项目工程中加入\stm32_mw_usb_device master\Class\CDC\Src 中的 usbd_cdc.c，并修改相应头文件名称和路径，解决编译问题；另外，由于移除了usbd_hid.c文件，所以在应用层也需要并屏蔽掉HID相关的应用层操作；主要比如HAL_GPIO_EXTI_Rising_Callback()，然后编译，会遇到下面3个错误：...
对于第一个错误，USBD_ClassTypeDef USBD_HID 修改为USBD_ClassTypeDef USBD_CDC，用USBD_CDC替换...
多路CDC USBD_CDC_CfgFSDesc 多路复用器 在测试测量相关应用中,模拟开关和多路复用器有着非常广泛的应用,例如运放的增益调节、ADC分时采集多路传感器信号等等。虽然它的功能很简单,但是仍然有很多细节,需要大家在使用的过程中注意。所以,在这里为大家介绍一下模拟开关和多路复用器的基础参数。 在开始介绍基础的参数之前...
