打开“driver”文件夹 在文件目录下打开“Terminal”或者“终端”窗口 1.输入“make”执行指令 2.输入“sudo make load”执行指令 3.输入“sudo make unload”执行指令 输入“ls /dev”执行指令查看设备驱动 显示如下内容则VCP驱动安装成功 如显示如下内容则显示系统自带有CDC驱动,VCP驱动未安装成功 需执行以下步骤,...
CDC类vid:用于基于STM32F3的设备的pid 、、、 我使用STM32CubeF3 V1.9.0中的示例通过删除uart外围管理来尝试CDC类。 PC检测usb设备的vid:pid 0483:5740。Linux自动识别CDC类(STMicroelectronics STM32F407),加载cdc_acm模块,并创建ttyACM0 VCP。Windows的各种版本是否会自动识别设备(并将其与CDC驱动程序相关联...

If you use this VCP driver, please check that the CDC-ACM driver was not installed for the USB UART devices mentioned above. You can use command "ls /dev/ttyACM*" to confirm that, to remove the CDC-ACM driver, use command "rmmod cdc-acm". ...
1、在 Gadget Device 创建时,首先把 Device 加入到 udc_list 链表,然后尝试和 gadget_driver_pending_list 链表中的 Driver 进行 match(): usb_add_gadget_udc() → usb_add_gadget_udc_release() → usb_add_gadget():int usb_add_gadget(struct usb_gadget *gadget){/* (1) 将 device 加入全局链表...

文章目录一.USB虚拟串口原理简介二.接收函数实现源码三.小结 一.USB虚拟串口原理简介 USB虚拟串口,简称 VCP,是 Virtual COM Port的简写,它是利用 USB的CDC 类来实现的一种通信接口。 我们可以利用 STM32 自带的USB 功能,来实现一个 USB虚拟串口,从而通过 USB,实现电脑与 STM32的数据互传。上位机...
[ 166.220294] cdc_acm 2-1:1.0: ttyACM0: USB ACM device As of MacOSX, The built-in CDC driver on MacOSX doesn't accept any CDC composite device with IAD yet, still on the latest 10.6.5 As MCP2200 takes this composite device configuration, MacOSX fails on this device. ...
Interestingly, the JLink Plus that I have with VCP enabled enumerates with the correct maxpacket size of 512 under Linux (I haven't had a change to test the USB CDC comms using the JLink Plus). To help debug this issue please see the attached l...
