Hello guys!
I have a problem with using my screen with the TFT library: I do not find the model parameter, i searched in the informations of the library but i didn’t found. I’m pretty sure that it is compatible. Could you help me please?

Hi,

Did you try the demo code ? robotshop.com/content/ZIP/de … shd028.zip

Do I have to put an SD card in my screen?
Is it compulsory to put an SD card to make the screen work?

My screen is turned on but the code doesn’t work… Anyone to help me please?..

Hi,

Normally, you can use the screen without an SD card to draw lines or texts using the TFT library. Please note that the sample code is designed for Arduino Mega board.
Could you please specify what board you are using with the TFT shield ?
And when you say the screen is turned on, what does it display ?

Regards,

Hi,

I’m not having much success getting this module to work with an arduino uno.

Both with the sample code provided and with an UTFT demo I only get a white screen.

Using the example code provided what are the modifications needed to make it work with the UNO? The pins assignment look ok: RS = A5; WR = A4; CS=A3; RST =A2. I’ve commented out everything in the sample that is not related to the LCD and still only get a white screen.

Using utft, I used the demo UTFT_Demo_320x240.ino and changed the display init to: UTFT myGLCD(ITDB24E_8,A5,A4,A3,A2);, also only get a white screen.

Any ideas what could be going wrong?

thanks.

Hi,

This TFT LCD Touch Shield is not 100% compatible with Arduino UNO.
The UNO needs modification to clear the USB-B connector to work with this shield:

Your shield is probably not completely stacked on your Arduino UNO with the USB-B connector on it preventing the connection.

Hi,

thanks for the quick reply.
My UNO has a mini USB type B connector so the shield clears it with no problems. I’ve also tried on another UNO with shield stacking headers and get the same result, so I don’t thinks it’s a connection issue.
It’s kind of not relevant for this, but I have several other LCD shields that work with this UNO but they use another controller.

would there be any test code I could try to use to identify if the controller is not being initialized correctly or if it is defective?

thanks.
