Oscilloscope V 5.00

Ok, I promised a update, and here it is!

The main change within the new version is a WHOLE new rebuild.  I have taken the great compatibility of the SpecScope and ported this across to the Oscilloscope.  Users who had problems before should now see great stability, opening the Oscilloscope up to the masses.

As always, I’m looking for feedback from wherever it comes from!

Ok, now for some changes you will all see! There is no more sliders to play with, the UI is now fully controllable with just your fingers and the one screen.

  • Pinch to zoom in the X and Y axis
  • Drag left and right to move the trigger position on screen
  • Drag up and down to change the trigger voltage
  • A single tap will pause a signal in Auto mode and look for the next trigger point in Impulse mode
  • Drag markers with a single finger (Available in Trigger Modes only)
  • Long Press on a paused signal (indicated with pause image) to save a 1 second buffer csv file to SD card. (Be patient with the long press, there is a lot of data at 44.1KHz)

So the big change out of that list is the ability to write the buffer to file.  This will be a 1 second snap shot of the current paused/triggered buffer. The trigger point will be centred at 0.5s for analysis before and after the trigger value.  At the current time, the output files are called oscOutput[nubmer].csv, the number is dependant on files previously written.  A message will show the name of the output file.
In the future I will hope to be able to read files back in, also leave the naming up to you!

The screen orientation is now dependant on your native settings, therefore if auto rotate is enabled, the application will work in any orientation.   (Thats one for you guitarist in the video, thanks for the plug)

It is now possible to configure the voltage span of the signal in the settings, therefore if the input conditions are known the oscilloscope can be calibrated correctly . (Quick tip zoom right out in the Y axis and measure a known input voltage against the divisions, remember there are 6 voltage division on screen.)
