HI,
I bought This TFT from Coldtears Electronics : http://www.ebay.com/itm/111114349519, that you advise to have.

I need help, because before the screen was displayed I could do the calibration touch but I could not make the calibration butt tft because the screen seems frozen. Now my screen is white I can no longer calibrate. I have white screen when I uploaded FERDUINO CODE, but the uploload is ok .

What should I do.

I use a shield TFT shield with RTC from ITEAD STUDIO.

:-s

Thank you for answering me.

Hi!

Welcome Vicent!

I don't understand your problem with calibration.

Regarding white screen, don't forget to comment this line if you haven't a PCF8575.

#define USE_PCF8575


Too before try install Ferduino you should try test codes.

Best regards.

Hi!

Using examples?

Have you checked TFT model on code?

Have you enabled TFT driver in memorysaver.h?

Also check for update at www.rinkydinkelectronics.com I found there have been support updates done in the last 30 days for coldtears tft and others that is how I fixed some of my issues for ITDB 43 tft.
Happy reefing to all.

My mistake, I thought I had seen a more recent version when looking for drivers for my screen, sorry I look a little closer next time.
