On youtube I found a video where the 1kHz test signal looks like it should, so maybe my device is faulty Monday crap. Depending on signal and noise the value decreases mostly between 20% and 40%. Changing to 200mV/div should halve the value. Depending on signal form and noise the value raises about 10-30%. result > 6.5V -> blank screen, loud beeps and permanently flashing warning 'Out of range!' 2nd, relative value, by 10 divided signal in 100mV/div area Changing the screen divider to 50mV/div should double the value. Two examples: 1st, absolute value, USB Voltage / AVR supply, roundabout 5V (4.8V - 5.13V may occur) 5Volts are 'transformed' to 6.4V - 6-5V., three possible scenarios: - resulting voltage curve will be displayed - 6.4V Curve is displayed and a wrning message is blinking, sometimes paired with beeps. As long as I'm able to work bugs and glitches are a only a minor problem. within the loupe func you should be able to scroll left and right.unfortunately the arrows are greyed out always.

At least there are two probs, HW and SW! For ex. Let me know if you want to assist me in the bringup.Surely, of course I did so. Maybe some minor difference here and there. Since the initialization works fine in Logic140, we should be able to port it in OpenBuddai and a quick glance of the code seems like the sequence is similar. The device was detected but data capture is failing with similar error as you posted. Thus,I wanted to tryout OpenBuddai.I was able to compile it on linux and run it.

Also zooming/panning function seem to be dsyfunctional. See snapshot attached, for the case when the test signal from the scope is probed in CH1.Though I think the GUI as well as the implementation is not great especially for the oscilloscope version, since there is lot of data loss happening (The red region which is seen in the gui). The gui seems to work and connect to the DDS140 scope when invoked as a root.

Hi, As far as the Logic140 code is concerned, I was able to compile it under Linux-Ubuntu using neatbeans and gcc compiler.The JNI library had to be ported to call corresponding functions from libusb available in Linux, compared to the winusb implementation provided.
