NAME
       sigrok-cli - Command-line client for the sigrok software

SYNOPSIS
       sigrok-cli [OPTIONS] [COMMAND]

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

       It cannot display graphical output, but	is  still  sufficient  to  run
       through the whole process of hardware initialization, acquisition, pro-
       tocol decoding 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
       -h, --help
	      Show a help text and exit.

       -V, --version
	      Show sigrok-cli version and the versions of libraries used.

       -L, --list-supported
	      Show information about supported hardware  drivers,  input  file
	      formats, output file formats, and protocol decoders.

       -d, --driver <drivername>
	      A  driver  must always be selected (unless doing a global scan).
	      Use the -L (--list-supported) option to get a list of  available
	      drivers.

	      Drivers  can  take  options,  in the form key=value separated by
	      colons.

	      Drivers communicating with hardware via  a  serial  port	always
	      need  the port specified as the conn option. For example, to use
	      the Openbench Logic Sniffer:

		$ sigrok-cli --driver=ols:conn=/dev/ttyACM0

	      Some USB devices don't use a unique VendorID/ProductID  combina-
	      tion,  and  thus need that specified as well. This also uses the
	      conn option, using either VendorID.ProductID or bus.address:

		$ sigrok-cli --driver=uni-t-ut61e:conn=1a86.e008

       -c, --config <device>
	      A colon-separated list of  device  options,  where  each	option
	      takes the form key=value.  For example, to set the samplerate to
	      1MHz on a device supported by  the  fx2lafw  driver,  you  might
	      specify

		$ sigrok-cli --driver=fx2lafw --config samplerate=1m

	      Samplerate  is  an  option  common  to most logic analyzers. The
	      argument specifies the samplerate in Hz. You  can  also  specify
	      the samplerate in kHz, MHz or GHz.  The following are all equiv-
	      alent:

		$ sigrok-cli --driver fx2lafw --config samplerate=1000000

		$ sigrok-cli --driver fx2lafw --config samplerate=1m

		$ sigrok-cli --driver fx2lafw --config "samplerate=1 MHz"

       -i, --input-file <filename>
	      Load input from a file instead of  a  hardware  device.  If  the
	      --input-format  option  is  not supplied, sigrok-cli attempts to
	      autodetect the file format of the input file.

       -I, --input-format <format>
	      When loading an input file, assume it's in the specified format.
	      If  this	option	is not supplied (in addition to --input-file),
	      sigrok-cli attempts to autodetect the file format of  the  input
	      file.  Use  the  -L  (--list-supported)  option to see a list of
	      available input formats.

	      The format name may optionally be followed by a  colon-separated
	      list of options, where each option takes the form key=value.

       -o, --output-file <filename>
	      Save  output  to	a  file  instead  of writing it to stdout. The
	      default format used when saving is the sigrok session file  for-
	      mat. This can be changed with the --output-format option.

       -O, --output-format <formatname>
	      Set  the	output	format	to  use. Use the -L (--list-supported)
	      option to see a list of available output formats.

	      The format name may optionally be followed by a  colon-separated
	      list of options, where each option takes the form key=value.

	      For  example, the bits or hex formats, for an ASCII bit or ASCII
	      hexadecimal display, can take a "width" option,  specifying  the
	      number   of   samples  (in  bits)  to  display  per  line.  Thus
	      hex:width=128 will display 128 bits per line, in hexadecimal:

	       0:ffff ffff ffff ffff ffff ffff ffff ffff
	       1:ff00 ff00 ff00 ff00 ff00 ff00 ff00 ff00

	      The lines always start with the  channel	number	(or  name,  if
	      defined),  followed  by  a  colon. If no format is specified, it
	      defaults to bits:width=64, like this:

	       0:11111111 11111111 11111111 11111111 [...]
	       1:11111111 00000000 11111111 00000000 [...]

       -C, --channels <channellist>
	      A comma-separated list of channels to be used in the session.

	      Note that sigrok always names  the  channels  according  to  how
	      they're  shown  on  the enclosure of the hardware. If your logic
	      analyzer numbers the channels 0-15, that's how you must  specify
	      them  with  this option. An oscilloscope's channels would gener-
	      ally be referred to as "CH1", "CH2", and so on.  Use the	--show
	      option to see a list of channel names for your device.

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

	      Example:

		$ sigrok-cli --driver fx2lafw --samples 100
			     --channels 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,CS=MISO will set the name of channel 1 to MISO.

       -g, --channel-group <channel group>
	      Specify the channel group to operate on.

	      Some  devices  organize  channels  into  groups, the settings of
	      which can only be changed  as  a	group.	The  list  of  channel
	      groups, if any, is displayed with the --show command.

       -t, --triggers <triggerlist>
	      A  comma-separated  list	of triggers to use, of the form <chan-
	      nel>=<trigger>.  You can use the name or number of the  channel,
	      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.
	      e: Any kind of change on a pin (either a	rising	or  a  falling
	      edge).

	      Not  every  device  supports all of these trigger types. Use the
	      --show command to see which triggers your device supports.

       -w, --wait-trigger
	      Don't output any sample data (even  if  it's  actually  received
	      from the hardware) before the trigger condition is met. In other
	      words, do not output any pre-trigger data. This option is useful
	      if  you  don't  care about the data that came before the trigger
	      (but the hardware delivers this data to sigrok nonetheless).

       -P, --protocol-decoders <list>
	      This option allows the user to specify a comma-separated list of
	      protocol	decoders  to be used in this session. The decoders are
	      specified by their ID, as shown  in  the	-L  (--list-supported)
	      output.

	      Example:

	       $ sigrok-cli -i <file.sr> -P i2c

	      Each protocol decoder can optionally be followed by a colon-sep-
	      arated list  of  options,  where	each  option  takes  the  form
	      key=value.

	      Example:

	       $ sigrok-cli -i <file.sr>
			    -P uart:baudrate=115200:parity_type=odd

	      The  list  of supported options depends entirely on the protocol
	      decoder. Every protocol decoder has different  options  it  sup-
	      ports.

	      Any  "options"  specified  for  a protocol decoder which are not
	      actually supported options, will be interpreted as being channel
	      name/number assignments.

	      Example:

	       $ sigrok-cli -i <file.sr>
			    -P spi:wordsize=9:miso=1:mosi=5:clk=3:cs=0

	      In this example, wordsize is an option supported by the spi pro-
	      tocol decoder. Additionally, the user tells sigrok to decode the
	      SPI  protocol  using channel 1 as MISO signal for SPI, channel 5
	      as MOSI, channel 3 as CLK, and channel 0 as CS# signal.

       -A, --protocol-decoder-annotations <annotations>
	      By default, only the stack's topmost protocol decoder's  annota-
	      tion output is shown. With this option another decoder's annota-
	      tion can be selected for display, by specifying its ID:

	       $ sigrok-cli -i <file.sr> -P i2c,i2cfilter,edid -A i2c

	      If a protocol decoder has multiple  annotations,	you  can  also
	      specify  which  one  of  them  to  show  by specifying its short
	      description like this:

	       $ sigrok-cli -i <file.sr> -P i2c,i2cfilter,edid
			    -A i2c=data-read

	      Select multiple annotations by separating them with a colon:

	       $ sigrok-cli -i <file.sr> -P i2c,i2cfilter,edid
			    -A i2c=data-read:data-write

	      You can also select multiple protocol decoders, with an optional
	      selected annotation each, by separating them with commas:

	       $ sigrok-cli -i <file.sr> -P i2c,i2cfilter,edid
			    -A i2c=data-read:data-write,edid

       -M, --protocol-decoder-meta <pdname>
	      When given, show protocol decoder meta output instead of annota-
	      tions.  The argument is the name of the decoder whose meta  out-
	      put to show.

	       $ sigrok-cli -i <file.sr> -M i2c

	      Not every decoder generates meta output.

       -B, --protocol-decoder-binary <binaryspec>
	      When  given,  decoder  "raw" data of various kinds is written to
	      stdout instead of annotations (this could be raw binary UART/SPI
	      bytes,  or  WAV  files, PCAP files, PNG files, or anything else;
	      this is entirely dependent on the  decoder  and  what  kinds  of
	      binary output make sense for that decoder).

	      No  other  information is printed to stdout, so this is suitable
	      for piping into other programs or saving to a file.

	      Protocol decoders that support binary output publish a  list  of
	      binary classes, for example the UART decoder might have "TX" and
	      "RX". To select TX for output, the argument to this option would
	      be:

	       $ sigrok-cli -i <file.sr> -B uart=tx

	      If only the protocol decoder is specified, without binary class,
	      all classes are written to stdout:

	       $ sigrok-cli -i <file.sr> -B uart

	      (this is only useful in rare cases, generally you would  specify
	      a certain binary class you're interested in)

	      Not every decoder generates binary output.

       --protocol-decoder-samplenum
	      When  given,  decoder  annotations  will include sample numbers,
	      too.  This allows consumers to receive machine  readable	timing
	      information.

       -l, --loglevel <level>
	      Set  the	libsigrok  and libsigrokdecode loglevel. At the moment
	      sigrok-cli doesn't support setting the  two  loglevels  indepen-
	      dently.  The  higher  the  number, the more debug output will be
	      printed. Valid loglevels are:

	      0   None
	      1   Error
	      2   Warnings
	      3   Informational
	      4   Debug
	      5   Spew

       --show
	      Show information about the selected option. For example, to  see
	      options for a connected fx2lafw device:

	       $ sigrok-cli --driver fx2lafw --show

	      In  order to properly get device options for your hardware, some
	      drivers might need a serial port specified:

	       $ sigrok-cli --driver ols:conn=/dev/ttyACM0 --show

	      This also works for protocol decoders, input modules and	output
	      modules:

	       $ sigrok-cli --protocol-decoders i2c --show
	       $ sigrok-cli --input-format csv --show
	       $ sigrok-cli --output-format bits --show

       --scan Scan for devices that can be detected automatically.

	      Example:

	       $ sigrok-cli --scan
	       The following devices were found:
	       demo - Demo device with 12 channels: D0 D1 D2 D3 D4 D5 D6 D7 A0
	      A1 A2 A3
	       fx2lafw:conn=3.26 - CWAV USBee SX with 8 channels: 0 1 2 3 4  5
	      6 7

	      However,	not  all devices are auto-detectable (e.g. serial port
	      based ones).  For those you'll have to provide  a  conn  option,
	      see above.

	       $ sigrok-cli --driver digitek-dt4000zc:conn=/dev/ttyUSB0 --scan
	       The following devices were found:
	       Digitek DT4000ZC with 1 channel: P1

       --time <ms>
	      Sample for <ms> milliseconds, then quit.

	      You can optionally follow the number by s to specify the time to
	      sample in seconds.

	      For example, --time 2s will sample for two seconds.

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

	      You can optionally follow the number by k, m, or	g  to  specify
	      the  number  of samples in kilosamples, megasamples, or gigasam-
	      ples, respectively.

	      For example, --samples 3m will acquire 3000000 samples.

       --frames <numframes>
	      Acquire <numframes> frames, then quit.

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

       --get <variable>
	      Get the value of <variable> from the specified device and  print
	      it.

       --set  Set  one	or  more variables specified with the --config option,
	      without doing any acquisition.

EXAMPLES
       In order to get exactly 100 samples  from  the  connected  fx2lafw-sup-
       ported logic analyzer hardware, run the following command:

	 sigrok-cli --driver fx2lafw --samples 100

       If you want to sample data for 3 seconds (3000 ms), use:

	 sigrok-cli --driver fx2lafw --time 3000

       Alternatively, you can also use:

	 sigrok-cli --driver fx2lafw --time 3s

       To  capture  data  from	the first 4 channels using the Openbench Logic
       Sniffer lasting 100ms at 10 MHz starting at the trigger condition
	      0:high, 1:rising, 2:low, 3:high, use:

       sigrok-cli --driver ols:conn=/dev/ttyACM0 --config samplerate=10m \
	      --output-format bits --channels 0-3 --wait-trigger \
	      --triggers 0=1,1=r,2=0,3=1 --time 100

       To turn on internal logging on a Lascar EL-USB series device:

       sigrok-cli --driver lascar-el-usb:conn=10c4.0002 \
	      --config datalog=on --set

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