BoosterPack MKII LCD not working with TM4C microcontroller

Other Parts Discussed in Thread: ENERGIA

I recently bought the Educational BoosterPack MKII for my TM4C123G launchpad. I tried out all the examples that came with Energia 0101E0016. They all seem to work fine (e.g. Joystick and MicrophoneInLEDOut), except for the LCD examples (e.g. LCD_Joystick and LCD_LifeGame). The LCD examples compile and upload fine, but when they are running, the screen only shows white all the time. Has anyone tried this? I suspect that the LCD hardware might be faulty, so I might have to return it.

    Hi Anoop,

    Alternatively, post this at TM4C forum to get more expert advise. As you can see above, this is the MSP Forum.

    Hi,

    I got exactly the same problem.

    How can I fix that?

    Hi, thanks to another member I have been able to fix that. R9 and R10 must be removed from the launchpad. Get a look to TM4C123G sheet and you will realize that there is a short circuit between PD0 and PB6. The same with PD1 and PB7. This affects the LCD and accelerometer of the booster pack MKII.
    R9 and R10 are there for compatibility with older booster packs but should be removed when working with MKII.
    On the other hand I am really surprised by the fact that this simple issue has remained open in the forum during months and months...

    Hi all,

    i can vouch for what Marcos has said about the short between PD0 and PB6 , PD1 and PB7, and the removal of these resistors: it worked straight away for me. i had the same problem with the screen, but after removing t9 and r10- it all worked straight away.

    best.

    ::Update::

    I have just also found out that i have reduced functionality with pushbuttons and joystick's pushbutton when running the 'JoystickDrawColour' program from the MKII example sketches.

    I have not tested this out in other sketches but just thought that I should let you all know that even though my LCD screen is showing the correct picture, my buttons now to not update the screen.

    If anyone has also experienced something similar to this then please share.

    BR,

    I'm getting the same white screen with the msp432 launchpad (red) for all the LCD examples.  It compiles and uploads alright, but just get a white screen on the booster pad mkii.  Anyone else have the same problems?

    Hi Vincent,

    I have exactly the same problem that you have, and I'm using the same parts. Please, if you find a solution to the problem, could you tell me how to fix it?

    Thanks,
