If it has been processed/manipulated it isn't raw! :-)
If you look inside the Adafruit code it simply multiplies the BBB's 0.000 to 0.999 value in AINx by 1800 to get what it calls a raw value, you can't process a non-raw value more and get a raw value. -- Chris Green ยท -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
