TMDSDOCK28377D Experimenter’s Kit USB-Serial connection to PC

Other Parts Discussed in Thread: CONTROLSUITE

Hi all,

We are going to buy the F28377D Experimenter’s Kit but I have some questions first.

  1. Is it possible to use the USB connector of the experimenter kit’s emulator for serial communication with a PC? I do not need the built-in XDS100 emulator because I would like to use our XDS510USB emulator via JTAG port of the docking station.
  2. Does the XDS-100 emulator USB port use the SCIA or SCIB UART port or this the USB to Serial port?

Thanks,
Louis

    Using both I'm not sure about. As XDS100 will be live when you connect your USB port. There would be some kind of conflict between XDS100 & XDS510. Hence if you want to use external emulator - you need to use external power supply like an adaptor.

    Yes, SCIA.

    Hi Gautam,
    Thanks for the answers.
    We need the USB port to communicate with a PC based data logger software. So my big plan was to turn off the XDS-100 and use the USB port as UART from SCIA… Where can I find the schematics of the dev. kit?
    Thanks,
    Louis

    Simply download controlSuite and you can find the schematic of the controlCard here:
    C:\ti\controlSUITE\development_kits\~controlCARDs

    Check your version though.

    LouisB,

    The Infosheet in the same controlSUITE directory that Gautam has mentioned and should also help you better understand the kit.

    The controlCARD uses an dual-channel FTDI chip to convert the USB signals from the computer (A) to JTAG signals and (B) to SCI/UART/serial signals.  The xds100v2 driver relies strictly on the JTAG path which leaves you able to use the USB-to-serial path as you desire.

    A:SW1 controls the disabling of either 'channel'.  The infosheet/schematics should make this more clear.


    Thank you,
    Brett

    Gautam,

    Thanks, I found the schematics in controlSuite.

    It seems to me the JP2 USB port and J2 JTAG port of the USB docking station handle the external emulator (like our XDS510USB). If I connect a PC to the A:J1 USB port of the control card then I might be able to communicate with the MCU via SCIA.

    Because both the XDS100 and the external XDS510USB will be connected to the same PC I think I should pick the external emulator in CCS6. In this case the CCS6 will not use the COM port of the XDS100 which will be available for our data logger software?

    Is this true? Have anybody tried this?

    Thanks,

    Louis

    Do try, I've not personally. Share the results with us :)

    Common guys! How do you send the collected and processed ADC-16 samples to a PC via USB-UART port using this experimenter kit? It’s a simple question.

    Brett (Thanks for the answer) is right. The FD2232D is a dual port USB-UART driver chip (Both the control card and the docking station use it). It works like an USB splitter. If you do not use the A port (JTAG) then the B port can be used for SCIA UART. So far it seems to me my idea might work.

    Regards,
    Louis

    Your idea will work.  You just need to put the switches in the correct position (A:SW1 in particular).

    Okay, thanks Brett. I will order the kit, then I will crate a data logging sample APP and I'm going to share my experiences with you.
