我在编译USB程序的时候,遇到下面图片中的问题,
(原文件名:2010-4-9 10-15-56.jpg)
可我认为usb_devices.h是公用的文件,在其他项目里调用这个头文件的时候是没问题的,为什么在这里就有问题了呢?请问谁能帮我分析一下这个问题?
编译指向的错误是这一句 BOOL USB_APPLICATION_EVENT_HANDLER(BYTE address, USB_EVENT event, void *pdata, WORD size);
这个函数的说明是/*******************************************************************************
