MSP432P401R: MSP432P401R: TExaS Display does not indicate any activity

Part Number: MSP432P401R

I am unable to get the TExaS display software to work properly on Windows 10. I am following the instructions of Lab 1, 

but am unable to detect any data being sent over the USB port. 

I am running texas display version 2.4, and have been unable to see data on any of the COM ports that I have...

Looking for some help in understanding what I am missing... The MSP432P401R is running...

  • Scott,

     This software is not a TI product. Please contact the author. Just from Googling for that software, I get the address

    for Jonathan Valvano at UT Austin(linked here).

  • Scott,
    I contacted the RSLK team here, and learned that the TExaS software is associated with their kit (I'm in the MSP432 apps team proper, which is a different group). They will pick up ownership of this thread. Please go ahead and hit "reject answer" on my previous post, and the RSLK will respond from here on. Sorry for the confusion.

  • Per Bob L, rejecting this answer - and thanks for getting to the right folks...

  • Hello Scott,

    Sorry to hear about your issues running the Texas Display. Please follow steps as mentioned in lab 1

    The first step is to activate the TExaS project, and open the TExaSmain.c file. There are three main programs in this project. Edit the LogicAnalyzerMain function so it is called main, and edit the other main to be Lab2main. Notice the MSP432 will be running at 48 MHz and the logic analyzer is configured to display Port 1. When it is running the seven bits of P1.6 – P1.0 will be streamed to the PC at 10 kHz. The logic analyzer works whether the pin is an input or output. In this example, P1.0 is an output (to the red LED) and P1.1/P1.4 are inputs from the two LaunchPad switches.

     

    int LogicAnalyzerMain(void){

    uint32_t status,delay,data;

    Clock_Init48MHz(); // makes bus clock 48 MHz

    LaunchPad_Init(); // use buttons to step through frequencies

    TExaS_Init(LOGICANALYZER_P1);

    data = 0;

    while(1){

       status = LaunchPad_Input();

       switch(status){   // negative logic on P1.1 and P1.4

         case 0x00: delay=1000; break; // neither switch pressed

         case 0x01: delay=2000; break; // SW2 pressed

         case 0x02: delay=3000; break; // SW1 pressed

         case 0x03: delay=4000; break; // both switches pressed

       }

       Clock_Delay1us(delay);

       data = data ^0x01;

       LaunchPad_LED(data); // toggle red LED

    }

    }

     

    You can see the various options for the logic analyzer by looking in the TExaS.h header file. These are the choices you have when configuring the TExaS.

     

    enum TExaSmode{

    SCOPE,             //8-bit oscilloscope on J3.26/P4.4/A9

    LOGICANALYZER,     //7-bit logic analyzer

    LOGICANALYZER_P1, // 7-bit logic analyzer on P1.6-P1.0

    LOGICANALYZER_P2, // 7-bit logic analyzer on P2.6-P2.0

    LOGICANALYZER_P3, // 7-bit logic analyzer on P3.6-P3.0

    LOGICANALYZER_P4, // 7-bit logic analyzer on P4.6-P4.0

    LOGICANALYZER_P5, // 7-bit logic analyzer on P5.6-P5.0

    LOGICANALYZER_P6, // 7-bit logic analyzer on P6.6-P6.0

    LOGICANALYZER_P7, // 7-bit logic analyzer on P7.6-P7.0

    LOGICANALYZER_P8, // 7-bit logic analyzer on P8.6-P8.0

    LOGICANALYZER_P9, // 7-bit logic analyzer on P9.6-P9.0

    LOGICANALYZER_P10, // 7-bit logic analyzer on P10.6-P10.0

    LOGICANALYZER_P4_765432, // 6-bit logic analyzer on P4.7-P4.2

    LOGICANALYZER_P4_765320, // 6-bit logic analyzer on P4.7-5,3-2,0

    LOGICANALYZER_P2_7654 // 4-bit logic analyzer on P2.7-P2.4

    };

    You may have to select a COM port that is available and then run the TExaS display

    Hope this helps.

    Thanks & Regards,
    Ayesha

  • Thank you - I missed the code change...
