编写的例程是使用FSP提供的usbhcdc中间件,实现了一个可使用usb串口设备的usb主机。 首先在RT-ThreadStudio上新建一个基于开发板的项目,选择CPK-RA6M4开发板,建立一个模板工程。编译下载后,可以看到LED灯在闪烁,同时可以在串口终端上使用rtt的FinSH控制台。 下一步,打开RASC,在stacks页面,添加一个usb hcdc的驱动栈。

问题1:在唤醒后,Pipe报了这个错误:W (53056) USB_HCDC: line 1030 Pipe: bulk_out HCD_PIPE_EVENT_ERROR_XFER。之后再进行联网,一直连接不上。 问题2:在进入休眠时,需要对USB进行什么操作吗? 代码: Code:Select all #ifdefCONFIG_DUMP_SYSTEM_STATUS/* Configure the button GPIO as input, enable wakeup ...
首先说一下STM32的USB库的初始化操作，MX_USB_DEVICE_Init函数中使用USBD_RegisterClass函数注册绑定了...
