The STM32 USBHID example program shows how to configure and use the USB peripheral of STMicroelectronics STM32F103xx microcontroller. This USB example project implements a Human Interface Device that connects via the USB interface to the PC. A Human Inte
像STM32F103系列的有一个USB Device接口,STM32F407系列的有2个USB接口,既可以作为HOST,又可以作为Device,还可以作为OTG接口。 在Middleware中选择USB_DEVICE设置,在Class For FS IP设备类别选择Communication Device Class(Virtual Port Com)虚拟串口。 参数配置保持默认。 设备描述符保持默认。 四、生成代码 输入项目名...

Complementing and expanding the STM32Cube MCU Package offer with additional embedded software bricks, STM32 expansion packages come either from ...
Could you please tell me if it is currently possible to achieve a composite USB device using the current version of STM32CubeF4 HAL library (so it is just lacking an example demonstration) or the libraries should be changed first (hopefully in the near future) to do that? And, thank you...

After the selection of an empty STM32 MCU or MPU, or preconfigured microcontroller or microprocessor from the selection of a board or the selection of an example, the project is created and initialization code generated. At any time during the development, the user can return to the ...

The example code was developed and tested using the Nucleo-L476RG with version 1.14.0 of the STM32 firmware libraries, and STMCube32IDE v1.0.0. However, it may be re-targeted to other STM32 processors/boards, through the use of the appropriate ST firmware HAL libraries. ...

In this code example, it reads the first backup data register to see if it was written previously and if not, it will unprotect the backup domain and write to it. Once the code is executed the first time, we will do a reset of the STM32 using the button connected to the reset input...
