My version

I made a version that is easier to work with in any GUI (IMHO) and an example app that reads 6 analog pins.

Here are some features: 

  logic analyzer mode that shows 1's and 0's clearly.
  pause frame
  save frame
  configurable pin-count
  use as many pins as will fit on screen (tested with 12 at 800x800, seems ok)
  shows volts, based on scaling settings
I set it up to be useful as a logic analyzer for digital pins, or oscilloscope for analog.

I'd like to add more features like extended frame logging (continuous) and detecting bytes in logic probe view, like SPI/i2C. I'd also like to add a parallel mode, for reading 8-pins at a time into a single byte.
