TDC1000-C2000EVM: Pins Information

TI-CSC
Genius 13035 points
Part Number: TDC1000-C2000EVM
Other Parts Discussed in Thread: TMS320F28035, TDC1000

Hello E2E Experts,

Good day.

The board that I am dealing with called TDC1000-C2000 has a lot of pins whose functionalities I do not know. The datasheet and other relative documents do not explain the functionalities as well. Can you please help?

So, I know that I have to use the J5 port to use the transducers but for all other pins, I have no clue. For example J1 port, TP (1-6), JP1, TP22, TP23 and TP15, and TP17.

Also, I am using the board to generate 1Mhz signals from one transducer and receive it through another and thus measuring the time taken by the signal to reach from one transducer to the other. So instead of detailing every pin/port that I mentioned, you can only explain the pins/ports I need to be using.

Thank you in advance.

Regards,

CSC

    Hi CSC,

    Thank you for posting to the Sensing Forum!

    Regarding the pins that you mentioned:

    • J1 is the JTAG connection that allows for external debugging
    • TP (1-6) are testing points allowing you to monitor input pins on the TMS320F28035
      • For more detailed information on what input pins these Test Points are being connected to, please see the schematic for TMS320F28035PAG Figure 17 - Schematic 2
    • TP15 provides a test point to the V3P3
    • TP17 provides a test point to DUT_VDD
    • TP22 provides a test point that is connected to the TDC1000's STOP pin (through a buffer) that is used as a time of reference to end a TOF (time-of-flight) measurement
    • TP23 provides a test point that is connected to the TDC1000's START pin (through a buffer) that is used as a time of reference to start a TOF measurement
    • JP1 is a jumper that allows you to choose between an internal/external clock

    For your scenario, TP23 and TP22 should allow you to monitor the TOF measurement between the transducers.

    Best,
