Graphics Test ILI9341 TFT LCD SPI Display

Interfacing a 2.8 inch SPI TFT that has a ILI9341 chip to an Arduino Uno.

Step 1: Things Used in This Project.

1. Arduino Uno

2. 240*320 2.8" SPI TFT LCD Display Touch Panel

3.Jumper Wires

4.Breadboard

5. Resistors 1K Ohm

Step 3: Interfacing a 2.8 Inch SPI TFT That Has a ILI9341 Chip to an Arduino Uno.

// All you need is eight 1K resistors. Most people use a 4050 IC. //

For 5v operation, leave open/cut J1.
For 3.3v operation, solder J1.

i think that the resistors can be avoided if you dont solder the jumper J1 in the back of the screen

I don't know, it's not working, only white screen and black flickering.

Could you explain why the resisters are needed? Also, How would you use the 4050 IC rather than the resisters. I just purchased two of these LCDs from Amazon and was going to return them because I didn't think they worked. I have the resisters at home and will try the them first. It would be great to see the same schematic picture with the 4050 as well. Most importantly though is the why. I really want to understand why it's all needed and why I'm not seeing anything wired up without the resisters. Thanks !!!!

The display control pins work on 3V, would work with 3.3V, I bought level shifters breakout boards and now building the setup.

The breadboard friendly resistors are really cool, are they from the Pi hut?

[deep_parun]

No. I bought it from DFRobots .Yes they are breadboard friendly resistors .

thank you, found them on AliExpress ..dfrobot ecell kits
