Follow-ups

--- Sonic Zhang 2010-08-18 05:18:30

Fixed. The predefined i2c address 0x2c doesn't match the configuration of ad5280

PINs AD0 and AD1 on the tftlcd addon board. Both AD0 and AD1 are of voltage

3.3V, which means the i2c address should be 0x2F.

i test this case again and it indeed fixed, so i closed the bug.
