I am using UART0_BASE and UDMA to transfer data to computer and it is working perfectly(on TM4C123). I am trying to use USB output as a virtual comport to transfer traffic from UART0_BASE to USB. I studied usb_dev_serial example and it configure the USB output perfectly. I have two question:
If I want to send data to host computer or receive from it, do I need to write or receive data via UART buffer? I used "UARTCharPut(UART0_BASE, 'S');" but it doesn’t work. If I have to use other methods please let me know how I have to configure UDMA, as well.
In the computer the name of com port appear TivaWareUSB Serial Port. How can I change it?
Thanks
