SIGROK-CLI(1) General Commands Manual SIGROK-CLI(1) 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. --list-supported-wiki Show information about supported protocol decoders in MediaWiki syntax. This is generally only used by developers to easily up- date the list of supported protocol decoders in the sigrok wiki. -d, --driver <drivername> Unless doing a global scan, users typically select one of the available drivers. This can speedup program start, and can avoid false matches for ambiguous configurations. Selecting a driver also allows to pass more driver specific options. 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. Notice that colons are used to separate the driver name from the conn option, thus colons cannot be used within the conn option's argument. To se- lect a specific USB device, use either VendorID.ProductID or bus.address: USB VendorID.ProductID example: $ sigrok-cli --driver=uni-t-ut61e:conn=1a86.e008 [...] USB bus.address example: $ sigrok-cli --driver=uni-t-ut61e:conn=4.6 [...] -D, --dont-scan Do not automatically scan for device drivers in the absence of a -d (--driver) specification. -c, --config <deviceoption> A colon-separated list of device options, where each option takes the form key=value. Multiple occurances of the --config option are supported. The first item in the list of options can take the form channel_group=<name> which would override the --channel-group specification for this list of options. Other option lists in other --config occurances are not affected by this list's channel group name. For example, to set the samplerate to 1MHz on a device supported by the fx2lafw driver, you might specify $ sigrok-cli -d fx2lafw --config samplerate=1m [...] Samplerate is an option common to most logic analyzers. The ar- gument specifies the samplerate in Hz. You can also specify the samplerate in kHz, MHz or GHz. The following are all equiva- lent: $ sigrok-cli -d fx2lafw --config samplerate=1000000 [...] $ sigrok-cli -d fx2lafw --config samplerate=1m [...] $ sigrok-cli -d fx2lafw --config "samplerate=1 MHz" [...] These examples specify options within a channel group. The first two are equivalent. $ sigrok-cli -d demo --channel-group Logic --config pat- tern=random [...] $ sigrok-cli -d demo --config channel_group=Logic:pattern=ran- dom [...] $ sigrok-cli -d demo --config samplerate=1m --config chan- nel_group=Logic:pattern=random [...] -i, --input-file <filename> Load input from a file instead of a hardware device. You can specify "-" to use stdin as input. If the --input-format option is not supplied, sigrok-cli attempts to autodetect the file for- mat of the input file. Example for loading a sigrok session file: $ sigrok-cli -i example.sr [...] Example for loading a WAV file (autodetection of input format): $ sigrok-cli -i example.wav [...] Example for loading a VCD file from stdin (autodetection of in- put format): $ cat example.vcd | sigrok-cli -i - [...] -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. Example for loading a binary file with options: $ sigrok-cli -i example.bin -I binary:numchannels=4:samplerate=1mhz [...] -o, --output-file <filename> Save output to a file instead of writing it to stdout. The de- fault format used when saving is the sigrok session file format. This can be changed with the --output-format option. Example for saving data in the sigrok session format: $ sigrok-cli [...] -o example.sr -O, --output-format <format> Set the output format to use. Use the -L (--list-supported) op- tion 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 -O 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 de- fined), followed by a colon. If no format is specified, it de- faults to bits:width=64, like this: 0:11111111 11111111 11111111 11111111 [...] 1:11111111 00000000 11111111 00000000 [...] Example for saving data in the CSV format with options: $ sigrok-cli [...] -o example.csv -O csv:dedup:header=false Notice that boolean options are true when no value gets speci- fied. -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. Examples: $ sigrok-cli -g CH1 [...] $ sigrok-cli -d demo -g Logic -c pattern=graycode [...] Channel group specifications in --get or --config options take precedence over channel group names in --channel-group so that a single sigrok-cli invocation can support the query or manipula- tion of multiple device options which reside in different chan- nel groups. -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 ac- tually 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. Notice that the sigrok-cli application does not support "name matching". Instead it's assumed that the traces in the input stream match the order of the decoder's input signals, or that users explicitly specify the input channel to decoder signal mapping. When multiple decoders are specified in the same -P option, they will be stacked on top of each other in the specified order. Example: $ sigrok-cli -i <file.sr> -P i2c,eeprom24xx $ sigrok-cli -i <file.sr> -P uart:baudrate=31250,midi When multiple -P options are specified, each of them creates one decoder stack, which executes in parallel to other decoder stacks. Example: $ sigrok-cli -i <file.sr> -P uart:tx=D0:rx=D1 -P timing:data=D2 -A, --protocol-decoder-annotations <annotations> By default, all annotation output of all protocol decoders is shown. With this option a specific decoder's annotations can be selected for display, by specifying the decoder ID: $ sigrok-cli -i <file.sr> -P i2c,i2cfilter,edid -A i2c If a protocol decoder has multiple annotation classes, 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 annotation classes by separating them with a colon: $ sigrok-cli -i <file.sr> -P i2c,i2cfilter,edid -A i2c=data-read:data-write Annotation row names will resolve to their respective list of classes. Row and class names can be used in combination. When names are ambiguous then class names take precedence. $ sigrok-cli -i <file.sr> -P i2c -A i2c=addr-data:warnings You can also select multiple protocol decoders, with optionally selected annotation classes each, by separating them with com- mas: $ 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 bi- nary 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 This also works for input files, including optional input format specifications: $ sigrok-cli --input-file <file.sr> --show $ sigrok-cli --input-file <file.vcd> --input-format vcd --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. Multiple variable names can be specified and get separated by colon. The list of variable names optionally can be pre- ceeded by channel_group=<name> which would override the --chan- nel-group specification. Multiple --get occurances are sup- ported in a single sigrok-cli invocation. $ sigrok-cli -d demo --get samplerate:averaging --get chan- nel_group=Logic:pattern --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.
