LAUNCHXL-F28027: Use the FTDI chip as virtual COM port on the PC and communicate using with the F28027 using it

Part Number: LAUNCHXL-F28027
Other Parts Discussed in Thread: C2000WARE

I'm sure this has been asked before but I could not find it:

I see from the schematics that the UART is connected to the FTDI FT2232H which in turn connects to USB.

Is it possible to use/see the FTDI chip as virtual COM port on the PC and communicate using it with the F28027?

And if so, is there any support for this in the libraries and if, which?

    Kustaa,

    Yes it is possible to use the secondary channel of the FTDI as a COM port back to the PC, either while debugging (using the primary port of the FTDI as the XDS100v2) or standalone.

    I would start with the examples in C2000Ware http://www.ti.com/tool/C2000WARE with a path of:

    C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2802x\examples\drivers\sci_echoback

    This will simply echoback whatever the PC terminal input is, but will give you a starting point to develop whatever comms you need on the UART, try different baud rates, etc.

    Note that the application programmed into the flash at the factory also has a simple UART implementation as detailed here.  

    http://www.ti.com/lit/ml/sprz376/sprz376.pdf

    You wouldn't need to run CCS/C2000Ware just to observe this is working if that helps.

    Best,

    Matthew

    Thanks Matthew, the notification system did not inform me about your answer so I'm a bit late. Anyways, the links you provided look promising, I'll be back if I cannot proceed but for thank you very much.
