  1. For the analog components that are there on things like the Educational BoosterPack, a simple resistor ladder divider should work fine to scale down the voltage. It would be nice to at least have an option like that. I can give you an op-amp circuit that will scale 3.3V down to 1.8V. For me it'd be really handy. The cape identification EEPROM would also be very handy for allocating the pins and configuring drivers.
  2. I haven't read this full thread, but I did get a board for a few minutes today to play around. I haven't yet understood how everything is wired. It seems like the analog pins are not yet connected on the board that I got. Also, it seems some of the pins are tied to the eMMC and therefore can't be used with Black unless you boot from an SD card and disable the eMMC. Check out the code and let me know your thoughts. I'm going to start looking at the LCD interface next. http://beagleboard.org/support/BoneScript/educationalBoosterPack/ The blue LED is tied to an eMMC pin.
