NAME

7       a gate or clock

SYNOPSIS

10       #include <comedilib.h>
11
12       int comedi_set_other_source(comedi_t * device, unsigned int subdevice,
13                                   unsigned int channel, unsigned int other,
14                                   unsigned int source);

STATUS

DESCRIPTION

20       This function allows selection of a source signal for something on a
21       subdevice other than a gate (which uses comedi_set_gate_source) or a
22       clock (which uses comedi_set_clock_source). The other parameter selects
23       which “other” we are configuring, and is driver-dependent. The source
24       parameter selects the source we which to use for the “other”. If the
25       subdevice does not support configuring its “other” sources on a
26       per-channel basis, then the channel parameter will be ignored.
27
28       As an example, this function is used to select which PFI digital input
29       channels should be used as the A/B/Z signals when running a counter on
30       an NI M-Series board as a quadrature encoder. The other parameter
31       selects either the A, B, or Z signal, and the source parameter is used
32       to specify which PFI digital input channel the external A, B, or Z
33       signal is physically connected to.
34
35       This function is only useable on subdevices that provide support for
36       the INSN_CONFIG_SET_OTHER_SRC configuration instruction.

RETURN VALUE

39       0 on success, -1 on error.
