I bought a 2.8" TFT LCD touch screen from ebay cheap but it has no documentation or datasheet with it showing pin names, registers, ect...
It seems to be a standard drop-in touch screen and I haven't had any luck finding a similar screen with a datasheet or header and c files.
I was wondering if anybody could lead me to software or a datasheet.
Thank you
PS
I have the Arduino Uno R3. Does the WP at the end of the LCD make a difference?
Maybe it helps if you told us what you bought. A link could be useful.
I can't find the exact link that has a WP at the end but here is a similar where this one says for Arduino Uno OE:
Does the shield state www.mcufriend.com on the back?
If so, a google search for arduino mcufriend 2.8 tft reveals some links.
Start digging 
mcufriend 2.8 inch TFT LCD display issues - Displays - Arduino Forum might get you on the way with the adafruit library (reply#3); the code snippet reveals that it should be possible to get the driver ID out and next you can look for the datasheet.
2)
240×320 2.8” TFT Shield driver 4535 for Arduino can give you some pointers as well
3)
Finally got the touchscreen shield to work
4)
Other links might reveal relevant information as well.
I have no experience with TFT so can't help further. My first reply was based on the fact that if we know nothing about what you bought, we can't help at all.
Good luck.

If you don't come right, add a post to this thread; others with more experience might be able to help.
This is great. My LCD does not have the www.mcufriend.com on it but the board and pins are identical so now I have a good thread to follow.
Yes, happy digging for me!!! 
<-- me being happy
Thanks so much
Got it!
Your 1) link worked. Now I can step through the code.
THANK YOU
