned int source);
STATUS
alpha
DESCRIPTION
This function allows selection of a source signal for something on a subdevice other than a gate (which uses comedi_set_gate_source) or a
clock (which uses comedi_set_clock_source). The other parameter selects which "other" we are configuring, and is driver-dependent. The
source parameter selects the source we which to use for the "other". If the subdevice does not support configuring its "other" sources on a
per-channel basis, then the channel parameter will be ignored.
As an example, this function is used to select which PFI digital input channels should be used as the A/B/Z signals when running a counter
on an NI M-Series board as a quadrature encoder. The other parameter selects either the A, B, or Z signal, and the source parameter is used
to specify which PFI digital input channel the external A, B, or Z signal is physically connected to.
This function is only useable on subdevices that provide support for the INSN_CONFIG_SET_OTHER_SOURCE configuration instruction.
RETURN VALUE
0 on success, -1 on error.
