Yeah, after coming back a day later to play with this further the contrast is still super dark and when I disconnect the ground pin the contrast then goes way too light. I am thinking that if the contrast is supposed to be internally set then there isn't an easy way to mess with the contrast and I probably just got a bad screen.?

Yeah, this LCD however has pin three listed on the datasheet as a n/c. Just because it is a 3.3v LCD instead of 5v.

IT WORKED! I am so stoked. Sorry that I have to bother everyone with my stupid errors. I feel dumb. So I think this version, the 3v version, of the LCD is supposed to have the contrast internally set. But the screen is really dark and you can hardly see the text? Any ideas on how to fix that? Should I just start messing with pin 3, which is supposedly a no-connect? edit* I disconnected the Vss pin on the screen and now my contrast is awesome. However, I am baffled how this screen works without having the ground pin connected to anything? And why would that screw up my contrast?

It's the operational enable signal. Which is falling edge triggered. So you take it high, turn on whichever signals and then drop it low.

I am trying to use my launchpad with a g2152 to write to an LCD. I have a 3.3volt LCD from New Haven Display (http://www.newhavendisplay.com/specs/NHD-0216HZ-FSW-FBW-3V3C.pdf). I am pretty sure I have it wired up correctly, I have torn it all down and reconnected everything just in case. This thing is driving me up the wall. The code is pretty much ripped straight from NewHaven's forums and double checked with the datasheet. I don't know where I could have gone wrong. Any hints? //--------------------------------------------------------- /* 8_bit_character.c Program for writing to charac

Blue Hash, you were right. oPossum, thanks for that delay loop. Very clean.

I just edited and added the #includes, with that it is my full test program. I just installed CCSv5 on this computer today so all the defaults are intact. I went into project properties and looked at optimizations and it was at level 0. So I don't think so. Is that what you are talking about?

I feel like an idiot asking this question. I had this program working on my msp430f2274. Now I am trying to play with it using CCSv5 and putting it on the launchpad. For some reason it is skipping over my subroutines. #include #include //*********************************************************************** void delaySec(int n){ int i; int j; int k; for (i=0;i for (k=0;k<1000;k++){ for (j=0;j<100;j++){ ;} } } } void main(void) { WDTCTL = WDTPW + WDTHOLD; //disable watchdog delaySec(2); P1DIR = 0xFE; //set p1.6 as output,and P1.0 as input. P1OUT = 0x40; //p1.6 is pul

It wasn't compiling, that was the problem. I ended up downloading CCSv4 and it threw the same error. The path defined was weird because the windows account I was using is named "MOM & DAD" with spaces. Code Composer stopped looking when it saw the space after MOM so it couldn't find the file. I logged on to a different user account on my computer and that solved the problem. Thanks.

I am able to build the project, but it is not compiling. I think a ".out" file is supposed to be created somewhere but it isn't.

I got a TI launchpad and am trying to run one of the test programs they have on their wiki. I followed their walk through but when I debug I am getting an error. "MSP430: GEL: Encountered a problem loading file: C:\MSP430_LaunchPad\Labs\Lab2\Project-TS\Debug\Temperature_Sense_Demo.out Could not open file" I have tried making new projects in other directories. Tried the "Blink the LED" they give you. All to no avail.. I opened the debug folder and sure enough I can't find any .out files. I am sure there is a simple solution for this? Anyone know what's up?

Allright I tried throwing a pot on there and I couldn't get any gray squares to show up. This LCD from NewHaven, http://www.mouser.com/ProductDetail/New ... 2s1Q%3d%3d just has the contrast pin as a no connect. Could it be that the contrast for this other LCD is the same deal and that it is internally set? I am baffled as to why I cannot get this thing to work..

So, I thought that maybe I was just getting the contrast off on this thing. It's supposedly a 3.3v model so I hooked up an external power supply to Vo and raised the voltage to 4.2, 4.5, 4.8, 5.0 Still nothing. Am I supposed to see black bars or anything? The back-light is on but that's about all I can get. Any ideas would be so awesome.

So I made those changes and still cannot get the LCD to print any characters. Is there anything else obvious that I have done wrong or am missing?
