Folks,
We need someone who perhaps has read the entire datasheet (joke) and can write some form of extension (I don't really care how it is implemented) that will acquire a burst of 16-bit data (e.g., 512 or 1024 words) from user-specified, likely contiguous (but potentially arbitrary) pins of a Teensy 3.6 (say 25 = MSB, 39 = LSB) at a precise rate specified in MHZ (e.g., 1, 2, 10) and provide a digital strobe each time (HIGH->LOW->HIGH) to allow maximum acquisition speed from parallel ADCs. We have budget to pay someone, and will freely share the work product with the community.
If you care to look, I have a thread on what I could accomplish with the available (and known to me) methods:

We need to get much faster. The chip should be able to do it, but it may require some fancy programming outside of the Arduino IDE .
It will be important to make it shareable broadly and accessible to users of moderate skill (no editing of libraries or soldering on the Teensy board please).
Any positive, constructive discussion would be highly appreciated. This will enable good-performance, open-source and commercial spectrum analyzers, oscilloscopes, and potentially other instruments.
Thanks,
Greg
