The resolution of the whole device is 480x960, which is divided into two 480x480 screens. The first control screen is on the left, and the GPS map display screen is on the right. The display and black screen of the second screen can be controlled separately.

Since the simulator uses the code of lvgl 9, and the SDK of BK7258 is based on lvgl 8.x, it needs to be properly modified to port.
