Just a heads up. The sigrok stuff is now committed upstream. http://sigrok.org/gitweb/?p=sigrok-firmware-fx2lafw.git;a=commit;h=ce1d0a869e4761d30b698b6bb1ea015a0470f09e There are some more things I would like to add to the firmware but most of the focus will be on the driver side. Currently there is no calibration but that will eventually be fixed as I now have the proper hardware and tools to do it. |

With much thanks to Joe Vee, there's some progress with the "OpenHantek DDS120". --- Quote ---* Version 0.3.1 * Support for SainSmart/Buudai DDS120 (mmark) * Better support for SainSmart/Buudai DDS120 (CW) * Trigger Support for DDS120 (CW) * Markerslidersteps 0.2 -> 0.1 of DIV (CW) * Select triggervoltage in < 0.05V steps (CW) * Improve trigger stability by excluding false positive cases (JV) * Added falling edge trigger support (controlled by GUI button) (JV) * The other channel now use the same trigger position as the trigger source channel, ensuring that the timing relationship between the channels is maintained. Only the trigger source channel determine the trigger position. This is an important requirement for signals that are generally different (in shape and phase) across the channels. (JV) * Eliminate the "rolling buffer" problem and fix the segmentation fault issue. (JV) * Improvement in the robustness of rising/falling edge detection prior to locating the trigger position offset, especially, for slow signals (e.g 100ms, 200ms timebases). (JV) * Keep the start of displayed waveform (trigger source channel) in level with the trigger position on the slider control. (JV) * The trigger position sliders now work separately and only the trigger source channel controls the trigger position. (JV) * The glitches (discontinuities) in the capture data recurring at around 2KB (combined byte count for both channels) boundaries seems to be a HW/FW limitation of the DDS120 that would be difficult to workaround.

Do you know if this modified version works for DDS140? I cannot seem to make it work, also if there is any more stable version of software. I have troubles getting Triggers (Normal/Single) to work sometimes. I am currently using this version from SainSmart 1.4 https://s3.amazonaws.com/Barsoom/Z0/Z00I0C0Z/Z00I0C0Z.zip https://www.amazon.de/SainSmart-DDS140-Oscilloscope-Signal-Generator/dp/B00HD6F8HY/ref=sr_1_1?ie=UTF8&qid=1465221711&sr=8-1&keywords=DDS140 Many thanks! |

Hello, i have an SainSmart DDS-120. My development environment is debian linux jessie. i'm trying to use OpenBuudai as oscilloscope software, but whatever i try, i got the message that OpenHantek (OpenBuudai) don't find any Buudai oscilloscope. I'm not sure which information i have to give you, but as i said, i had complete compile OpenBuudai and the app is working. I had installed libusb-1.0.20 too. I have no idea what i have to do now. My next idea is to tell OpenBuudai which port it have to use, but don't know how. Have someone any experience with linux and OpenBuudai? Thanks for your help :-BROKE Marko |

Did you set up the udev rules right? |
