I'm a hobbyist with a recent BBB and I want to use a couple of ADC channels in real time (alternate). As nearly as I can tell, this is not supported by the two risk units.
Have I missed something?

BBB and Linux are new to me. One of the things I would like to do is compute a ratio between two voltages, each of which might exceed 1.8 VDC. One solution might be to use DACs to sent feedback voltages to operational amplifiers that are supplied by 1.8 VDC. The goal is to determine the ratio as quickly as possible and without waiting for Linux to get around to it (waiting for the ADC to happen).
