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. This Virtual COM Port Demo provides the firmware examples for the STM32F10xxx family. More details about this Demo implementation is given in the User manual "UM0424 STM32F10xxx USB development kit", available for download from the ST microcontrollers website: www.st.com/stm32 Directory contents ================== + \include: contains the Demo firmware header files + \project: contains pre-configured projects for RVMDK + \source: contains the Demo firmware source files Hardware environment ==================== This example runs on STMicroelectronics STM3210B-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. How to use it ============= + RVMDK - Open the VirtualCOMPort.Uv2 project - In the build toolbar select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - STM3210E-EVAL: to configure the project for STM32 High-density devices - Rebuild all files: Project->Rebuild all target files - Load project image: Debug->Start/Stop Debug Session - Run program: Debug->Run (F5) NOTE: - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. ******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE******
