Verification

After modifying the screen parameters, you need to verify whether the display is normal. Next, test the screen parameters through the demo of JpegPlayer.
Download from the “test” directory JpegPlayer.rar And unzip:

• Copy the JpegPlayer file from the network disk to Ubuntu and unzip it. Then copy the modified screen parameter and the image of corresponding resolution to the JpegPlayer directory, and rename it to logo.jpg.

• Modify sstardisp.c to include the screen reference header file and set the corresponding resolution

#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
