>> Real solution is to fix the issue. Agreed. The trouble is figuring out how to fix the solution. We could run the BBB off of a battery, put it in a Faraday cage, and optically couple the gate drive to the BBB, but then you couldn't get to the touchscreen. The issue at hand is that the system is designed to generate large amounts "energy" (e.g. EMI) so we can't solve it by reducing the EMI.
>> Shutting down a touchscreen for x amount of ms will be tough to do. Thanks, that is what I figured. Bare metal programming, this would be simple. But with an OS in the way, maybe not so much.
