Read Registers on MCUFRIEND UNO shield controllers either read as single 16-bit e.g. the ID is at readReg(0) or as a sequence of 8-bit values in special locations (first is dummy)

You have an ID=0x1602 controller. I do not own this 0x1602. I do not have a datasheet. I do not even know the Manufacturer.

Seriously. You should ask your question on the Arduino Forum. After actually "composing" a question. Please quote library version, which "Example" sketch you are running and what is going wrong.

Thanks for quick reply! I contacted the seller but he don't know the driver ic..

Go on. Please ask a question. Please quote library version, which "Example" sketch you are running and what is going wrong.

As far as I know, the 0x1602 works. But I can not fix a problem if I do not know what problem you have.

Likewise, your seller would probably help if you were asking for your money back e.g. if the display does NOT work. If the seller does not know the driver i.c. she can ask her supplier. It costs nothing for a seller to email / phone her supplier. Far better for business than refunding unhappy customers.

Thanks a lot! Your library working for 0x1602! Actually the problem was loose connection! After several attempt of uploading graphictest_kbv sketch three times the tft started working perfectly.. Again fpc connection lost Now I know the problem is in Fpc strip connection!
