The
STM32
USB-FS-Device Library
provides a free, complete firmware package that makes implementation of USB-FS-Device interfaces in STM32 applications quick and easy, that allows developers to painlessly develop any flavor of USB-FS-Device firmware including:
-
Control transfer
with generic device management tasks
-
Interrupt transfer
with HID Mouse/Joystick and Custom HID demos
-
Bulk transfer
with mass storage demo
-
Isochronous transfer
with Audio speaker/streaming demos
In addition, the package provides implementation of DFU for firmware updates on USB-FS-Device, and of the popular Virtual COM (CDC class) for emulation of a classic RS232 interface on USB-FS-Device.
For more details about USB-FS-Device Library and demos implementation, please refer to the User manual "UM0424 STM32F10xxx USB development kit", available for download from the STMicroelectronics microcontrollers website:
www.st.com/stm32
The STM32 USB-FS-Device Library is
USB Full Speed certified and
full CMSIS compliant.
The package contains the following demos:
Note
:
Most of these demos run on STMicroelectronics STM3210B-EVAL, STM3210C-EVAL and STM3210E-EVAL evaluation boards and can be easily tailored to any other hardware. To select the STMicroelectronics evaluation board used to run the example, uncomment the corresponding line in
platform_config.h
file.
Note
:
All demos provided by STMicroelectronics are compatible and tested with Microsoft Windows 2000, XP, VISTA and Windows 7.

Audio_Speaker
|
The USB Audio Speaker demo gives examples of how to use the STM32F10x2/3 USB-FS_Device peripheral to communicate with the PC host in the isochronous transfer mode. It provides a demonstration of the correct method for configuring an isochronous endpoint, receiving or transmitting data from/to the host.

|
|
Audio_Streaming
|
TheUSB Audio Streaming demo gives examples of how to use the STM32F10x5/7OTG-FS_Device peripheral to communicate with the PC host in theisochronous transfer mode. This demo provides possibilities toconfigure high audio quality streaming and low CPU charge using theaudio-class I2S peripheral. This demo runs only on STM3210C-EVAL board

|
Custom_HID
|
This Demo provides a description of how to use the
USB-FS-Device library
on the STM32 devices. The STM32 device is enumerated as HID compliant
device, that
uses the native PC Host USB HID driver.

|
|
|
Device_Firmware_Upgrade
|
This Demo presents the implementation of a device firmware upgrade (DFU) capability in the STM32 microcontrollers. It follows the DFU class specification defined by the USB Implementers Forum for reprogramming an application through USB. The DFU principle is particularly well suited to USB applications that need to be reprogrammed in the field.

JoyStickMouse
|
This Demo provides a description of how to use the USB-FS-Device library on the STM32 devices. The STM32 device is enumerated as an USB Joystick
Mouse, that
uses the native PC Host USB HID driver. The Joystick mounted on the STM3210B-EVAL, STM3210C-EVAL and STM3210E-EVAL boards is used to emulate the Mouse directions.

|
|
|
Mass_Storage
|
This
Demo gives
a typical example of how to use the
USB-FS-Device library
on the STM32 device to communicate with the PC host using the bulk transfer. This demo supports the BOT (bulk only transfer) protocol and all needed SCSI (small computer system interface) commands.

Virtual_COM_Port
|
In modern PCs, USB is the standard communication port for almost all peripherals. However many industrial software applications still use the classic
COM
Port
(UART). The
Virtual
COM
Port
Demo provides a simple solution to bypass this problem; it uses the USB as a COM port by affecting the legacy PC application designed for
COM
Port
communication.
