If you're still struggling checking out this page, It helped me out. http://joshuagalloway.com/lcd.html Warning, there is error in that link you provided. I said so in my header of my HD44780 lib The datasheet from sparkfun seem to be more accurate, but it did help me a little bit... Just don't fully trust it.

HD44780 LCD Library (16x2 and other models)
mochouinard replied to mochouinard's topic in Code vault
Actually, I wanted it to be that way. And wont be changing it All MSP430 program are REALLY small anyway, there is really no need to shorten the name of functions and variable. I do work on million of line of code software... And in those shorter name for some stuff that come few thousand time are useful. But in this case, it doesn't. You will can run out of flash within a few minute at typing even with those long name anyway... It actually welcome to have longer descriptive information for function name. The goal was not just to make it work, but also provide details information -
This is my attempt for a basic library to control an 16x2 or more LCD display using 6 PIN and controling the hd44780 in 4bit mode. Main .c: http://dl.dropbox.com/u/13477186/MSP430 ... _example.c Library .h: http://dl.dropbox.com/u/13477186/MSP430 ... _hd44780.h Library .c: http://dl.dropbox.com/u/13477186/MSP430 ... _hd44780.c Makefile : http://dl.dropbox.com/u/13477186/MSP430 ... 0/Makefile It working great for my needs so far. Work on my 4 line display too.. My next step will be to make this library support the use of an 595 for 3 pin operation. I would also like some way

I'm wondering, did you 'cut' the hole individually, or it really don't matter that the pins touch the paper ? Might not be a problem for digital communication, but could it cause issue with ADC value ?
-
Correct. They just didn't install the C24 and R34. So I guess everyone could just remove those 2 off their board... BUT just remember to use the in chip pull-up.

FYI, new shipped launchpad doesn't include R34 and C24 that caused this problem. This also mean everyone example code is wrong since they need to put P1REN |= BIT3; P1OUT |= BIT3; to get the pull-high.
