It would be possible to include the pulse trigger? For example in a square wave to trigger a greater or lesser "X" milliseconds of a negative or positive pulse. |

As the DDS120 just streams the ADC-content, this (to my knowledge) can't work. From the code i'd seen, implementing "pre-roll/delay" for trigger would result in a completely rewrite of the code. The code itself is coded with "DMA" and unsafe statements. So if someone knows how to do, i do not. :-// |

No problem man!!! I just thought that with this new accessory would be possible to implement a new trigger in the program. http://www.sainsmart.com/sainsmart-hardware-trigger-module-for-dds-140.html ------- You could tell what function this accessory the link above? Thanks |

This hw-trigger is for the DDS140, which is != DDS120. ;) |

Your SW doesn't recon DDS140, it seems, only "104/140"-specified version will run. So I have to use shipped out one 1.4 from 2014. --- Quote from: mmark on November 09, 2014, 05:52:56 am ---Update: ....... To compile und linux/ubuntu, you need to have libqt4-dev (or libqt5-dev) and fftw3-dev installed. To access the device as a user, add this to /etc/udev/rules.d/50-sainsmart.rules: --- Code: ---#add SainSmart DDS120 and DDS140 to group plugdev #DDS120 SUBSYSTEM=="usb", ATTR{idVendor}=="8102", ATTR{idProduct}=="8102", GROUP="plugdev" #DDS140 SUBSYSTEM=="usb", ATTR{idVendor}=="8312", ATTR{idProduct}=="8312", GROUP="plugdev" --- End code --- and make sure that your user is member of the plugdev group. --- End quote --- All done, it compiles fine. My DDS140 is recognized as Buudai104 :), unfortunately the screen is empty, no waveform and no waveout on the device. Do I need FW-extraction and loading scripts like on the Hanteks? |
