基于S3C44B0的USB测试试验程序源代码，在SDT集成开发环境开发的，修改自Samsung提供的源代码，分开后更便于学习.PC机部分的软件1) LEDDEMO -- 控制 SW44B0板上三个LED的程序2) D12_DRIVER_FOR_WIN98 -- USB芯片WIN98的驱动程序FS44B0X板的USB固件程序--源代码USB_DEMO 使用方法：1）在SDT2.51里调入usb_demo.axf, 运行。2）接上usb电缆，安装win98的d12驱动程序3) 运行 LEDDEMO ，用鼠标点击led1, led2, led3,可以看到FS44B0X板上三个LED亮灭。文件列表: usb实验 .......\D12驱动 .......\.......\win2k_xp .......\.......\........\D12test.inf .......\.......\........\D12TEST.sys .......\.......\win98 .......\.......\.....\D12test.inf .......\.......\.....\D12TEST.SYS .......\LEDDEMO.EXE .......\README.TXT .......\usb_demo .......\........\console.c .......\........\ctrl_set.c .......\........\D12_op .......\........\......\D12Def.H .......\........\......\D12Int.c .......\........\......\D12OP.C .......\........\......\usbdesc.h .......\........\inc .......\........\...\39vf160.h .......\........\...\44B0X.H .......\........\...\console.h .......\........\...\ctrl_set.h .......\........\...\DataType.h .......\........\...\irqlib.h .......\........\...\irqsrc.h .......\........\...\MemCfg.s .......\........\...\Option.s .......\........\SysInit.s .......\........\usbdemo.c .......\........\usb_demo.mcp .......\........\usb_demo_Data .......\........\.............\CWSettingsWindows.stg .......\........\.............\DebugRel .......\........\.............\........\ObjectCode .......\........\.............\........\..........\console.o .......\........\.............\........\..........\ctrl_set.o .......\........\.............\........\..........\D12Int.o .......\........\.............\........\..........\D12op.o .......\........\.............\........\..........\SysInit.o .......\........\.............\........\..........\usbdemo.o .......\........\.............\........\..........\vector.o .......\........\.............\........\TargetDataWindows.tdt .......\........\.............\........\usb_demo.axf .......\........\.............\........\usb_demo.bin .......\........\vector.s .......\usb_demo.axf……
