Question regarding to LCD for 2x16 Character display

Other Parts Discussed in Thread: MSP430FR6989

Hi everyone,

I have searched a while for the information of using the 2x16 Character display with TI MSP430FR6989, but I haven't found any libraries regarding to the Character display.  I know there is the library for Custom Segmented LCD 6 symbols, 6 alphanumeric characters available on MSP430 lauchpad, But seems like that LCD doesn't include back light LCD.

So my question is

1. Is there any libraries for 2x16 Character display libraries available at TI? Or is there any third party resource available? Or maybe the worst case: I have to write my own version? 

2. Does that 6 symbols, 6 alphanumeric characters LCD has back-light version?  I checked the component in BOM, but couldn't find any parts at digikey or mouser.

Any information would be greatly appreciated!

Thank you!

    I'm not aware of any ready-to-use code from TI for a (HD44780) 16x2 LCD. But those are the easiest ones and the code for it is written quite fast.

    Here is a library that was written for AVR:

    homepage.hispeed.ch/.../avr-lcd44780.html

    You can change it to use it with the MSP, but I would recommend to write your own - you can never learn enough ;)

    And regarding the backlight...it has none and there won't be any replacement. I guess it is a custom part that was manufactured for TI.

    You could look for a EL foil, but to use it you would have to desolder the LCD and remove the morroring foil of the display (if possible at all). Better not do that.

    The LCD controller inside MSP430FR6989 is only capable of handling up to 320 segments of LCD. To display a "character", you need at least 14 segments. Thus you need at least 2*16*14 = 448 segments -- beyond the capability of that LCD controller in the chip.
