首先我在STM32下移植了一个UCOS，而且在另外一个工程里也调试好了STM32 HID这块，但是当我把usB这块移植到UCSO下就发现系统彻底挂了。链接电脑后显示没有发现硬件设备，并且LED灯也不亮！！！我怀疑是启动文件的问题，但也不知道如何修改！
我在主函数下加的是： USB_Interrupts_Config(); Set_USBClock(); USB_Init(); 三个函数，结果系统就挂了！ 以下是我的启动文件请看下： ; If you need to use external SRAM mounted on STM3210E-EVAL board as data memory, ; change the following define value to '1' (or choose ENABLE in Configuration Wizard window) ;// DATA_IN_ExtSRAM EQU 0 ;

不用ucos的时候,能成功么?

不用UCOS的时候，在UCOS工程下可以跑程序点亮LED流水灯，然后加入USB工程里的三个函数就挂了！在USB工程里可以正常发送数据上位机接收到！

我现在发现一个问题：莫非UCOS下的USB和STM32例程里的USB不一样？？？呜呜！！~~~
