文档介绍：1. If your WVGA panel physical scan line is 480 and pixel is 800. Please modify FRAME_WIDTH and FRAME_HEIGHT in your LCM driver code ex: #define FRAME_WIDTH (800) #define FRAME_HEIGHT (480) 2. If you want to use portrait display as default, please modify MTK_LCM_PHYSICAL_ROTATION = 90 or 270 to match your orientation of Platform. ex: alps\mediatek\config\#Project\ MTK_LCM_PHYSICAL_ROTATION = 270 MTK_LCM_PHYSICAL_ROTATION = 90 3. If you want to use landscape display as default, please modify MTK_LCM_PHYSICAL_ROTATION =0 or 180 to match your orientation of Platform. ex: alps\mediatek\config\#Project\ MTK_LCM_PHYSICAL_ROTATION =0 MTK_LCM_PHYSICAL_ROTATION = 180 4. According to2 and 3, please don't modify system property to rotate display ex: alps\mediatek\config\#Project\ #=270 // please remove it (0,0) (0,480) (800,0) (800,480) (0, 0) (0, 48 0) (80 0,0 ) (80 0,4 80) (0, 0) (0, 48 0) (80 0,0 ) (80 0,4 80) (0,0) (0,480) (800,0) (800,480) (0,0) (0,480) (800,0) (800,480) 5. According to2 and 3, please calibrate your g- sensor and m- sensor as default display orientation. ex: If your orientation of default display is portrait, like below figure. Please calibrate G- Sensor and M- Sensor to0 under this condition. 6. Please porting below files to guarantee MTK_LCM_PHYSICAL_ROTATION config is work. It also works under Factory mode and Recovery mode. alps\mediatek\source\kernel\drivers\video\ alps\mediatek\source\kernel\drivers\video\ (0, 0) (0, 48 0) (80 0,0 ) (80 0,4 80) 1.
