      -S, --protocol-decoder-stack <stack>
      This option allows the user to specify a protocol decoder stack,
      i.e.  the way in which one protocol decoder's output gets piped
      into another protocol decoder. If not specified, the stack  will
      be  set up in the same order in which the protocol decoders were
      given with the --protocol-decoders option.
 
      The decoders are specified by their ID, as shown in  the --ver‐
      sion output. In addition to the -S option, all protocol decoders
      that are used in a stack, must also be specified (together  with
      their options, if any) using the -A parameter.
 
      Example:
 
      $ sigrok-cli -i <file.sr> -A i2c:sda=4:scl=7,rtc8564
    -S i2c,rtc8564
 
      In  this example, the -S option specifies that the output of the
      i2c decoder is piped into the rtc8564 decoder, i.e., the rtc8564
      decoder is stacked on top of the i2c decoder.
 
      The  respective  protocol  decoder options and probe name/number
      assignments must be given using the -P option (you cannot  spec‐
      ify them in the -S option).

      -M, --protocol-decoder-meta <pdname>

      $ 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.

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 -V 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 -V option to see a list of	available  input  for-
	      mats.

	      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 -V 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.

	      Supported formats currently include bits,  hex,  ascii,  binary,
	      vcd, ols, gnuplot, chronovu-la8, csv, and analog.

	      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 --version 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.
