6 | .SH "DESCRIPTION" |
7 | .B sigrok\-cli | |
8 | is a cross-platform command line utility for the | |
9 | .B sigrok | |
10 | logic analyzer software. | |
11 | .PP | |
12 | The command-line frontend for sigrok cannot display graphical output, but is | |
13 | still sufficient to run through the whole process of hardware initialization, | |
85f2ddbb | 14 | acquisition, protocol decoding and saving the session. |
43e5747a UH |
15 | .PP |
16 | It is useful for running on remote or embedded systems, netbooks, PDAs, | |
17 | and for various other use-cases. It can display samples on standard output or | |
18 | save them in various file formats. | |
19 | .SH "OPTIONS" | |
20 | .TP | |
43e5747a UH |
21 | .B "\-h, \-\-help" |
22 | Show a help text and exit. | |
23 | .TP | |
7949dca0 UH |
24 | .B "\-V, \-\-version" |
25 | Show | |
26 | .B sigrok-cli | |
27 | version, and information about supported hardware drivers, input file | |
28 | formats, output file formats, and protocol decoders. | |
29 | .TP | |
85f2ddbb UH |
30 | .BR "\-l, \-\-loglevel " <level> |
31 | Set the libsigrok and libsigrokdecode loglevel. At the moment | |
32 | .B sigrok-cli | |
33 | doesn't support setting the two loglevels independently. The higher the | |
34 | number, the more debug output will be printed. Valid loglevels are | |
35 | .BR 0 " (NONE)," | |
36 | .BR 1 " (ERR)," | |
37 | .BR 2 " (WARN)," | |
38 | .BR 3 " (INFO)," | |
39 | .BR 4 " (DBG), and" | |
40 | .BR 5 " (SPEW)." | |
41 | .TP | |
43e5747a | 42 | .B "\-D, \-\-list\-devices" |
7949dca0 UH |
43 | List all logic analyzer devices found on the system. This actively scans for |
44 | devices (USB, serial port, and others). | |
43e5747a | 45 | .TP |
1b4b6a7c UH |
46 | .BR "\-d, \-\-device " <device> |
47 | The device to use for acquisition. It can be specified by ID as reported by | |
48 | .BR "\-\-list\-devices" , | |
49 | or by the name of the driver as reported by | |
50 | .BR \-\-version . | |
51 | .sp | |
52 | A device can optionally be followed by a colon-separated list of device | |
53 | options, where each option takes the form | |
54 | .BR key=value . | |
55 | For example, to set the samplerate on the first device you might specify | |
56 | .sp | |
57 | .RB " $ " "sigrok\-cli \-d 0:samplerate=1m" | |
58 | .sp | |
59 | Samplerate is an option common to most devices. The argument specifies the | |
60 | samplerate in Hz. You can also specify the samplerate in kHz, MHz or GHz. | |
61 | The following are all equivalent: | |
62 | .sp | |
63 | .RB " $ " "sigrok\-cli \-\-samples 100 \-d 0:samplerate=1000000" | |
64 | .sp | |
65 | .RB " $ " "sigrok\-cli \-\-samples 100 \-d 0:samplerate=1m" | |
66 | .sp | |
67 | .RB " $ " "sigrok\-cli \-\-samples 100 \-d ""0:samplerate=1 MHz"" | |
68 | .TP | |
43e5747a | 69 | .BR "\-i, \-\-input\-file " <filename> |
7949dca0 | 70 | Load input from a file instead of a hardware device. If the |
43e5747a UH |
71 | .B \-\-input\-format |
72 | option is not supplied, sigrok-cli attempts to autodetect the file format of | |
73 | the input file. | |
74 | .TP | |
75 | .BR "\-I, \-\-input\-format " <format> | |
76 | When loading an input file, assume it's in the specified format. If this | |
77 | option is not supplied (in addition to | |
78 | .BR \-\-input\-file ), | |
943d0c08 TŠ |
79 | sigrok-cli attempts to autodetect the file format of the input file. Use the |
80 | .B \-V | |
81 | option to see a list of available input formats. The format name may | |
82 | optionally be followed by a colon-separated list of options, where each | |
83 | option takes the form | |
84 | .BR "key=value" . | |
43e5747a UH |
85 | .TP |
86 | .BR "\-o, \-\-output\-file " <filename> | |
87 | Save output to a file instead of writing it to stdout. The default format | |
88 | used when saving is the sigrok session file format. This can be changed with | |
89 | the | |
76ae913d | 90 | .B \-\-output\-format |
7949dca0 UH |
91 | option. |
92 | .TP | |
93 | .BR "\-O, \-\-output\-format " <formatname> | |
94 | Set the output format to use. Use the | |
95 | .B \-V | |
96 | option to see a list of available output formats. The format name may | |
97 | optionally be followed by a colon-separated list of options, where each | |
98 | option takes the form | |
99 | .BR "key=value" . | |
100 | .sp | |
101 | Supported formats currently include | |
102 | .BR bits , | |
103 | .BR hex , | |
104 | .BR ascii , | |
105 | .BR binary , | |
106 | .BR vcd , | |

111 | .sp |
112 | The | |
113 | .B bits | |
114 | or | |
115 | .B hex | |
116 | 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 | |
117 | .B hex:width=128 | |
118 | will display 128 bits per line, in hexadecimal: | |
119 | .sp | |
120 | 1:ffff ffff ffff ffff ffff ffff ffff ffff | |
121 | 2:ff00 ff00 ff00 ff00 ff00 ff00 ff00 ff00 | |
122 | .sp | |
123 | The lines always start with the probe number (or name, if defined), followed by a colon. If no format is specified, it defaults to | |
124 | .BR bits:width=64 , | |
125 | like this: | |
126 | .sp | |
127 | 1:11111111 11111111 11111111 11111111 [...] | |
128 | 2:11111111 00000000 11111111 00000000 [...] | |
43e5747a | 129 | .TP |
43e5747a UH |
130 | .BR "\-p, \-\-probes " <probelist> |
131 | A comma-separated list of probes to be used in the session. | |
132 | .sp | |
133 | The default is to use all the probes available on a device. You can name | |
134 | a probe like this: | |
135 | .BR "1=CLK" . | |
136 | A range of probes can also be given, in the form | |
137 | .BR "1\-5" . | |
138 | .sp | |
139 | Example: | |
140 | .sp | |
141 | $ | |
142 | .B "sigrok\-cli \-\-samples 100 \-\-probes 1=CLK,2\-4,7" | |
143 | .br | |
144 | CLK:11111111 11111111 11111111 11111111 [...] | |
145 | 2:11111111 11111111 11111111 11111111 [...] | |
146 | 3:11111111 11111111 11111111 11111111 [...] | |
147 | 4:11111111 11111111 11111111 11111111 [...] | |
148 | 7:11111111 11111111 11111111 11111111 [...] | |
149 | .sp | |
150 | The comma-separated list is processed from left to right, i.e. items farther | |
151 | to the right override previous items. For example | |
152 | .B "1=CS,1=MISO" | |
153 | will set the name of probe 1 to | |
154 | .BR "MISO" . | |
155 | .sp | |
156 | Also, while | |
157 | .B "5=MOSI,6=MISO" | |
158 | will only select probes 5 and 6, and set their names to MISO and MOSI, the | |
159 | command line | |
160 | .B "5=MOSI,6=MISO,1\-8" | |
161 | will select probes 1\-8 (including 5 and 6, of course), but the names specified | |
162 | for probes 5 and 6 will be reset to the defaults by the | |
163 | .B "1\-8" | |
164 | probe selection. | |
165 | .TP | |
166 | .BR "\-t, \-\-triggers " <triggerlist> | |
167 | A comma-separated list of triggers to use, of the form | |
168 | .BR "<probe>=<trigger>" . | |
169 | You can use the name or number of the probe, and the trigger itself is a | |
170 | series of characters: | |
171 | .sp | |
172 | .BR "0 or 1" : | |
173 | A low or high value on the pin. | |
174 | .br | |
175 | .BR "r or f" : | |
176 | A rising or falling value on the pin. An | |
177 | .B r | |
178 | effectively corresponds to | |
179 | .BR 01 . | |
180 | .br | |
181 | .BR "c" : | |
85f2ddbb | 182 | Any kind of change on a pin (either a rising or a falling edge). |
43e5747a UH |
183 | .sp |
184 | Not every device supports all of these trigger types. Use the | |
185 | .B "\-d <device>" | |
186 | argument (with no other arguments) to see which triggers your device supports. | |
187 | .TP | |
188 | .BR "\-w, \-\-wait-trigger" | |
189 | Don't output any sample data (even if it's actually received from the logic | |
190 | analyzer) before the trigger condition is met. In other words, do not output | |
191 | any pre-trigger data. This option is useful if you don't care about the data | |
192 | that came before the trigger (but the logic analyzer hardware delivers this | |
193 | data to sigrok nonetheless). | |
194 | .TP | |
85f2ddbb UH |
195 | .BR "\-a, \-\-protocol\-decoders " <list> |
196 | This option allows the user to specify a comma-separated list of protocol | |
197 | decoders to be used in this session. The decoders are specified by their | |
198 | ID, as shown in the | |
199 | .B \-\-version | |
200 | output. | |
201 | .sp | |
202 | Example: | |
203 | .sp | |
204 | $ | |
205 | .B "sigrok\-cli \-i <file.sr> \-a i2c" | |
206 | .sp | |
207 | Each protocol decoder can optionally be followed by a colon-separated list | |
208 | of options, where each option takes the form | |
209 | .BR "key=value" . | |
210 | .sp | |
211 | Example: | |
212 | .sp | |
213 | $ | |
214 | .B "sigrok\-cli \-i <file.sr> \-a uart:baudrate=115200:parity=odd" | |
215 | .sp | |
216 | The list of supported options depends entirely on the protocol decoder. Every | |
217 | protocol decoder has different options it supports. | |
218 | .sp | |
219 | Any "options" specified for a protocol decoder which are not actually | |
220 | supported options, will be interpreted as being probe name/number assignments. | |
221 | .sp | |
222 | Example: | |
223 | .sp | |
224 | $ | |
225 | .B "sigrok\-cli \-i <file.sr>" | |
226 | .br | |
227 | .B " \-a spi:wordsize=9:miso=1:mosi=5:sck=3:cs=0" | |
228 | .sp | |
229 | In this example, | |
230 | .B wordsize | |
231 | is an option supported by the | |
232 | .B spi | |
233 | protocol decoder. Additionally, the user tells sigrok to decode the SPI | |
234 | protocol using probe 1 as MISO signal for SPI, probe 5 as MOSI, probe 3 | |
235 | as SCK, and probe 0 as CS# signal. | |
236 | .TP | |
237 | .BR "\-s, \-\-protocol\-decoder\-stack " <stack> | |
238 | This option allows the user to specify a protocol decoder stack, i.e. | |
239 | the way in which one protocol decoder's output gets piped into another | |
7fb87027 | 240 | protocol decoder. If not specified, the stack will be set up in the same |
1a0be0e3 UH |
241 | order in which the protocol decoders were given with the |
242 | .B \-\-protocol-decoders | |
7fb87027 | 243 | option. |
85f2ddbb UH |
244 | .sp |
245 | The decoders are specified by their ID, as shown in the | |
246 | .B \-\-version | |
247 | output. In addition to the | |
248 | .B \-s | |
249 | option, all protocol decoders that are used in a stack, must also be specified | |
250 | (together with their options, if any) using the | |
251 | .B \-a | |
252 | parameter. | |
253 | .sp | |
254 | Example: | |
255 | .sp | |
256 | $ | |
2d4077a7 | 257 | .B "sigrok\-cli \-i <file.sr> \-a i2c:sda=4:scl=7,rtc8564" |
85f2ddbb UH |
258 | .br |
259 | .B " \-s i2c,rtc8564" | |
260 | .sp | |
261 | In this example, the | |
262 | .B \-s | |
263 | option specifies that the output of the | |
264 | .BR i2c " decoder" | |
265 | is piped into the | |
266 | .BR rtc8564 " decoder," | |
267 | i.e., the | |
268 | .BR rtc8564 " decoder" | |
269 | is stacked on top of the | |
270 | .BR i2c " decoder." | |
271 | .sp | |
272 | The respective protocol decoder options and probe name/number assignments | |
273 | must be given using the | |
274 | .B \-a | |
275 | option (you cannot specify them in the | |
276 | .B \-s | |
277 | option). | |
278 | .TP | |
b6bd032d | 279 | .BR "\-A, \-\-protocol\-decoder\-annotations " <annotations> |
7fb87027 BV |
280 | By default, only the stack's topmost protocol decoder's annotation output is |
281 | shown. With this option another decoder's annotation can be selected for | |
1a0be0e3 | 282 | display, by specifying its ID: |
7fb87027 BV |
283 | .sp |
284 | $ | |
b6bd032d | 285 | .B "sigrok\-cli \-i <file.sr> \-a i2c,i2cfilter,edid -A i2c" |
7fb87027 BV |
286 | .sp |
287 | If a protocol decoder has multiple annotation formats, you can also specify | |
288 | which of them to show by specifying its short description like this: | |
289 | .sp | |
290 | $ | |
291 | .B "sigrok\-cli \-i <file.sr> \-a i2c,i2cfilter,edid" | |
292 | .br | |
b6bd032d | 293 | .B " \-A i2c=rawhex" |
7fb87027 BV |
294 | .sp |
295 | You can also select multiple protocol decoders, with an optional selected | |
296 | annotation format each, by separating them with commas: | |
297 | .sp | |
298 | $ | |
299 | .B "sigrok\-cli \-i <file.sr> \-a i2c,i2cfilter,edid" | |

322 | .TP | |
323 | .B " sigrok\-cli \-\-samples 100" | |
324 | .TP | |
325 | If you want to sample data for 3 seconds, use: | |
326 | .TP | |
327 | .B " sigrok\-cli \-\-time 3000" | |
