开发环境:ADS 1.2/SDT 2.51 GUI测试，由于没有触摸屏，所以将触摸屏的代码给屏蔽了； 请将FS44B0II开发板连接好交叉网线、直连串口线、电源， 并连接好G57液晶屏，同时还要连接好背光电源； 然后在BIOS的命令窗口里面敲netrun命令； 点击FS44B0_G57_uCGUIuC-GUIFS44B0_G57_uCGUI_DataDebugRel目录下： 批处理文件FS44B0_G57_uCGUI.BAT 下面你就可以看到液晶屏上面显示优龙标志 它会延时一两秒中进入下一个画面，逐步延时GUI的各项功能，请耐心观看； -Development Environment: ADS 1.2/SDT 2.51GUI test, because there is no touch screen, it will be touch screen to shield the code Please FS44B0II development board to connect a good cross-network lines, direct serial lines, power supply, and connect a good G57 LCD screen, at the same time, good backlight power supply connection and then in the BIOS command window knock netrun order Click FS44B0_G57_uCGUIuC-GUIFS44B0_G57_uCGUI_DataDebugRel directory: batch file FS44B0_G57_uCGUI.BAT below you can see the LCD screen above shows excellent signs that it will delay Liuzhou 1 two seconds to enter the next screen, and gradually delay the GUI features, please be patient watch
