2.2tft display to arduino uno r3

tolisn63: The connection must be done as below but keep in mind that you need a level shifter between your display pins and the arduino pins because your display is 3.3 V and you arduino is 5V.

with the below connections and the level shifter you can use hardware SPI.

the screen signals -----> MOSI MISO SCK DC Cs must be connected to the Uno pins -----> 11 12 13 9 10

If i connect it so will it work to with the bitmab example? That needs sd card interface.

Must i define the needed pins or not? If yes: how And must i change anything in the code? If yes: what must need a change?

Any?

I think i will buy a cd4050 to level convert. but how to connect it?
