Problems using 1.77" TFT LCD Screen (no touch)

Other Hardware Displays
1

Hello everyone :slight_smile:

I bought a 1.77" TFT LCD Screen two days ago.
Since then I try to get this little display working, but I'm not succesful at all.

I want to use a Arduino Mega ADK for my project (and tried out a Arduino UNO for this LCD as well). All I want to have is a display to show simple text informations. So I connected the pins like this (Tut: http://arduino.cc/en/Guide/TFTtoBoards) and executed some "first steps" (http://arduino.cc/en/Guide/TFT). The background colour does well, but there are several dark lines on it (with a width of about 6 pixels), I'm not able to get stuff like text, shapes, bitmaps etc. working.

After this blow, I tried out some new libraries (Adafruit-GFX-Library and Adafruit-ST7735-Library ) -> result: blank white screen, still no actions on it. :drooling_face:

The latest step was trying out some possibilities on http://henningkarlsen.com/electronics/library.php and lots of useless youtube clips. :roll_eyes:
Now I'm totally confused and helpless... :zipper_mouth_face:

Is there anybody with same problems/questions or with solutions?
Thanks! :smiley:

Hi!

Problem fixed! :grin:
Just had to install the new Arduino 1.5.6-r2 BETA Software.
Now everything works how it should. 8)
