Embodiment Construction
[0031] see figure 1 , a method for automatic resolution adjustment based on Android, comprising the steps of:
[0032] Step 10, dividing a storage sector in the initial blank area of the Android file system, the size of the storage sector is 512 bytes, which is used to store the best resolution of the external display;
[0033] Step 20, read the data in the storage sector by the BootLoader program, and pass this data to the kernel as the startup parameter of the Kernel program;
[0034] Step 30: Start the Kernel program, analyze the parameters passed in by the BootLoader program, obtain the historical resolution, and initialize the LCDC driver, and assign the historical resolution to the CPU output resolution. Since the display driver is later than the initialization of the LCDC driver, the setting can only be done after CPU physical resolution to judge;
[0035] Step 40, obtain the best resolution of the current external display through the display driver, and write the b...
