430BOOST ADS1118 Trouble with demo code

Other Parts Discussed in Thread: MSP430G2553, ADS1118

I have been trying tirelessly to change the text on the LCD screen in the ADS1118 MSP430 Boosterpack using the demo code. Once I finally downloaded and installed all of the extra packages I needed, the LCD screen would still not display what I wanted it to. It powers on, but the display remains blank. I tried loading the original demo code back onto the device, but nothing happened. Is there an updated version of the code that possibly does not use Grace? I am using a rev 1.5 MSP430G2553 launchpad. I noticed that the demo code was last modified in 2012.

The program has definitely been loaded onto the launchpad and nothing was changed in the code, but it still won't put the old program back on without flashing the program back to the device. I really just want to change what is being displayed on the LCD right now.

HELP!

  • Hi Caitlyn,

    The code hasn't changed since it was released in 2012.  You should have been able to import the project into CCS and used the GRACE configuration from that project.  Believe it or not, the GRACE tool is the easiest way to setup the configuration to the device.  The LCD is connected to an SPI USCI_B0 peripheral.  If you imported the project, you should have just been able to use the commands in the project.

    I will help you if I can.  First I would make sure that the project imported correctly by compiling it and downloading the program to the Launchpad which requires flashing the device.  If this works, then you can try something simple to learn how the LCD commands work.  The LCD is

    NHD-C0216CZ-NSW-BBW-3V3

    And you can run an internet search for the device for further information on the operation of the LCD.  This might help with understanding on how to talk to the LCD. 

    Best regards,
