DESCRIPTION
       sigrok-cli  is  a  cross-platform  command  line utility for the sigrok
       logic analyzer software.

       The command-line frontend for sigrok cannot display  graphical  output,
       but  is  still  sufficient to run through the whole process of hardware
       initialization, acquisition, protocol analysis and saving the session.

       It is useful for running on remote or embedded systems, netbooks, PDAs,
       and  for  various  other  use-cases. It can display samples on standard
       output or save them in various file formats.

OPTIONS
       -V, --version
              Show version, driver and module information.

       -D, --list-devices
              List all logic analyzer devices found on the system.

       -d, --device <devid>
              The device to use for acquisition, specified by ID  as  reported
              by --list-devices.

       -p, --probes <probelist>
              A comma-separated list of probes to be used in the session.

              The  default is to use all the probes available on a device. You
              can name a probe like this: 1=CLK.  A range of probes  can  also
              be given, in the form 1-5.

              Example:

               $ sigrok-cli --samples 100 --probes 1=CLK,2-4,7
               CLK:11111111 11111111 11111111 11111111 [...]
                 2:11111111 11111111 11111111 11111111 [...]
                 3:11111111 11111111 11111111 11111111 [...]
                 4:11111111 11111111 11111111 11111111 [...]
                 7:11111111 11111111 11111111 11111111 [...]

              The  comma-separated  list is processed from left to right, i.e.
              items farther to the right override previous items. For  example
              1=CS,1=MISO will set the name of probe 1 to MISO.

              Also,  while  5=MOSI,6=MISO will only select probes 5 and 6, and
              set  their  names  to  MISO   and   MOSI,   the   command   line
              5=MOSI,6=MISO,1-8  will select probes 1-8 (including 5 and 6, of
              course), but the names specified for probes  5  and  6  will  be
              reset to the defaults by the 1-8 probe selection.

       -t, --triggers <triggerlist>
              A   comma-separated  list  of  triggers  to  use,  of  the  form
              <probe>=<trigger>.  You can use the name or number of the probe,
              and the trigger itself is a series of characters:

              0 or 1: A low or high value on the pin.
              r  or  f: A rising or falling value on the pin. An r effectively
              corresponds to 01.
              c: Any kind of change on a pin.

              Not every device supports all of these trigger types. Use the -d
              <device-id>  argument  (with  no  other  arguments) to see which
              triggers your device supports.

       -o, --device-option <devopt>
              Set a device-specific option. The argument  takes  the  form  of
              option=value.   A common option is samplerate, with the argument
              being the samplerate in Hz. You can also specify the sample rate
              in kHz, MHz or GHz. The following are all equivalent:

               sigrok-cli --samples 100 -o samplerate=1000000
               sigrok-cli --samples 100 -o samplerate=1m
               sigrok-cli --samples 100 -o "samplerate=1 MHz"

              The  --device-option  argument  can  be  used  multiple times as
              needed.

       -I, --input-file <filename>
              Load input from a file instead of a device.

       -f, --format <formatname>
              Set the output format to use.

              Supported formats currently include bits,  hex,  ascii,  binary,
              vcd, ols, gnuplot, and analog.

              The bits or hex formats, for an ASCII bit display or ASCII hexa‐
              decimal display, can be optionally followed by a length argument
              specifying  the  number  of samples (in bits). Thus hex128 would
              display 128 bits per line, in hexadecimal:

               1:ffff ffff ffff ffff ffff ffff ffff ffff
               2:ff00 ff00 ff00 ff00 ff00 ff00 ff00 ff00

              The lines always start  with  the  probe  number  (or  name,  if
              defined),  followed  by  a  colon. If no format is specified, it
              defaults to bits64, like this:

               1:11111111 11111111 11111111 11111111 [...]
               2:11111111 00000000 11111111 00000000 [...]

       --time <ms>
              Sample for <ms> milliseconds, then quit. You can optionally fol‐
              low  the  number  by  s to state the number of seconds to sample
              instead. For example, --time 2s will sample for two seconds.

       --samples <numsamples>
              Acquire <numsamples> samples, then quit.

       --continuous
              Sample continuously until stopped. Not all devices support this.

       -h, --help
              Show a help text and exit.

EXAMPLES
       In order to get exactly 100 samples from the (only) detected logic ana‐
       lyzer hardware, run the following command:

         sigrok-cli --samples 100

       If you want to sample data for 3 seconds, use:

         sigrok-cli --time 3000

       Alternatively, you can also use:

         sigrok-cli --time 3s

       To  capture  data from 4 probes lasting 100ms at 10 MHz starting at the
       trigger condition 1:high, 2:rising, 3:low, 4:high, use:

         sigrok-cli -f bits -p 1-4 --time 100 -o samplerate=10m \
                    --wait-trigger --triggers 1=1,2=r,3=0,4=1

EXIT STATUS
       sigrok-cli exits with 0 on success, 1 on most failures.
