12 int comedi_data_read_delayed (comedi_t * device, unsigned int subde‐
13 vice, unsigned int channel, unsigned int range, unsigned int aref,
14 lsampl_t * data, unsigned int nanosec);

17 Similar to comedi_data_read() except it will wait for the specified
18 number of nanoseconds between setting the input channel and taking a
19 sample. For analog inputs, most boards have a single analog to digital
20 converter which is multiplexed to be able to read multiple channels.
21 If the input is not allowed to settle after the multiplexer switches
22 channels, the reading will be inaccurate. This function is useful for
23 allowing a multiplexed analog input to settle when switching channels.

25 Although the settling time is specified in nanoseconds, the actual set‐
26 tling time will be rounded up to the nearest microsecond.
