@lore I'm glad you managed to get the desired hardware. Serial Com is likely the best route to take because of the bandwidth of the standard. It's rather odd that they would not include it over USB. There was probably an Engineer who cried in the shower when they decided to exclude that on a Digital Signal Processor.
@lore It's as if companies hate their customers. Reversing is a potential option depending on the laws.
Sell a complete product and no more money can be made. Sell an incomplete product and sell licenses for software that makes it work for a good income stream. Don't forget to include legal landmines in all of it that prevent reversing from being feasible. Ah that's the modern model.
