Using a Beaglebone or a Raspberry pi would be in many ways better. But I bought the pad expressly for the purpose and would be controlling GRBL through it. It was a poor design decision I guess, but I have it all working except for running my gui on the pad. I am thinking now about using the PI with one of the more powerful Gcode interpreters such as Universal Gcode sender or whatever. Looks like that might be the way to go. But there is added complexity... 1. I would have to purchase a monitor or display for the PI or Beaglebone 2. I would have to purchase the Pi or beagle bone 3. I would have to wire them into the existing stepper controllers 4. I would have to support a keyboard & mouse or trackball and also purchase that device. 5. Checking my local store, the keyboard could be as cheap as $9.00, the Raspberry Pi B+2 is about $35, I could use the SD card from the pad, or buy a new one for about $15, a small monitor rebuilt is $75. A mouse would be about $14 or a trakball for about $22. (wired) , There is a neat small keyboard with trackball for about $40 that would be nice. I like the idea of the trackball for if I have to use a non-touch interface as there is less likely hood of debris mucking it up. There are always trade offs. I'm in the process of moving the code to native Android using ADS. That will take me a couple of weeks since I get tired of learning new stuff. Somehow with 20+languages under my belt, you would think I could figure out a better method... But sometimes the cloud of terminology and thought dust just gets in the way. And by the way, this is a "fun" hack, or at least it was.
