Read display identification information (04h)

Hi,

Made a new board to 3,15V with resistors. 2,7k and 4.7k (to GND). No result at all. The Arduino gives all registers back as 00h. Tried both VCC to 3,3V and 5V. No result on the screen too.

When I put it back to the 5v board, it gives out the old results, as shown above. The ILI responses but nothing on the screen.

Any one a clou?

Regards
Sven
