我碰过过这个问题,在QUALCOMM平台上,
就是如下刷屏宏代码写的不对引起的. 好好看看你的刷屏代码.
#define DISP_SET_RECT(start_col, start_row, end_col, end_row ) do{ DISP_CMD_OUT(TOVIS_NM220DN5_START_HOR_ADDRESS) DISP_DATA_OUT(start_col) DISP_CMD_OUT(TOVIS_NM220DN5_START_VER_ADDRESS) DISP_DATA_OUT(start_row) DISP_CMD_OUT(TOVIS_NM220DN5_END_HOR_ADDRESS) DISP_DATA_OUT(end_col) DISP_CMD_OUT(TOVIS_NM220DN5_END_VER_ADDRESS) DISP_DATA_OUT(end_row) DISP_CMD_OUT(TOVIS_NM220DN5_RAM_ADDR_HSET) DISP_DATA_OUT(start_col) DISP_CMD_OUT(TOVIS_NM220DN5_RAM_ADDR_VSET) DISP_DATA_OUT(start_row) }while(0) |
