3 | sigrok\-cli \- Command-line client for the sigrok software | |
4 | .SH "SYNOPSIS" | |
5 | .B sigrok\-cli [OPTIONS] [COMMAND] | |
6 | .SH "DESCRIPTION" | |
7 | \fBsigrok\-cli\fP is a cross-platform command line utility for the | |
8 | \fBsigrok\fP software. | |
9 | .PP | |
10 | It cannot display graphical output, but is still sufficient to run through | |
11 | the whole process of hardware initialization, acquisition, protocol decoding | |
12 | and saving the session. | |
13 | .PP | |
14 | It is useful for running on remote or embedded systems, netbooks, PDAs, | |
15 | and for various other use-cases. It can display samples on standard output or | |
16 | save them in various file formats. | |
17 | .SH OPTIONS | |

19 | .B "\-h, \-\-help" | |
20 | Show a help text and exit. | |
21 | .TP | |

23 | Show | |
24 | .B sigrok-cli | |
25 | version, and information about supported hardware drivers, input file | |
26 | formats, output file formats, and protocol decoders. | |
27 | .TP | |
28 | \fB\-d, \-\-driver\fP <drivername> | |
29 | A driver must always be selected (unless doing a global scan). Use the | |
30 | \fB-V\fP option to get a list of available drivers. | |
31 | .sp | |
32 | Drivers can take options, in the form \fBkey=value\fP | |
33 | separated by colons. | |
34 | .sp | |
35 | Drivers communicating with hardware via a serial port always need the port | |
36 | specified as the \fBconn\fP option. For example, to use the | |
37 | Openbench Logic Sniffer: | |
38 | .sp | |
39 | .RB " $ " "sigrok\-cli \-\-driver=ols:conn=/dev/ttyACM0" | |
40 | .sp | |
41 | Some USB devices don't use a unique VendorID/ProductID combination, and thus | |
42 | need that specified as well. This also uses the \fBconn\fP option, using | |
43 | either \fBVendorID.ProductID\fP or \fBbus.address\fP: | |
44 | .sp | |
45 | .RB " $ " "sigrok\-cli \-\-driver=uni-t-ut61e:conn=1a86.e008" | |
46 | .TP | |
47 | .BR "\-c, \-\-config " <device> | |
48 | A colon-separated list of device options, where each option takes the form | |
49 | .BR key=value . | |
50 | For example, to set the samplerate to 1MHz on a device supported by the | |
51 | fx2lafw driver, you might specify | |
52 | .sp | |
53 | .RB " $ " "sigrok\-cli \-\-driver=fx2lafw \-\-config samplerate=1m" | |
54 | .sp | |
55 | Samplerate is an option common to most logic analyzers. The argument specifies | |
56 | the samplerate in Hz. You can also specify the samplerate in kHz, MHz or GHz. | |
57 | The following are all equivalent: | |
58 | .sp | |
59 | .RB " $ " "sigrok\-cli \-\-driver fx2lafw \-\-config samplerate=1000000" | |
60 | .sp | |
61 | .RB " $ " "sigrok\-cli \-\-driver fx2lafw \-\-config samplerate=1m" | |
62 | .sp | |
63 | .RB " $ " "sigrok\-cli \-\-driver fx2lafw \-\-config \(dqsamplerate=1 MHz\(dq" | |
64 | .TP | |
65 | .BR "\-i, \-\-input\-file " <filename> | |
66 | Load input from a file instead of a hardware device. If the | |
67 | .B \-\-input\-format | |
68 | option is not supplied, sigrok-cli attempts to autodetect the file format of | |
69 | the input file. | |
70 | .TP | |
71 | .BR "\-I, \-\-input\-format " <format> | |
72 | When loading an input file, assume it's in the specified format. If this | |
73 | option is not supplied (in addition to | |
74 | .BR \-\-input\-file ), | |
75 | sigrok-cli attempts to autodetect the file format of the input file. Use the | |
76 | .B \-V | |
77 | option to see a list of available input formats. | |
78 | .sp | |
79 | The format name may optionally be followed by a colon-separated list of | |
80 | options, where each option takes the form | |
81 | .BR "key=value" . | |
82 | .TP | |
83 | .BR "\-o, \-\-output\-file " <filename> | |
84 | Save output to a file instead of writing it to stdout. The default format | |
85 | used when saving is the sigrok session file format. This can be changed with | |
86 | the | |
87 | .B \-\-output\-format | |
88 | option. | |
89 | .TP | |
90 | .BR "\-O, \-\-output\-format " <formatname> | |
91 | Set the output format to use. Use the | |
92 | .B \-V | |
93 | option to see a list of available output formats. | |
94 | .sp | |
95 | The format name may optionally be followed by a colon-separated list of | |
96 | options, where each option takes the form | |
97 | .BR "key=value" . | |
98 | .sp | |
99 | Supported formats currently include | |
100 | .BR bits , | |
101 | .BR hex , | |
102 | .BR ascii , | |
103 | .BR binary , | |
104 | .BR vcd , | |
105 | .BR ols , | |
106 | .BR gnuplot , | |
107 | .BR chronovu-la8 , | |
108 | .BR csv ", and" | |
109 | .BR analog . | |
110 | .sp | |
111 | The | |
112 | .B bits | |
113 | or | |
114 | .B hex | |
115 | 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 | |
116 | .B hex:width=128 | |
117 | will display 128 bits per line, in hexadecimal: | |
118 | .sp | |
119 | 0:ffff ffff ffff ffff ffff ffff ffff ffff | |
120 | 1:ff00 ff00 ff00 ff00 ff00 ff00 ff00 ff00 | |
121 | .sp | |
122 | The lines always start with the channel number (or name, if defined), followed by a colon. If no format is specified, it defaults to | |
123 | .BR bits:width=64 , | |
124 | like this: | |
125 | .sp | |
126 | 0:11111111 11111111 11111111 11111111 [...] | |
127 | 1:11111111 00000000 11111111 00000000 [...] | |
128 | .TP | |
129 | .BR "\-C, \-\-channels " <channellist> | |
130 | A comma-separated list of channels to be used in the session. | |
131 | .sp | |
132 | Note that sigrok always names the channels according to how they're shown on | |
133 | the enclosure of the hardware. If your logic analyzer numbers the channels 0-15, | |
134 | that's how you must specify them with this option. An oscilloscope's channels | |
135 | would generally be referred to as "CH1", "CH2", and so on. | |
136 | Use the \fB\-\-show\fP option to see a list of channel names for your device. | |
137 | .sp | |
138 | The default is to use all the channels available on a device. You can name | |
139 | a channel like this: | |
140 | .BR "1=CLK" . | |
141 | A range of channels can also be given, in the form | |
142 | .BR "1\-5" . | |
143 | .sp | |
144 | Example: | |
145 | .sp | |
146 | .RB " $ " "sigrok\-cli \-\-driver fx2lafw \-\-samples 100" | |
147 | .br | |
148 | .B " \-\-channels 1=CLK,2\-4,7" | |
149 | .br | |
150 | CLK:11111111 11111111 11111111 11111111 [...] | |
151 | 2:11111111 11111111 11111111 11111111 [...] | |
152 | 3:11111111 11111111 11111111 11111111 [...] | |
153 | 4:11111111 11111111 11111111 11111111 [...] | |
154 | 7:11111111 11111111 11111111 11111111 [...] | |
155 | .sp | |
156 | The comma-separated list is processed from left to right, i.e. items farther | |
157 | to the right override previous items. For example | |
158 | .B "1=CS,CS=MISO" | |
159 | will set the name of channel 1 to | |
160 | .BR "MISO" . | |
161 | .TP | |
162 | .BR "\-g, \-\-channel\-group "<channel\ group> | |
163 | Specify the channel group to operate on. | |
164 | ||
165 | Some devices organize channels into groups, the settings of which can | |
166 | only be changed as a group. The list of channel groups, if any, is displayed | |
167 | with the \fB\-\-show\fP command. | |
168 | .TP | |
169 | .BR "\-t, \-\-triggers " <triggerlist> | |
170 | A comma-separated list of triggers to use, of the form | |
171 | .BR "<channel>=<trigger>" . | |
172 | You can use the name or number of the channel, and the trigger itself is a | |
173 | series of characters: | |
174 | .sp | |
175 | .BR "0 or 1" : | |
176 | A low or high value on the pin. | |
177 | .br | |
178 | .BR "r or f" : | |
179 | A rising or falling value on the pin. An | |
180 | .B r | |
181 | effectively corresponds to | |
182 | .BR 01 . | |
183 | .br | |
184 | .BR "e" : | |
185 | Any kind of change on a pin (either a rising or a falling edge). | |
186 | .sp | |
187 | Not every device supports all of these trigger types. Use the \fB\-\-show\fP | |
188 | command to see which triggers your device supports. | |
189 | .TP | |
190 | .BR "\-w, \-\-wait-trigger" | |
191 | Don't output any sample data (even if it's actually received from the | |
192 | hardware) before the trigger condition is met. In other words, do not output | |
193 | any pre-trigger data. This option is useful if you don't care about the data | |
194 | that came before the trigger (but the hardware delivers this data to sigrok | |
195 | nonetheless). | |
196 | .TP | |
197 | .BR "\-P, \-\-protocol\-decoders " <list> | |
198 | This option allows the user to specify a comma-separated list of protocol | |
199 | decoders to be used in this session. The decoders are specified by their | |
200 | ID, as shown in the | |
201 | .B \-\-version | |
202 | output. | |
203 | .sp | |
204 | Example: | |
205 | .sp | |
206 | $ | |
207 | .B "sigrok\-cli \-i <file.sr> \-P i2c" | |
208 | .sp | |
209 | Each protocol decoder can optionally be followed by a colon-separated list | |
210 | of options, where each option takes the form | |
211 | .BR "key=value" . | |
212 | .sp | |
213 | Example: | |
214 | .sp | |
215 | $ | |
216 | .B "sigrok\-cli \-i <file.sr> " | |
217 | .br | |
218 | .B " \-P uart:baudrate=115200:parity_type=odd" | |
219 | .sp | |
220 | The list of supported options depends entirely on the protocol decoder. Every | |
221 | protocol decoder has different options it supports. | |
222 | .sp | |
223 | Any "options" specified for a protocol decoder which are not actually | |
224 | supported options, will be interpreted as being channel name/number assignments. | |
225 | .sp | |
226 | Example: | |
227 | .sp | |
228 | $ | |
229 | .B "sigrok\-cli \-i <file.sr>" | |
230 | .br | |
231 | .B " \-P spi:wordsize=9:miso=1:mosi=5:clk=3:cs=0" | |
232 | .sp | |
233 | In this example, | |
234 | .B wordsize | |
235 | is an option supported by the | |
236 | .B spi | |
237 | protocol decoder. Additionally, the user tells sigrok to decode the SPI | |
238 | protocol using channel 1 as MISO signal for SPI, channel 5 as MOSI, channel 3 | |
239 | as CLK, and channel 0 as CS# signal. | |
240 | .TP | |
241 | .BR "\-S, \-\-protocol\-decoder\-stack " <stack> | |
242 | This option allows the user to specify a protocol decoder stack, i.e. | |
243 | the way in which one protocol decoder's output gets piped into another | |
244 | protocol decoder. If not specified, the stack will be set up in the same | |
245 | order in which the protocol decoders were given with the | |
246 | .B \-\-protocol-decoders | |
247 | option. | |
248 | .sp | |
249 | The decoders are specified by their ID, as shown in the | |
250 | .B \-\-version | |
251 | output. In addition to the | |
252 | .B \-S | |
253 | option, all protocol decoders that are used in a stack, must also be specified | |
254 | (together with their options, if any) using the | |
255 | .B \-P | |
256 | parameter. | |
257 | .sp | |
258 | Example: | |
259 | .sp | |
260 | $ | |
261 | .B "sigrok\-cli \-i <file.sr> \-P i2c:sda=4:scl=7,rtc8564" | |
262 | .br | |
263 | .B " \-S i2c,rtc8564" | |
264 | .sp | |
265 | In this example, the | |
266 | .B \-S | |
267 | option specifies that the output of the | |
268 | .BR i2c " decoder" | |
269 | is piped into the | |
270 | .BR rtc8564 " decoder," | |
271 | i.e., the | |
272 | .BR rtc8564 " decoder" | |
273 | is stacked on top of the | |
274 | .BR i2c " decoder." | |
275 | .sp | |
276 | The respective protocol decoder options and channel name/number assignments | |
277 | must be given using the | |
278 | .B \-P | |
279 | option (you cannot specify them in the | |
280 | .B \-S | |
281 | option). | |
282 | .TP | |
283 | .BR "\-A, \-\-protocol\-decoder\-annotations " <annotations> | |
284 | By default, only the stack's topmost protocol decoder's annotation output is | |
285 | shown. With this option another decoder's annotation can be selected for | |
286 | display, by specifying its ID: | |
287 | .sp | |
288 | $ | |
289 | .B "sigrok\-cli \-i <file.sr> \-P i2c,i2cfilter,edid -A i2c" | |
290 | .sp | |
291 | If a protocol decoder has multiple annotations, you can also specify | |
292 | which one of them to show by specifying its short description like this: | |
293 | .sp | |
294 | $ | |
295 | .B "sigrok\-cli \-i <file.sr> \-P i2c,i2cfilter,edid" | |
296 | .br | |
297 | .B " \-A i2c=data-read" | |
298 | .sp | |
299 | Select multiple annotations by separating them with a colon: | |
300 | .sp | |
301 | $ | |
302 | .B "sigrok\-cli \-i <file.sr> \-P i2c,i2cfilter,edid" | |
303 | .br | |
304 | .B " \-A i2c=data-read:data-write" | |
305 | .sp | |
306 | You can also select multiple protocol decoders, with an optional selected | |
307 | annotation each, by separating them with commas: | |
308 | .sp | |
309 | $ | |
310 | .B "sigrok\-cli \-i <file.sr> \-P i2c,i2cfilter,edid" | |
311 | .br | |
312 | .B " \-A i2c=data-read:data-write,edid" | |
313 | .TP | |
314 | .BR "\-M, \-\-protocol\-decoder\-meta " <pdname> | |
315 | When given, show protocol decoder meta output instead of annotations. | |
316 | The argument is the name of the decoder whose meta output to show. | |
317 | .sp | |
318 | $ | |
319 | .B "sigrok\-cli \-i <file.sr> \-M i2c" | |
320 | .sp | |
321 | Not every decoder generates meta output. | |
322 | .TP | |
323 | .BR "\-B, \-\-protocol\-decoder\-binary " <binaryspec> | |
324 | When given, decoder "raw" data of various kinds is written to stdout instead | |
325 | of annotations (this could be raw binary UART/SPI bytes, or WAV files, PCAP | |
326 | files, PNG files, or anything else; this is entirely dependent on the | |
327 | decoder and what kinds of binary output make sense for that decoder). | |
328 | .sp | |
329 | No other information is printed to stdout, so this is | |
330 | suitable for piping into other programs or saving to a file. | |
331 | .sp | |
332 | Protocol decoders that support binary output publish a list of binary | |
333 | classes, for example the UART decoder might have "TX" and "RX". To | |
334 | select TX for output, the argument to this option would be: | |
335 | .sp | |
336 | $ | |
337 | .B "sigrok\-cli \-i <file.sr> \-B uart=tx" | |
338 | .br | |
339 | .sp | |
340 | If only the protocol decoder is specified, without binary class, all classes | |
341 | are written to stdout: | |
342 | .sp | |
343 | $ | |
344 | .B "sigrok\-cli \-i <file.sr> \-B uart" | |
345 | .sp | |
346 | (this is only useful in rare cases, generally you would specify a certain | |
347 | binary class you're interested in) | |
348 | .sp | |
349 | Not every decoder generates binary output. | |
350 | .TP | |
351 | .BR "\-l, \-\-loglevel " <level> | |
352 | Set the libsigrok and libsigrokdecode loglevel. At the moment \fBsigrok-cli\fP | |
353 | doesn't support setting the two loglevels independently. The higher the | |
354 | number, the more debug output will be printed. Valid loglevels are: | |
355 | .sp | |
356 | \fB0\fP None | |
357 | .br | |
358 | \fB1\fP Error | |

367 | .TP | |
368 | .B "\-\-show" | |
369 | .br | |
370 | Show information about the selected option. For example, to see options for a | |
371 | connected fx2lafw device: | |
372 | .sp | |
373 | $ | |
374 | .B "sigrok\-cli \-\-driver fx2lafw \-\-show | |
375 | .sp | |
376 | In order to properly get device options for your hardware, some drivers might | |
377 | need a serial port specified: | |
378 | .sp | |
379 | $ | |
380 | .B "sigrok\-cli \-\-driver ols:conn=/dev/ttyACM0 \-\-show | |
381 | .sp | |

420 | You can optionally follow the number by \fBs\fP to specify the time to | |
421 | sample in seconds. | |
422 | .sp | |
423 | For example, | |

456 | .SH EXAMPLES | |
457 | In order to get exactly 100 samples from the connected fx2lafw-supported logic | |
458 | analyzer hardware, run the following command: | |
459 | .TP | |
460 | .B " sigrok\-cli \-\-driver fx2lafw \-\-samples 100" | |
461 | .TP | |
462 | If you want to sample data for 3 seconds (3000 ms), use: | |
463 | .TP | |
464 | .B " sigrok\-cli \-\-driver fx2lafw \-\-time 3000" | |
465 | .TP | |
466 | Alternatively, you can also use: | |
467 | .TP | |
468 | .B " sigrok\-cli \-\-driver fx2lafw \-\-time 3s" | |
