I'm in the process of building a USB composite CDC + MSC device on the STM32F4 Discovery board but am having trouble getting windows to recognise it. Using USBlyzer all the descriptor info seems ok but windows will only recognise the CDC (virtual com port). The port gets enumerated and ...
在Device里面，有core跟class，class里面有CDC的东西，core是低层代码 另外example里面也有一些东西 ...
I am basically trying to implement a USB device (CDC-ACM to be precise) that utilizes suspend/wakeup. I am usingthe ''STM32_USB-Host-Device_Lib_V2.1.0'' and looked into the HID example for help. Unfortunately there is no example that shows the USB HS with suspend/wakeup using an ...
USB Host Library: add CDC class USB Device Library: add composite class Use latest version of STM32F1xx, STM32F2xx and STM32F4xx drivers Use FatFs R0.11 Examples Update all examples to run on STM324x9I-EVAL (STM32F429) board Add one example (VCP_Loopback) for STM32446-EVAL (STM...
I can't assign the USB endpoint address for the CDC ACM calss driver. The below is the compile command and configuration CLI: west build -b stm32f4_disco zephyr/samples/subsys/usb/cdc_acm The prj.conf file with the content: CONFIG_STDOUT...
Although the ST USB library implements the standard USB CDC class and Windows has drivers for it, it will not recognize the device without an inf file specifying which driver to use. Download and install theSTM32 VCP driversto get Windows to recognize your device. If the device is still not...

因为某些需求,需要在STM32上开发USB驱动,从网上找了个CDC的例子,又找了VC的上位机进行通信测试,把我两百多的下载积分都用光了,哎真是坑啊,有些下载了基本不能用,不是endpoint的通信。 第一个坑:USB开发时,其系统频率必须使用168MHz,具体我就不细说了,可以参考下面的... ...
STM32F469 重定向printf到USB CDC 将STM32F469的printf重定向到其USB CDC上的工程源码(Keil5),可以直接使用USB当串口调试工具,printf格式化输出。 上传者:jayyf时间:2017-11-24 STM32F4芯片固件库(STM32F4xx-DSP-StdPeriph-Lib-V1.8.0) STM32F4芯片固件库(STM32F4xx_DSP_StdPeriph_Lib_V1.8.0) ...
