Hello,

1. no,this GPRS Shoield is only newer version as far as i read! U need to put an battery inside. do not know why, but without was not working. the battery in the rtc timer keeps the clock working when power is disconnected.

2. no, should make no difference.For testing you need only connect the ardiuno to power!

3. Timer connection to arduino:
   SCL = A5
   SDa = A4
   VCC = VCC
   GND=GND

thanks a lot man!

I have connected everything, downloaded the code from github, it was compiling fine.

BUT when I upload the code to Uno I only get a white screen. No texts at all, just plain white screen. Again there were no compilation errors at all.

I am using TFT v2, could this be a problem? I have tried downloading TFT_v2 library and changing the include TFT.h to include TFT_v2.h in the .ino file.
But then I am experiencing many compilation errors.

Please help me!

thanks,
T
