It makes the USB device look like a serial port (NO serial cable connectors:You can see the data transferred to and from via USB instead of USB-to-USART bridge connection). This example loops back the contents of a text file over usb port. To run the example, Type a message using the Pc's keyboard. Any data that shows in HyperTerminal is received from the device. This VirtualComport_Loopback Demo provides the firmware examples for the STM32F10xxx, STM32L15xxx, STM32F30xxx and STM32F37xxx families. - OUT transfers (receive the data from the PC to STM32): When a packet is received from the PC on the OUT pipe (EP3), EP3_IN_Callback will process the receive data. To receive something to the STM32 data are stored in the Receive_Buffer[] by calling CDC_Receive_DATA() - IN transfers (to send the data received from the STM32 to the PC): When a packet is sent from the STM32 on the IN pipe (EP1), EP1_IN_Callback will process the send data. To send something to the HOST we put the data in to the Send_Buffer[] buffer and call CDC_Send_DATA() 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 ================== + \inc: contains the Demo firmware header files + \EWARM: contains preconfigured projects for EWARM toolchain + \RIDE: contains preconfigured projects for RIDE toolchain + \MDK-ARM: contains preconfigured projects for MDK-ARM toolchain + \TASKNIG: contains preconfigured projects for TASKING toolchain + \TrueSTUDIO: contains preconfigured projects for TrueSTUDIO toolchain + \src: contains the Demo firmware source files Hardware environment ==================== This example runs these STMicroelectronics evaluation boards and can be easily tailored to any other hardware: -
