Don't read the buttons from GPIOC but from DBOP_DIN (all directional buttons + select) Still missing hold, rec, volume up and volume down Read microsd Tuner is a si4700 but seems to suffer from the same problem than e200v2 Sound works TODO: missing buttons, lcd yuv, test lcd performance (the c200v1 lcd performance has decreased since r21321 : needs to be investigated) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21330 a1c6a512-1295-4272-9138-f99709370657
