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.
