验证
修改屏参后,需要验证是否显示正常。下面通过JpegPlayer这个demo,来测试屏参。
- 从test目录下载JpegPlayer.rar并解压:
- 将修改好的屏参和对应分辨率的图片拷贝到JpegPlayer目录下,并重命名为logo.jpg:
- 修改sstardisp.c,将屏参头文件包含其中,并设置对应的分辨率:
#define UI_1024_600 1
#define USE_MIPI 0
#if UI_1024_600
#include "SAT070CP50_1024x600.h"
#else
#if USE_MIPI
#include "EK79007_1024x600_MIPI.h"
#else
#include "SAT070AT50_800x480.h"
#endif
#endif
// loacl play res
#if UI_1024_600
//#define LOCAL_VIDEO_W 822
//#define LOCAL_VIDEO_H 464
//#define LOCAL_VIDEO_X 100
//#define LOCAL_VIDEO_Y 60
#define LOCAL_VIDEO_W 1024
#define LOCAL_VIDEO_H 600
#define LOCAL_VIDEO_X 0
#define LOCAL_VIDEO_Y 0
#else
//#define LOCAL_VIDEO_W 640
//#define LOCAL_VIDEO_H 360
//#define LOCAL_VIDEO_X 100
//#define LOCAL_VIDEO_Y 60
#define LOCAL_VIDEO_W 800
#define LOCAL_VIDEO_H 480
#define LOCAL_VIDEO_X 0
#define LOCAL_VIDEO_Y 0
#endif
- 执行make,生成应用程序logo:
- 将logo和logo.jpg拷贝到板子上,然后执行应用程序logo,观察图片是否显示正常:
# ./logo
