S5PV210 u-boot LCD驱动 自动更新增加进度条

这里使用的是 ICOOL210开发板 之前我写过一篇2416的u-boot LCD驱动 具体请参照 http://blog.csdn.net/hclydao/article/details/17911747

过程基本都是差不多这里实现的效果跟之前的2416的不一样主要是把之前的串口打印的信息显示在LCD上这样自动更新的时候会占用不少时间所以这里我去掉了这个功能在上面加了一个进度条

具体修改过程如下

首先在drivers/video/下增加gzsd210_lcd_pg.c 内容如下

}

这里主要需要用到的函数有

gzsd_lcd_init

gzsd_setprogress

先调用 gzsd_lcd_init进行初始化 然后在需要设置进度的地方使用gzsd_setprogress设置即可

Makefile增加一条如下

COBJS-$(CONFIG_VIDEO_GZSD210PG) += gzsd210_lcd_pg.o

然后须要在配置文件里增加如下宏定义及相关声明

#define CONFIG_LCD_AT070 1

#define CONFIG_LCDBPP_16 1

#define CONFIG_VIDEO_GZSD210PG 1

#if !defined(__ASSEMBLY__)

extern void gzsd_setprogress(int percentage);

extern void gzsd_lcd_init(void);

#endif

效果如下
