CCS/BOOSTXL-K350QVG-S1: Problem with LCD Display and MSP430F5529

Does the calibration step at the beginning of the demo work?

Hi 

I have try the BOOSTXL-K350QVG-S1 with MSP430F5529's Launchpad and it works well. 

Do you download the project named "MSP-EXP430F5529LP_GrLibExample"?

Have you remove the jumper JP8 for the LED?

Best regards

Gary

Thanks for replying so quickly!

Yes we are working with that project.

No we haven't removed it yet. Should we do it? Now we noticed that there a sort of adhesive tape at the back of the display and we don't know if we should also remove it.

English is not my mother tongue, please excuse any error on my part.

Thanks again, Micaela

Hello,

Looking the code we realized it doesn't enter the function  touch_calibrate(); we think that is a little weird  because there is no condition. However we don't fully understand the previous code (this is copied below).

We know the first condition is met, but the second condition is not true. We don't understand what the program is trying to do there.

English in not my mother tongue, please excuse any error on my part.

Thanks, Micaela. 

   /* Check if the screen has already been calibrated. */

    if(touch_calibrationData.key == TOUCH_CALIBRATION_KEY)
    {
        /* Return if the user is not manually requesting calibration. */
        if(GPIO_getInputPinValue(TOUCH_SW1_PORT, TOUCH_SW1_PIN))
        {
            return;
        }
    }

    /* Wait for SW1 to be released. */
    while(!GPIO_getInputPinValue(TOUCH_SW1_PORT, TOUCH_SW1_PIN))
    {
        ;
    }

    /* Calibrate the touch screen. */
    touch_calibrate();
}

Hi 

I think the demo code will have no problem. Your issue should be related with the hardware. I don't change anything on the  BOOSTXL-K350QVG-S1  and just plug it on the msp430f5529's Launchpad. And then download the demo code and it works.

You should check the soft PCB connector like below

Hi Gary,

Sorry for the delay in responding, we wanted to verify that the display had the connector you mentioned.

Indeed, it has, it and is the same as the one you showed us in your photo.
We do not remove it or anything similar.
Should we do something with that connector before connecting to the launchpad?

Another thing we detected is that the demo never enters the part of the screen calibration, which is rare because that function is present in the code.

Thank you for your answers.
Regards, Micaela.
