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-FS-Device 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. Note that with this demo only the following configuration are supported: -> 7bit data with parity (Even or Odd). -> 8bit data with and without parity. This demo is using two different methods for the IN and OUT transfers in order to manage the data rate difference between USB and USART buses: - OUT transfers (from Host to Device): When a packet is received from the host on the OUT pipe (EP3), the Endpoint callback function is called when the transfer is complete and all the received data are then sent through USART peripheral in polling mode. This allows all incoming OUT packets to be NAKed till the current packet is completely transferred through the USART interface. - IN transfers (from Device to Host): For IN data, a large circular buffer is used. USART and USB respectively write and read to/from this buffer independently. USART RXNE interrupt is used to write data into the buffer. This interrupt has the highest priority, which allows to avoid overrun and data loss conditions. USB IN endpoint (EP1) is written with the received data into the SOF interrupt callback. Into this callback, a frame counter counts the number of passed frames since the last time IN endpoint was written. This allows to write IN endpoint at separated frames when enough data are present in the data buffer. To modify the number of frame between IN write operations, modify the value of the define "VCOMPORT_IN_FRAME_INTERVAL" in "usb_endp.c" file. To allow high data rate performance, SOF interrupt is managed with highest priority (thus SOF interrupt is checked before all other interrupts). 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 + \HiTOP: contains preconfigured projects for HiTOP toolchain + \TrueSTUDIO: contains preconfigured projects for TrueSTUDIO toolchain + \src: contains the Demo firmware source files Hardware environment ==================== This example runs on STMicroelectronics STM3210B-EVAL, STM3210C-EVAL, STM3210E-EVAL and STM32L152-EVAL evaluation boards and can be easily tailored to any other hardware.
