屏幕为:AT070TN83 v1.0
以下是对LCD参数的配置:
#elif defined(CONFIG_FB_S3C_LCD800480)
#define S3CFB_HFP 19 /* front porch */
#define S3CFB_HSW 27 /* hsync width */
#define S3CFB_HBP 37 /* back porch */
#define S3CFB_VFP 10 /* front porch */
#define S3CFB_VSW 13 /* vsync width */
#define S3CFB_VBP 26 /* back porch */
#define S3CFB_HRES 800 /* horizon pixel x resolition */
#define S3CFB_VRES 480 /* line cnt y resolution */
#define S3CFB_HRES_VIRTUAL 800 /* horizon pixel x resolition */
#define S3CFB_VRES_VIRTUAL 960 /* line cnt y resolution */
#define S3CFB_HRES_OSD 800 /* horizon pixel x resolition */
#define S3CFB_VRES_OSD 480 /* line cnt y resolution */
#define S3CFB_VFRAME_FREQ 60 /* frame rate freq */
#define S3CFB_PIXEL_CLOCK 4//(S3CFB_VFRAME_FREQ * (S3CFB_HFP + S3CFB_HSW + S3CFB_HBP + S3CFB_HRES) * (S3CFB_VFP + S3CFB_VSW + S3CFB_VBP + S3CFB_VRES))
很奇怪的是开机的logo倒是很正常。
屏幕如下图所示,花屏了。不知道这种情况是那边程序照成的。
