TMS320F28335: PIN J14 Physical Connection Part Inquiry

Kyle Kozielski

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE

Hello,

I need to send an order to get components so I can start programming this control board. I was hoping someone can help me with what this part is (where the arrow is pointing), or at least what the specific name of this kind of part so it can narrow my search down. It looks like some kind of female housing for the cable to connect to. I've noticed that its also the same as the other ones on pins J8, J9, J10, J11, J12, and J13. Any help is greatly appreciated.

Edit: I have found this and wondering if it is what I needed: https://www.digikey.com/product-detail/en/molex/0050579404/WM2902-ND/115057

    Kyle,
    Is this a TI reference design or kit on TI.com? If so we usually have the BOM included as part of the design files in C2000Ware install directory. If you can give me the part number of the design I can point it out.

    Best,

    Hi Matthew,

    This is the TMS320F28335PGFA. I have been asked by my supervisor to use this already assembled control and order the correct parts so that way I can connect it to my computer and start learning how to program it. I am just unsure how to accomplish this since there is no USB port, however we don't have access to the experimenter kit. Is there certain parts for this board I need to connect to my computer?

    The part I am specifically asking for is the J14 pin. I have found this: https://www.digikey.com/product-detail/en/molex/0050579404/WM2902-ND/115057 , but I am not sure how I would solder this to the board.

    Thanks,

    Kyle

    Kyle,

    Thanks for the reply, so this is a custom board that you/your company has made.  Connection to the device would be done through the JTAG port, using a stand alone emulator like the XDS110 http://www.ti.com/tool/TMDSEMU110-U .  

    I would look at the board schematics and verify where the JTAG signals(TMS/TDI/TDO/TRSTn/TCK) from the F28335 are routed.  Do they go straight to this header, or otherwise?  If they go straight to the header, then you will need to make a cable/connector that brings these out to a 14 pin header to connect to the emulator shown above.

    I can help with understanding the test connectivity to the F28335 or other C2000 MCUs, but I'm not in a posistion to evaluate the correct connector, etc that has been implemented on a non-TI PCB.  You should have access to a BOM and schematic that can help you re-order the correct components for your PCB.

    Best,

    Matthew

    Hi Matthew,

    Thanks so much for your detailed response. You have cleared a lot up for me.
