batter charging interface / iota madc block

sorry for not writing anything earlier, but i'm currently moving so i'm a bit short of time. i have been working on the bci and madc block already, so if you are not already done, i'd like to do that. its a bit tricky since one needs to do quite a lot to charge the battery correctly, but in the end we could even charge nimh and i guess small lead batterys also if we want to (with different code). i have done the irq handlers, the charger plug in detection and the async madc stuff is already working. it just needs some cleanup before commit. about the bci stuff: i'm now done reading and understanding the iota datasheets and appnotes (the latter one having invaluable information not in the datasheets). 'just' need to get it written down in code and debug it. ;) summary: if you can live with charging your batteries for another week or 2, just try figuring out the ringer and or vibra for example ps: according the the schem the vibra should be controlled by the auxdac of iota. i poked it and some enable bit few minutes, but couldnt get it doing anything. so there is still a mystery or 2 left. kind regards -- roh
