Hi,
I’m using a msp430f169 and the 3.3v Serial Enabled LCD from sparkfun. So i should be able to just send a ASCII to the LCD and it should be displayed. Nothings happening on the LCD though. I checked that I am sending at 9600 baud so I don’t know what’s wrong. Any ideas?
Do you get the splash screen when the LCD is first powered up? Have you tried changing the contrast?

I figured something out.
The LCD I bought was a 3.3v one but I get the splash screen when I power it with 5V. 3.3v logic is still not working on it so did i just get the wrong lcd or does the 3.3v lcd still only work with 5v?
Ok
I adjusted the contrast to pretty much maximum and can barely make out the splash screen at 3.3V. Backlight control commands that worked before are no longer working now.
alright, it’s working now. needed a longer delay between each character that i was sending…stupid
