弱弱请问,我想点7吋TFT屏800x480.
程序从SD卡执行,LCD初始化设置好了,且示波器测量
VSYNC,HSYNC,DCLK,DE波形都有出来.
不过我不晓得颜色数据要写到哪个物理地址?
不晓得底下这几个该如何设置?
S3C_VIDOSD0A = S3C_VIDOSDxA_OSD_LTX_F(0) | S3C_VIDOSDxA_OSD_LTY_F(0);
S3C_VIDOSD0B = S3C_VIDOSDxB_OSD_RBX_F(S3CFB_HRES - 1) | S3C_VIDOSDxB_OSD_RBY_F(S3CFB_VRES - 1);
S3C_VIDOSD0C = (800)*(480);
S3C_VIDW00ADD0B0 = (U32)LCD_BUFFER;
S3C_VIDW00ADD1B0 = (U32)LCD_BUFFER+LCD_BUF_SIZE;
这样设定对吗?
S3C_VIDOSD0A = (0<11)| 0;
S3C_VIDOSD0B = ((800-1) <11) | (480 - 1);
S3C_VIDOSD0C = (800)*(480);
S3C_VIDW00ADD0B0 = 0X51000000;
S3C_VIDW00ADD1B0 = 0X51000000 +(800*480);
