5 | This README contains various notes for users of libsigrok (or frontends | |
6 | that are based on libsigrok) about device- and/or driver-specific issues. | |
7 | ||
8 | ||
9 | Firmware | |
10 | -------- | |
11 | ||
12 | Some devices supported by libsigrok need a firmware to be uploaded every time | |
fadd0707 | 13 | the device is connected to the PC (usually via USB), before it can be used. |
c77ed446 | 14 | |
796f0e98 | 15 | The default locations where libsigrok expects the firmware files are: |
c77ed446 | 16 | |
1503d457 | 17 | $SIGROK_FIRMWARE_DIR (environment variable) |
796f0e98 | 18 | $HOME/.local/share/sigrok-firmware |
c77ed446 | 19 | $prefix/share/sigrok-firmware |
796f0e98 UH |
20 | /usr/local/share/sigrok-firmware |
21 | /usr/share/sigrok-firmware | |
c77ed446 UH |
22 | |
23 | ($prefix is usually /usr/local or /usr, depending on your ./configure options) | |

30 | Per-driver firmware requirements | |
31 | -------------------------------- | |
32 | ||
33 | The following drivers/devices require a firmware upload upon connection: | |
34 | ||
734bab71 GS |
35 | - asix-omega-rtm-cli: There is no native sigrok support for ASIX OMEGA |
36 | devices. But the vendor's RTM CLI application can be used in streaming | |
37 | mode, which transparently handles the device detection and firmware | |
38 | download. The firmware ships with the vendor application. See below | |
39 | for details how to make the vendor application available to the sigrok | |
40 | driver. | |
41 | ||
c77ed446 UH |
42 | - asix-sigma: The ASIX SIGMA and SIGMA2 require various firmware files, |
43 | depending on the settings used. These files are available from our | |
44 | 'sigrok-firmware' repository/project under a license which allows us | |
45 | to redistribute them. | |
46 | ||
599f9e1d UH |
47 | - dreamsourcelab-dslogic: The DreamSourceLab DSLogic/DSCope device series |
48 | requires various firmware files and FPGA bitstream files. | |

64 | from our 'sigrok-util' repository/project. | |
65 | ||
796f0e98 UH |
66 | - lecroy-logicstudio: The LeCroy LogicStudio requires FPGA bitstream files. |
67 | These can be extracted from the vendor's Windows software using a tool | |
68 | from our 'sigrok-util' repository/project. | |
69 | Additionally, it requires a Cypress FX2 firmware. This can be extracted | |
70 | from the vendor's Windows software using another tool. Details: | |

163 | Specifying serial ports | |
164 | ----------------------- | |
165 | ||
166 | Many devices supported by libsigrok use serial port based cables (real RS232 | |
f736691d GS |
167 | or USB-to-serial ones, CDC class) to connect to a PC. These serial cables are |
168 | supported by the libserialport library. Some vendors prefer to use HID chips | |
169 | instead of CDC chips in their serial cables. These cables can get supported | |
170 | by means of the hidapi library. Note that each chip type requires specific | |
07e42cb2 GS |
171 | support in the libsigrok library. Bluetooth connected devices may be supported |
172 | as well when they communicate by means of RFCOMM channels, or one of the | |
173 | implemented BLE notification/indication approaches, and one of the Bluetooth | |
174 | supporting platforms is used. | |
c77ed446 UH |
175 | |
176 | For all these devices, you need to specify the serial port they are connected | |
177 | to (e.g. using the 'conn' option in sigrok-cli). It is not possible to scan | |
178 | for such devices without specifying a serial port. | |
179 | ||
180 | Example: | |
181 | ||
182 | $ sigrok-cli --driver <somedriver>:conn=/dev/ttyUSB0 ... | |
f736691d | 183 | $ sigrok-cli --driver <somedriver>:conn=hid/cp2110 ... |
07e42cb2 | 184 | $ sigrok-cli --driver <somedriver>:conn=bt/rfcomm/01-23-45-67-89-ab ... |
c77ed446 | 185 | |
e2a391aa GS |
186 | Formal syntax for serial communication: |
187 | ||
188 | - COM ports (RS232, USB CDC): | |
189 | conn=<com-port> | |
190 | - USB HID cables: | |
191 | conn=hid[/<chip>] | |
192 | conn=hid[/<chip>]/usb=<bus>.<dev>[.<if>] | |
193 | conn=hid[/<chip>]/raw=<path> | |
194 | conn=hid[/<chip>]/sn=<serno> | |
d7df9dc7 | 195 | conn=hid[/<chip>]/iokit=<path> |
599f9e1d | 196 | chip can be: bu86x, ch9325, cp2110, victor |
e2a391aa GS |
197 | path may contain slashes |
198 | path and serno are "greedy" (span to the end of the spec) | |
199 | - Bluetooth Classic and Bluetooth Low Energy (BLE): | |
200 | conn=bt/<conn>/<addr> | |
201 | conn can be: rfcomm, ble122, nrf51, cc254x | |
202 | addr can be "dense" or separated, bt/cc254x/0123456789ab or | |
203 | bt/rfcomm/11-22-33-44-55-66 or bt/ble122/88:6b:12:34:56:78 | |
204 | (note that colons may not be available when the conn= spec is taken | |
205 | from a string that separates fields by colon, e.g. in the "--driver | |
206 | <name>:conn=<spec>" example, that is why the dense form and the use | |
207 | of dashes for separation are supported) | |
208 | ||
599f9e1d UH |
209 | Some of the drivers implement a default for the connection. Some of the |
210 | drivers can auto-detect USB connected devices. | |
c77ed446 | 211 | |
e2a391aa | 212 | Beyond strict serial communication over COM ports (discussed above), the |
ca25a3ee GS |
213 | conn= property can also address specific USB devices, as well as specify TCP |
214 | or VXI communication parameters. See these examples: | |
215 | ||
216 | $ sigrok-cli --driver <somedriver>:conn=<vid>.<pid> ... | |
217 | $ sigrok-cli --driver <somedriver>:conn=tcp-raw/<ipaddr>/<port> ... | |
218 | $ sigrok-cli --driver <somedriver>:conn=vxi/<ipaddr> ... | |
88c03eae | 219 | $ sigrok-cli --driver <somedriver>:conn=usbtmc/<bus>.<addr> ... |
ca25a3ee | 220 | |
e24ecabf GS |
221 | Individual device drivers _may_ implement additional semantics for the |
222 | conn= specification, which would not apply to other drivers, yet can be | |
223 | rather useful for a given type of device. | |
224 | ||
225 | $ sigrok-cli --driver <somedriver>:conn=sn=<serno> | |
226 | ||

228 | Specifying serial port parameters |
229 | --------------------------------- | |
48d3238e MH |
230 | |
231 | Every serial device's driver has default serial port parameters like baud | |
232 | rate, number of data bits, stop bits and handshake status. If a device requires | |
233 | different parameters, pass them as option "serialcomm" with the driver name. | |
e311f770 | 234 | See libsigrok docs for the function serial_set_paramstr() for complete specs. |
48d3238e MH |
235 | |
236 | Example: | |
237 | ||
238 | $ sigrok-cli --driver <somedriver>:conn=<someconn>:serialcomm=9600/7n1/dtr=1 | |
239 | ||
240 | ||
c77ed446 UH |
241 | Permissions of serial port based devices |
242 | ---------------------------------------- | |
243 | ||
244 | When using devices supported by libsigrok that use serial port based cables | |
245 | (real RS232 or USB-to-serial ones) to connect to a PC, you need to ensure | |
246 | that the user running the libsigrok frontend has (read/write) permissions to | |
247 | access the serial port device (e.g. /dev/ttyS0, /dev/ttyUSB0, and so on). | |
248 | ||
249 | You can use 'chmod' to apply permissions as you see fit, and/or 'chown' to | |
250 | change the owner of the serial port device to a certain user or group. | |
251 | ||
252 | For USB-to-serial based devices, we recommended using our udev rules file | |
253 | (see below for details). | |
254 | ||
255 | ||

256 | Permissions for USB devices (udev rules files) |
257 | ---------------------------------------------- | |
c77ed446 UH |
258 | |
259 | When using USB-based devices supported by libsigrok, the user running the | |
260 | libsigrok frontend (e.g. sigrok-cli) has to have (read/write) permissions | |
261 | for the respective USB device. | |
262 | ||
75696630 SB |
263 | On Linux, this is accomplished using udev rules. libsigrok ships a rules |
264 | file containing all supported devices which can be detected reliably | |
265 | (generic USB-to-serial converters are omitted, as these are used for a wide | |
266 | range of devices, e.g. GPS receivers, which are not handled by libsigrok). | |
c77ed446 | 267 | |
75696630 SB |
268 | The file is available in contrib/60-libsigrok.rules. This file just contains |
269 | the list of devices and flags these devices with ID_SIGROK="1". Access is | |
270 | granted by the 61-libsigrok-plugdev.rules or 61-libsigrok-uaccess.rules files, | |
271 | allowing access to members of the plugdev group or to currently logged in | |
272 | users, respectively. | |
c77ed446 UH |
273 | |
274 | When using a libsigrok package from your favorite Linux distribution, the | |
75696630 SB |
275 | files should already be installed in /usr/lib/udev/rules.d/, i.e. |
276 | 60-libsigrok.rules and one of the access granting rules files. Use of | |
277 | 61-libsigrok-uaccess.rules is encouraged on systemd distributions. | |
278 | ||
279 | The access policy can be locally overridden by placing appropriate rules in | |
280 | /etc/udev/rules.d/, disabling or ammending the default policy. See the | |
281 | udev documentation, e.g. man 7 udev, for details. | |
c77ed446 UH |
282 | |
283 | If you're building from source, you need to copy the file to the place | |
75696630 SB |
284 | where udev will read these rules. Local rules should go to /etc/udev/rules.d. |
285 | Keep the file naming, otherwise interaction between the libsigrok rules and | |
286 | rules shipped by the system will be broken. | |
c77ed446 | 287 | |
75696630 | 288 | Please consult the udev docs for details. |

291 | Non-default drivers for commodity chips |
292 | --------------------------------------- | |
293 | ||
294 | Some vendors include common USB chips in their products yet assign device | |
295 | specific VID:PID pairs. Which results in the necessity for extra steps | |
296 | before the serial port can be used: | |
297 | ||
298 | - GW Instek VCP, found in GDM-8000 and probably other meters: Install the | |
299 | vendors Windows driver to get access to a COM port. Or force the driver | |
300 | assignment on Linux: | |
301 | # modprobe cp210x | |
302 | # echo 2184 0030 > /sys/bus/usb-serial/drivers/cp210x/new_id | |
303 | ||
304 | ||
c77ed446 UH |
305 | Cypress FX2 based devices |
306 | ------------------------- | |
307 | ||
308 | Devices using the Cypress FX2(LP) chip without any specific USB VID/PID will | |
309 | be enumerated with VID/PID 04b4:8613 (the default for "unconfigured FX2"). | |
310 | These are usually "FX2 eval boards" (that can also be used as LAs, though). | |
311 | ||
312 | On Linux, the 'usbtest' driver will usually grab such devices, and they will | |
313 | thus not be usable by libsigrok (and frontends). | |
314 | ||
315 | You can fix this by running 'rmmod usbtest' as root before using the device. | |
316 | ||
317 | ||
318 | UNI-T DMM (and rebranded models) cables | |
319 | --------------------------------------- | |
320 | ||
321 | UNI-T multimeters (and rebranded devices, e.g. some Voltcraft models) can | |
322 | ship with different PC connectivity cables: | |
323 | ||
de805ae5 | 324 | - UT-D02 (RS232 cable) |
c77ed446 UH |
325 | - UT-D04 (USB/HID cable with Hoitek HE2325U chip, USB VID/PID 04fa:2490) |
326 | - UT-D04 (USB/HID cable with WCH CH9325 chip, USB VID/PID 1a86:e008) | |
07e42cb2 | 327 | - UT-D07 (Bluetooth adapter, ISSC BL79 BLETR chip) |
f736691d | 328 | - UT-D09 (USB/HID cable with SiL CP2110 chip, USB VID/PID 10c4:ea80) |
c77ed446 UH |
329 | |
330 | The above cables are all physically compatible (same IR connector shape) | |
331 | with all/most currently known UNI-T multimeters. For example, you can | |
332 | use either of the UT-D04 USB/HID cables or the UT-D02 RS232 cable with | |
333 | the UNI-T UT61D multimeter. | |
334 | ||
335 | When using the UT-D02 RS232 cable with any of the supported UNI-T DMMs, | |
336 | you have to use the respective driver with a '-ser' drivername suffix | |
337 | (internally all of these models are handled by the 'serial-dmm' driver). | |
338 | ||
339 | You also need to specify the serial port via the 'conn' option, e.g. | |
340 | /dev/ttyUSB0 (attached via a USB-to-serial cable) or /dev/ttyS0 (actual | |
341 | RS232 port) on Linux (see above). | |
342 | ||
343 | Finally, the user running the frontend (e.g. sigrok-cli) also needs | |
344 | permissions to access the respective serial port (see above). | |
345 | ||
346 | Examples (sigrok-cli): | |
347 | ||
348 | $ sigrok-cli --driver uni-t-ut61e-ser:conn=/dev/ttyUSB0 ... | |
349 | $ sigrok-cli --driver voltcraft-vc820-ser:conn=/dev/ttyS0 ... | |
350 | ||
351 | When using any of the UT-D04 USB/HID cables you have to use the respective | |
352 | driver _without_ the '-ser' drivername suffix (internally all of these models | |
353 | are handled by the 'uni-t-dmm' driver). | |
354 | ||
9b2f03bb UH |
355 | You also need to specify the USB vendor/device IDs of the cable. |
356 | Autodetection is not possible here, since various other products use the | |
357 | USB VID/PID of those cables too, and there is no way to distinguish them. | |
358 | ||
c77ed446 UH |
359 | Since the UT-D04 cables are USB based (but don't use a USB-to-serial chip) |
360 | there is no need to specify a serial port via 'conn', of course. | |
361 | However, the user running the frontend does also need to have permissions | |
362 | to access the respective USB device (see above). | |
363 | ||
364 | Examples (sigrok-cli): | |
365 | ||
9b2f03bb UH |
366 | $ sigrok-cli --driver uni-t-ut61e:conn=1a86.e008 ... |
367 | $ sigrok-cli --driver voltcraft-vc820:conn=04fa.2490 ... | |

373 | The UNI-T UT-D04 cable with Hoitek HE2325U (or WCH CH9325) chip seems to have | |
8d3764aa | 374 | a very specific problem on Linux. Apparently it requires to be put into |
c77ed446 UH |
375 | suspend (and woken up again) before it is usable. This seems to be a |
376 | Linux-only issue, Windows is not affected by this since apparently the | |
377 | Windows kernel does this for every USB device, always. | |
378 | ||
379 | Thus, if you want to use any of the UNI-T DMMs with this specific cable, | |
380 | you'll have to run the following script (as root) once, every time you attach | |
381 | the cable via USB. The script was written by Ralf Burger. | |

393 | Enabling multimeter / data logger measurement output |
394 | ---------------------------------------------------- | |
395 | ||
396 | Some multimeters or data loggers will not start outputting measurement data | |
397 | unless a certain action has been performed by the user beforehand. This is | |
398 | usually mentioned in the vendor manual of the respective device, but here's | |
399 | a short list for convenience: | |

448 | ASIX OMEGA in RTM CLI mode |
449 | -------------------------- | |
450 | ||
451 | The asix-sigma driver can detect the Omega devices' presence, but does | |
452 | not support their protocol and emits a diagnostics message. The firmware | |
453 | image is not available for distribution, and information on the protocol | |
454 | is not available. That's why native support is in some distant future. | |
455 | Yet basic operation of Omega devices is available by using the vendor's | |
456 | command line application for real time mode (RTM CLI). | |
457 | ||
458 | The vendor application targets Windows (on x86), but also executes on | |
459 | Linux when 32bit libraries for FTDI communication are provided. The | |
460 | user manual discusses the installation. The sigrok asix-omega-rtm-cli | |
461 | driver uses the vendor provided omegartmcli.exe binary to configure the | |
462 | device for streaming, and to acquire sample data. | |
463 | ||
464 | Either make an "omegartmcli" executable available in PATH. This can be | |
465 | the vendor's executable or some wrapper around it or a symlink to it. | |
466 | Or specify the executable's location in the OMEGARTMCLI environment | |
467 | variable. The sigrok driver accepts an optional serial number (six or | |
468 | eight hex digits) to select one out of several connected devices. | |
469 | ||
470 | (optional) | |
471 | $ export "OMEGARTMCLI=$HOME/.wine/drive_c/progx86/ASIX/SIGMA/omegartmcli.exe" | |
472 | ||
473 | (optional) | |
474 | $ OMEGASN=":conn=sn=a6030123" | |
475 | ||
476 | (example use) | |
477 | $ sigrok-cli -d asix-omega-rtm-cli${OMEGASN} --show | |
478 | $ sigrok-cli -d asix-omega-rtm-cli${OMEGASN} -o capture.sr --time 10s | |
479 | $ sigrok-cli -d asix-omega-rtm-cli${OMEGASN} -o capture.sr --samples 100m | |
480 | $ pulseview -d asix-omega-rtm-cli${OMEGASN} | |
481 | ||
482 | The RTM mode of operation samples 16 channels at a fixed rate of 200MHz. | |
483 | Hardware triggers are not available in this mode. Glib should handle | |
484 | platform specific details of external process execution, but the driver | |
485 | was only tested on Linux so far. Acquisition start in sigrok applications | |
486 | may take some time before sample data becomes available (roughly one | |
487 | second here on a slow machine). This is an implementation detail of the | |
488 | RTM CLI approach including execution under wine. | |
489 | ||
490 | The reliability of that setup in the presence of fast changing input | |
491 | signals is yet to get determined. It's assumed that slow input signals | |
492 | are operational. It's essential that the _average_ rate of changes in | |
493 | the input signal in combination with the hardware compression are such | |
494 | that the FTDI FIFO can communicate all involved data via USB2.0 to the | |
495 | application. Intermediate bursts of rapid changes shall not be an issue | |
496 | given the Omega devices' deep memory which RTM uses for buffering. | |
497 | ||
498 | Native support for the Asix Omega devices depends on the availability of | |
499 | a protocol description and use of the protocol depends on the firmware's | |
500 | availability at the user's site. Which then would allow to capture to | |
501 | DRAM at high rates without the communication bottleneck, before the data | |
502 | gets communicated to the PC after the acquisition has completed. Compare | |
c5dd6c4f | 503 | the native sigrok support for Asix Sigma. |

506 | ChronoVu LA8/LA16 USB VID/PIDs |
507 | ------------------------------ | |
c77ed446 | 508 | |
7b356712 UH |
509 | The ChronoVu LA8/LA16 logic analyzer is available in two revisions. Previously, |
510 | the device shipped with a USB VID/PID of 0403:6001, which is the standard ID | |
c77ed446 UH |
511 | for FTDI FT232 USB chips. |
512 | ||
7b356712 | 513 | Since this made it hard to distinguish the LA8/LA16 from any other device |
c77ed446 | 514 | with this FTDI chip connected to the PC, the vendor later shipped the |
7b356712 | 515 | device with a USB VID/PID of 0403:8867. |
c77ed446 | 516 | |
7b356712 UH |
517 | The 'chronovu-la' driver in libsigrok supports both VID/PID pairs and |
518 | automatically finds devices with either VID/PID pair. | |

521 | OLS | |
522 | --- | |
523 | ||
e311f770 UH |
524 | The Dangerous Prototypes Openbench Logic Sniffer (OLS) logic analyzer |
525 | driver in libsigrok assumes a somewhat recent firmware has been flashed onto | |
526 | the OLS (it doesn't need a firmware upload every time it's attached via USB, | |
527 | since the firmware is stored in the device permanently). | |
c77ed446 UH |
528 | |
529 | The most recent firmware version that is tested is 3.07. | |
530 | ||
531 | If you use any older firmware and your OLS is not found or is not working | |
532 | properly, please upgrade to at least this firmware version. Check the | |
533 | Dangerous Prototypes wiki for firmware upgrade instructions: | |
534 | ||
535 | http://dangerousprototypes.com/docs/Logic_Sniffer_upgrade_procedure | |
536 | ||
537 | Also, you need to specify a serial port for the OLS in the frontends, e.g. | |
538 | using the 'conn' option in sigrok-cli, and you also need to have the | |
539 | permissions to access the serial port (see above). | |
540 | ||
541 | Example: | |
542 | ||
543 | $ sigrok-cli --driver ols:conn=/dev/ttyACM0 ... | |

546 | JTAGulator |
547 | ---------- | |
548 | ||
549 | The Grand Idea Studio JTAGulator also implements the SUMP protocol and | |
550 | thus is covered by the OLS driver. See the vendor's wiki on details how | |
551 | to enable the Logic Analyzer mode of operation. | |

556 | Mooshimeter |
557 | ----------- | |
558 | ||
559 | The Mooshim Engineering Mooshimeter is controlled via Bluetooth Low Energy | |
560 | (sometimes called Bluetooth 4.0), as such it requires a supported Bluetooth | |
561 | interface available. The 'conn' option is required and must contain the | |
562 | Bluetooth MAC address of the meter. | |
563 | ||
564 | Example: | |
565 | ||
566 | $ sigrok-cli --driver mooshimeter-dmm:conn=12-34-56-78-9A-BC ... | |
567 | ||
568 | Since the Mooshimeter has no physical interface on the meter itself, the | |
569 | channel configuration is set with the 'channel_config' option. The format | |
570 | of this option is 'CH1,CH2' where each channel configuration has the form | |
571 | 'MODE:RANGE:ANALYSIS', with later parts being optional. In addition for | |
572 | CLI compatibility, the ',' in the channels can also be a '/' and the ':' in | |
573 | the individual configuration can be a ';'. | |
574 | ||
575 | Available channel 1 modes: | |
576 | ||
577 | - Current, A: Current in amps | |
578 | - Temperature, T, K: Internal meter temperature in Kelvin | |
579 | - Resistance, Ohm, W: Resistance in ohms | |
580 | - Diode, D: Diode voltage | |
581 | - Aux, LV: Auxiliary (W input) low voltage sensor (1.2V max) | |
582 | ||
583 | Available channel 2 modes: | |
584 | ||
585 | - Voltage, V: Voltage | |
586 | - Temperature, T, K: Internal meter temperature in Kelvin | |
587 | - Resistance, Ohm, W: Resistance in ohms | |
588 | - Diode, D: Diode voltage | |
589 | - Aux, LV: Auxiliary (W input) low voltage sensor (1.2V max) | |
590 | ||
591 | Only one channel can use the shared inputs at a time (e.g. if CH1 is measuring | |
592 | resistance, CH2 cannot measure low voltage). Temperature is excepted from | |
593 | this, so the meter can measure internal temperature and low voltage at the | |
594 | same time. | |
595 | ||
596 | Additionally, the meter can calculate the real power of both channels. This | |
597 | generally only makes sense when CH1 is set to current and CH2 is set to a | |
598 | voltage and so it is disabled by default. It must be enabled by enabling the | |
599 | 'P' channel (the third channel). | |
600 | ||
601 | The range of the channel specification sets the maximum input for that channel | |
602 | and is rounded up to the next value the meter itself supports. For example, | |
603 | specifying 50 for the voltage will result in the actual maximum of 60. | |
604 | Specifying 61 would result in 600. If omitted, sigrok will perform | |
605 | auto-ranging of the channel by selecting the next greater value than the | |
606 | latest maximum. | |
607 | ||
608 | The analysis option sets how the meter reports its internal sampling buffer | |
609 | to sigrok: | |
610 | ||
611 | - Mean, DC: The default is a simple arithmetic mean of the sample buffer | |
612 | - RMS, AC: The root mean square of the sample buffer | |
613 | - Buf, Buffer, Samples: Report the entire sample buffer to sigrok. This | |
614 | results in packets that contain all the samples in the buffer instead | |
615 | of a single output value. | |
616 | ||
617 | The size of the sample buffer is set with the 'avg_samples' option, while | |
618 | the sampling rate is set with the 'samplerate' option. So the update rate | |
619 | is avg_samples/samplerate. Both are rounded up to the next supported value | |
620 | by the meter. | |
621 | ||
622 | Example: | |
623 | ||
624 | $ sigrok-cli -c channel_config="Aux;0.1/T" --driver mooshimeter-dmm... | |
625 | $ sigrok-cli -c channel_config="A;;AC/V;;AC" --driver mooshimeter-dmm... |
