5、修改Dfuse／src/main.c文件，使用自己定义的按键或者别的进入DFUse状态的条件，我的代码如下：

int main(void) {      GPIO_InitTypeDef GPIO_InitStructure;      RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENABLE);   /* Configure Button pin as input floating */   GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;   GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;   GPIO_Init(GPIOB, &GPIO_InitStructure);   GPIO_ResetBits(GPIOB, GPIO_Pin_1);       //  DFU_Button_Config();   /* Check if the Key push-button on STM3210x-EVAL Board is pressed */   if (GPIO_ReadInputDataBit(GPIOB, GPIO_Pin_1) == 0x00)   { /* Test if user code is programmed starting from address 0x8003000 */    if (((*(__IO uint32_t*)ApplicationAddress) & 0x2FFE0000 ) == 0x20000000)     { /* Jump to user application */       JumpAddress = *(__IO uint32_t*) (ApplicationAddress + 4);       Jump_To_Application = (pFunction) JumpAddress;       /* Initialize user application's Stack Pointer */       __set_MSP(*(__IO uint32_t*) ApplicationAddress);       Jump_To_Application();     }   } /* Otherwise enters DFU mode to allow user to program his application */ // GPIO_SetBits(GPIOB, GPIO_Pin_0);   /* Enter DFU mode */   DeviceState = STATE_dfuERROR;   DeviceStatus[0] = STATUS_ERRFIRMWARE;   DeviceStatus[4] = DeviceState;   Set_System();   Set_USBClock();   USB_Init();         GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;      GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;      GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;      GPIO_Init(GPIOB, &GPIO_InitStructure);   GPIO_SetBits(GPIOB, GPIO_Pin_0);   /* Main loop */   while (1)   {} }
