Re: ILI9341 SPI wont work
OK, i found the Problem.
The supply voltage was higher then 3V ......
But the display is very very slow, I try to colorize the background by draw a rectangle with red background color but it will take along time ......
Has someone an Idea or is that normal for this type of display?

Hello CSM2711

Try the next:
1. Move the background colors/draw to init stage (out of the main loop).
2. The Clear iLi display function takes a lot of time, don't use it, just 'print' the empty space over the text (erase it).
3. Use for communication between the microcontroller and iLi9341 the level shifter.
PS
I use iLi with Arduino.
The display is good for my weather station, but not fast.
