MIPI-DSI之DCS相关

概念
MIPI DCS: MIPI Display Command Set

DCS读取多个字节
DCS读取多个字节，需先通过MIPI_DSI_SET_MAXIMUM_RETURN_PACKET_SIZE(0x37)设置要读取的最大字节数

C

//...
 ret = mipi_dsi_set_maximum_return_packet_size(state, 2);
 if (ret) {    
     printf("mipi_dsi_set_maximum_return_packet_size ,error=%d!!\n", ret);
     return ret;
 }
 ret = mipi_dsi_dcs_read(state, 0x04, &dwin_id[0], sizeof(dwin_id));
 if (ret <= 0) {    
     printf("mipi_dsi_dcs_read ID[04h] ,error=%d!!\n", ret);
     return ret;
 }
 printf("mipi_dsi_dcs_read ID[04h]=%x, %x\n", dwin_id[0], dwin_id[1]);
 //...
