Part Number: TDC7200EVM
Other Parts Discussed in Thread: TDC7201-ZAX-EVM, MSP-EXP430F5529LP

Hi Experts,

Our customer asked a couple of questions below:
1) Com connection intermittently disconnected.
   TDC7201-ZAX-EVM and MSP-EXP430F5529LP are utilized. The specified FW was written onto MSP430.
   Could you please let us know what we should check?

2) Would like to retrieve the data from serial communication.
   They would like to get the data like TOF_ONE_SHOT in GUI through serial communication.
   Is it possible to retrieve the data without GUI?

Thank you very much for your kind check.
Best regards,
Hitoshi

    Hitoshi-san,

    You should be able to use COM port terminal GUI to use to serial interface with the EVM.
    You could also get a UBS to SPI modules and communicate with the EVM without the GUI.

    Hi Bharat,

    Thank you very much for supporting.
    We are checking the contents below.
    And we would like to obtain the TOF data somehow.
    Please help.

    CCS project: TCD700EVM_USB
    File: host_interface.h

    We were able to send a command 0x0A successfully by Terminal SW.
    #define Command_LED_Toggle 0x0A // Toggle LED
    // PacketBuffer[0],[1] Command
    Moving forward, we would like to get the TOF data by using the
    #define Command_Start_TOF_One_Shot 5 //Start TOF command
    // PacketBuffer[0],[1] Command
    // PacketBuffer[2],[3] Expected num of stop pulses

    // PacketBuffer[8] Response: start-stop1 data low byte
    // PacketBuffer[9] Response: start-stop1 data high byte
    // PacketBuffer[10] Response: start-stop2 data low byte (only if numstop >= 2)
    // PacketBuffer[11] Response: start-stop2 data high byte
    // PacketBuffer[12] Response: start-stop3 data low byte (only if numch == 3)
    // PacketBuffer[13] Response: start-stop3 data high byte

    We do not know how to configure the necessary parameters to get the one shot TOF data from the EVM by sending Command_Start_TOF_One_Shot.
    Could you please teach us how to set correctly to get the data?

    Thank you very much in advance for your kind support.
    Best regards,
    Hitoshi
