Re: 2.8 TFT V2 Touch Screen Need a Library

No apology needed - been there, done that! First, make sure you have only one folder containing the library files, and make sure you only have one .cpp and one .h file in that folder. Take any others out of the path - stick them in an unrelated location. The Arduino is relatively clueless when there...

Re: 2.8 TFT V2 Touch Screen Need a Library

Hello James, I'll assume you are using the example programs supplied by Seeed. I don't have a drawText function - did you mean drawChar? I just ran both the "text" example which uses drawChar, and the "drawNumber" example and have no compile errors. Your error message refers to line 284 of TFTv2.cpp...

Re: 2.8 TFT V2 Touch Screen Need a Library

The stdint.h library is built into the IDE. You don't need to manually install it. The demos will run as supplied.

Re: 2.8" TFT touch Shield v1 w/ Arduino UNO r3

Hi, I am using your 2.8'' TFT Touch Shield v1.0 with my Arduino Uno. Using the Arduino 1.0.5 software running Windows. I have read through all the previous questions other people have asked, but haven't found anything helpful. I imported the library files I got from the wiki site provided. After it...

Re: 2.8" TFT touch Shield v1 w/ Arduino UNO r3

I just want my new touch screen to display something besides white light. Please send me a good example code (however basic) and the appropriate libraries. I just need a boost to get started. http://www.seeedstudio.com/wiki/2.8''_TFT_Touch_Shield_V1.0 Additional examples included with the libraries.

Re: 2.8" TFT Display Shield Issue

Richard,
That's great news!

I'm glad you let the forum users know how you solved the errors. So often people get help, then never return to let anyone know if the suggestions actually worked, leaving everyone in the dark.

Regards,
John
