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 UH |
14 | |
15 | The default location where libsigrok expects the firmware files is: | |
16 | ||
17 | $prefix/share/sigrok-firmware | |
18 | ||
19 | ($prefix is usually /usr/local or /usr, depending on your ./configure options) | |
20 | ||
21 | For further information see the section below and also: | |

24 | ||
25 | ||
26 | Per-driver firmware requirements | |
27 | -------------------------------- | |
28 | ||
29 | The following drivers/devices require a firmware upload upon connection: | |
30 | ||
31 | - asix-sigma: The ASIX SIGMA and SIGMA2 require various firmware files, | |
32 | depending on the settings used. These files are available from our | |
33 | 'sigrok-firmware' repository/project under a license which allows us | |
34 | to redistribute them. | |
35 | ||
36 | - fx2lafw: Logic analyzers based on the Cypress FX2(LP) chip need the | |
37 | firmware files from the 'sigrok-firmware-fx2lafw' repository/project. | |
e311f770 | 38 | The firmware is written from scratch and licensed under the GNU GPLv2+. |
c77ed446 UH |
39 | |
40 | - hantek-dso: The Hantek DSO-2090 (and other supported models of the same | |
41 | series of Hantek PC oscilloscopes) need firmware files. | |
42 | These can be extracted from the vendor's Windows drivers using a tool | |
43 | from our 'sigrok-util' repository/project. | |
44 | ||
1b142b78 UH |
45 | - saleae-logic16: The Saleae Logic16 needs a firmware file for the |
46 | Cypress FX2 chip in the device, as well as two FPGA bitstream files. | |
47 | These can be extracted from the vendor's Linux application using a tool | |
48 | from our 'sigrok-util' repository/project. | |
49 | ||
e311f770 UH |
50 | - sysclk-lwla: The Sysclk LWLA1034 requires various bitstream files. |
51 | These files are available from our 'sigrok-firmware' repository/project | |
52 | under a license which allows us to redistribute them. | |

90 | Specifying serial ports | |
91 | ----------------------- | |
92 | ||
93 | Many devices supported by libsigrok use serial port based cables (real RS232 | |
94 | or USB-to-serial ones) to connect to a PC. | |
95 | ||
96 | For all these devices, you need to specify the serial port they are connected | |
97 | to (e.g. using the 'conn' option in sigrok-cli). It is not possible to scan | |
98 | for such devices without specifying a serial port. | |
99 | ||
100 | Example: | |
101 | ||
102 | $ sigrok-cli --driver <somedriver>:conn=/dev/ttyUSB0 ... | |
103 | ||

149 | Specifiying serial port parameters |
150 | ---------------------------------- | |
151 | ||
152 | Every serial device's driver has default serial port parameters like baud | |
153 | rate, number of data bits, stop bits and handshake status. If a device requires | |
154 | different parameters, pass them as option "serialcomm" with the driver name. | |
e311f770 | 155 | See libsigrok docs for the function serial_set_paramstr() for complete specs. |
48d3238e MH |
156 | |
157 | Example: | |
158 | ||
159 | $ sigrok-cli --driver <somedriver>:conn=<someconn>:serialcomm=9600/7n1/dtr=1 | |
160 | ||
161 | ||
c77ed446 UH |
162 | Permissions of serial port based devices |
163 | ---------------------------------------- | |
164 | ||
165 | When using devices supported by libsigrok that use serial port based cables | |
166 | (real RS232 or USB-to-serial ones) to connect to a PC, you need to ensure | |
167 | that the user running the libsigrok frontend has (read/write) permissions to | |
168 | access the serial port device (e.g. /dev/ttyS0, /dev/ttyUSB0, and so on). | |
169 | ||
170 | You can use 'chmod' to apply permissions as you see fit, and/or 'chown' to | |
171 | change the owner of the serial port device to a certain user or group. | |
172 | ||
173 | For USB-to-serial based devices, we recommended using our udev rules file | |
174 | (see below for details). | |
175 | ||
176 | ||
177 | Permissions for USB devices (udev rules file) | |
178 | --------------------------------------------- | |
179 | ||
180 | When using USB-based devices supported by libsigrok, the user running the | |
181 | libsigrok frontend (e.g. sigrok-cli) has to have (read/write) permissions | |
182 | for the respective USB device. | |
183 | ||
184 | On Linux, this is accomplished using either 'chmod' (not recommended) or | |
185 | using the udev rules file shipped with libsigrok (recommended). | |
186 | ||
187 | The file is available in contrib/z60_libsigrok.rules. It contains entries | |
188 | for all libsigrok-supported (USB-based) devices and changes their group | |
189 | to 'plugdev' and the permissions to '664'. | |
190 | ||
191 | When using a libsigrok package from your favorite Linux distribution, the | |
192 | packager will have already taken care of properly installing the udev file | |
193 | in the correct (distro-specific) place, and you don't have to do anything. | |
194 | The packager might also have adapted 'plugdev' and '664' as needed. | |
195 | ||
196 | If you're building from source, you need to copy the file to the place | |
197 | where your distro expects such files. This is beyond the scope of this README, | |
198 | but generally the location could be e.g. /etc/udev/rules.d, or maybe | |
199 | /lib/udev/rules.d, or something else. Afterwards you might have to restart | |
200 | udev, e.g. via '/etc/init.d/udev restart' or similar, and you'll have to | |
201 | re-attach your device via USB. | |
202 | ||
203 | Please consult the udev docs of your distro for details. | |
204 | ||
205 | ||
206 | Cypress FX2 based devices | |
207 | ------------------------- | |
208 | ||
209 | Devices using the Cypress FX2(LP) chip without any specific USB VID/PID will | |
210 | be enumerated with VID/PID 04b4:8613 (the default for "unconfigured FX2"). | |
211 | These are usually "FX2 eval boards" (that can also be used as LAs, though). | |
212 | ||
213 | On Linux, the 'usbtest' driver will usually grab such devices, and they will | |
214 | thus not be usable by libsigrok (and frontends). | |
215 | ||
216 | You can fix this by running 'rmmod usbtest' as root before using the device. | |
217 | ||
218 | ||
219 | UNI-T DMM (and rebranded models) cables | |
220 | --------------------------------------- | |
221 | ||
222 | UNI-T multimeters (and rebranded devices, e.g. some Voltcraft models) can | |
223 | ship with different PC connectivity cables: | |
224 | ||
225 | - UT-D04 (USB/HID cable with Hoitek HE2325U chip, USB VID/PID 04fa:2490) | |
226 | - UT-D04 (USB/HID cable with WCH CH9325 chip, USB VID/PID 1a86:e008) | |
227 | - UT-D02 (RS232 cable) | |
228 | ||
229 | The above cables are all physically compatible (same IR connector shape) | |
230 | with all/most currently known UNI-T multimeters. For example, you can | |
231 | use either of the UT-D04 USB/HID cables or the UT-D02 RS232 cable with | |
232 | the UNI-T UT61D multimeter. | |
233 | ||
234 | When using the UT-D02 RS232 cable with any of the supported UNI-T DMMs, | |
235 | you have to use the respective driver with a '-ser' drivername suffix | |
236 | (internally all of these models are handled by the 'serial-dmm' driver). | |
237 | ||
238 | You also need to specify the serial port via the 'conn' option, e.g. | |
239 | /dev/ttyUSB0 (attached via a USB-to-serial cable) or /dev/ttyS0 (actual | |
240 | RS232 port) on Linux (see above). | |
241 | ||
242 | Finally, the user running the frontend (e.g. sigrok-cli) also needs | |
243 | permissions to access the respective serial port (see above). | |
244 | ||
245 | Examples (sigrok-cli): | |
246 | ||
247 | $ sigrok-cli --driver uni-t-ut61e-ser:conn=/dev/ttyUSB0 ... | |
248 | $ sigrok-cli --driver voltcraft-vc820-ser:conn=/dev/ttyS0 ... | |
249 | ||
250 | When using any of the UT-D04 USB/HID cables you have to use the respective | |
251 | driver _without_ the '-ser' drivername suffix (internally all of these models | |
252 | are handled by the 'uni-t-dmm' driver). | |
253 | ||
9b2f03bb UH |
254 | You also need to specify the USB vendor/device IDs of the cable. |
255 | Autodetection is not possible here, since various other products use the | |
256 | USB VID/PID of those cables too, and there is no way to distinguish them. | |
257 | ||
c77ed446 UH |
258 | Since the UT-D04 cables are USB based (but don't use a USB-to-serial chip) |
259 | there is no need to specify a serial port via 'conn', of course. | |
260 | However, the user running the frontend does also need to have permissions | |
261 | to access the respective USB device (see above). | |
262 | ||
263 | Examples (sigrok-cli): | |
264 | ||
9b2f03bb UH |
265 | $ sigrok-cli --driver uni-t-ut61e:conn=1a86.e008 ... |
266 | $ sigrok-cli --driver voltcraft-vc820:conn=04fa.2490 ... | |

269 | UNI-T UT-D04 cable issue on Linux | |
270 | --------------------------------- | |
271 | ||
272 | The UNI-T UT-D04 cable with Hoitek HE2325U (or WCH CH9325) chip seems to have | |
8d3764aa | 273 | a very specific problem on Linux. Apparently it requires to be put into |
c77ed446 UH |
274 | suspend (and woken up again) before it is usable. This seems to be a |
275 | Linux-only issue, Windows is not affected by this since apparently the | |
276 | Windows kernel does this for every USB device, always. | |
277 | ||
278 | Thus, if you want to use any of the UNI-T DMMs with this specific cable, | |
279 | you'll have to run the following script (as root) once, every time you attach | |
280 | the cable via USB. The script was written by Ralf Burger. | |
281 | ||

292 | Enabling multimeter / data logger measurement output |
293 | ---------------------------------------------------- | |
294 | ||
295 | Some multimeters or data loggers will not start outputting measurement data | |
296 | unless a certain action has been performed by the user beforehand. This is | |
297 | usually mentioned in the vendor manual of the respective device, but here's | |
298 | a short list for convenience: | |
299 | ||
1267f128 UH |
300 | - BBC Goertz Metrawatt M2110: Briefly press the "Start/Reset" button on the |
301 | interface panel on top. | |
e6b2b4df | 302 | - Digitek DT4000ZC: Briefly press the "RS232" button. |
c90beca7 | 303 | - Gossen Metrawatt Metrahit 1x/2x devices, driver gmc-mh-1x-2x-rs232: |
fadd0707 MH |
304 | - Power on the device with the "DATA" button pressed. |
305 | - Metrahit 2x devices must be configured for the respective interface type. | |
c90beca7 | 306 | - Gossen Metrawatt Metrahit 2x devices, driver gmc-mh-2x-bd232: |
fadd0707 MH |
307 | - 'BD232' interface: |
308 | The multimeter must be configured for the respective interface type. | |
309 | - 'SI232-II' interface ("PC Mode"): | |
310 | The multimeter must be configured for interface type 'BD232' (all), | |
311 | 'SI232 online' (28-29S) or 'SI232 store' (22-26x). The interface must | |
312 | be configured to the same baud rate as the host (default 9600). | |
313 | Multimeter and interface must be configured to the same address. | |
1267f128 UH |
314 | - Norma DM950: If the interface doesn't work (e.g. USB-RS232 converter), power |
315 | on the device with "FUNC" pressed (to power the interface from the DMM). | |
e6b2b4df UH |
316 | - PCE PCE-DM32: Briefly press the "RS232" button. |
317 | - RadioShack 22-812: Press and hold "SELECT" and "RANGE" together. | |
318 | - TekPower TP4000ZC: Briefly press the "RS232" button. | |
d9e79c51 | 319 | - Tenma 72-7750: Briefly press the "RS232C" button. |
4104ef81 | 320 | - UNI-T UT60G: Briefly press the "RS232C" button. |
7cb69b18 | 321 | - UNI-T UT61B/C/D: Press the "REL/RS232/USB" button for roughly 1 second. |
8769478c UH |
322 | - UNI-T UT71x: Press the "SEND/-/MAXMIN" button for roughly 1 second. |
323 | Briefly pressing the "EXIT" button leaves this mode again. | |
1b142b78 UH |
324 | - UNI-T UT325: Briefly press the "SEND" button (as per manual). However, it |
325 | appears that in practice you don't have to press the button (at least on | |
326 | some versions of the device), simply connect the device via USB. | |
1267f128 UH |
327 | - V&A VA18B/VA40B: Keep the "Hz/DUTY" key pressed while powering on the DMM. |
328 | - Victor 70C/86C: Press the "REL/RS232" button for roughly 1 second. | |
45bb47a7 | 329 | - Voltcraft VC-830: Press the "REL/PC" button for roughly 2 seconds. |

333 | ChronoVu LA8/LA16 USB VID/PIDs |
334 | ------------------------------ | |
c77ed446 | 335 | |
7b356712 UH |
336 | The ChronoVu LA8/LA16 logic analyzer is available in two revisions. Previously, |
337 | the device shipped with a USB VID/PID of 0403:6001, which is the standard ID | |
c77ed446 UH |
338 | for FTDI FT232 USB chips. |
339 | ||
7b356712 | 340 | Since this made it hard to distinguish the LA8/LA16 from any other device |
c77ed446 | 341 | with this FTDI chip connected to the PC, the vendor later shipped the |
7b356712 | 342 | device with a USB VID/PID of 0403:8867. |
c77ed446 | 343 | |
7b356712 UH |
344 | The 'chronovu-la' driver in libsigrok supports both VID/PID pairs and |
345 | automatically finds devices with either VID/PID pair. | |

e311f770 UH |
351 | The Dangerous Prototypes Openbench Logic Sniffer (OLS) logic analyzer |
352 | driver in libsigrok assumes a somewhat recent firmware has been flashed onto | |
353 | the OLS (it doesn't need a firmware upload every time it's attached via USB, | |
354 | since the firmware is stored in the device permanently). | |
c77ed446 UH |
355 | |
356 | The most recent firmware version that is tested is 3.07. | |
357 | ||
358 | If you use any older firmware and your OLS is not found or is not working | |
359 | properly, please upgrade to at least this firmware version. Check the | |
360 | Dangerous Prototypes wiki for firmware upgrade instructions: | |
361 | ||
362 | http://dangerousprototypes.com/docs/Logic_Sniffer_upgrade_procedure | |
363 | ||
364 | Also, you need to specify a serial port for the OLS in the frontends, e.g. | |
365 | using the 'conn' option in sigrok-cli, and you also need to have the | |
366 | permissions to access the serial port (see above). | |
367 | ||
368 | Example: | |
369 | ||
370 | $ sigrok-cli --driver ols:conn=/dev/ttyACM0 ... | |
371 |
