Examples
ao_waveform:
You need a device (and driver) capable of streaming analog output,
which currently is some of the members of the NI AT-MIO and PCI-MIO
E series. Creates a sine wave on an analog output channel.
cmd:
Asynchronous input.
eeprom_dump:
Dumps the EEPROM of a card, if it has one. Useful for debugging
devices/drivers.
info:
Displays some information that Comedi knows about a device.
inp:
Simple input demo. Reads one sample from an input line.
inpn:
Slightly more complicated input demo. (It has a for() loop.)
Reads each channel on a subdevice, at every possible input
range, and converts the data to a voltage.
insn:
Example showing how to use instructions directly.
sv:
Similar to inp, but measures the input using the comedi_sv_*()
functions, which average many samples to try to get a more accurate
estimate of the actual input.

tut2:
Tutorial examples.
Many of these demos are linked with the file main.c, which parses
command line options. Some options don't make sense with all programs.
The options are:
-a <aref> uses analog reference <aref> (default: 0)
-c <chan> uses channel <chan>
-s <subd> uses subdevice <subd>
-r <range> uses voltage range <range>
-f <file> uses device file <file> (default: /dev/comedi0)
-v verbose
-d set analog reference to differential
-g set analog reference to ground
-o set analog reference to other
-m set analog reference to common
