 *
 * Note:
 *
 * This Case is currently based on BL706_AVB development board with ili9341 controller screen.
 * If you use other hardware platforms, please modify the pin Settings by yourself
 *
 * Your should Short connect func1 and func2 jump cap on 706_AVB Board,and Plug the screen into the HD13 interface
 * Then the hardware for lvgl case testing is available.
