We did that for one of our projects, and it works great. Also keep in mind that this would not slow down reading from the ADC much, if at all. A simple "line select" with a GPIO based multiplexer could be really fast. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
