Support for ILI9341_t3

[franzSusemichel]

Hi,

I'm using the library with a teensy 4.1 and ST7920 display. Now i like to use it with a ILI9341 display. ILI9341_t3 library seems not be supported - but TFT_eSPI seems to be fine.

So i tested TFT_eSPI which worked fine - but no look with any of the TFT_eSPI examples in this library. I only get a black screen with blue bars. Increasing the font size increases the size of the blue bars but no luck with displaying the menu.

Any hints for me?

Kind regards

I am using an ILI9341 display but using the Adafruit Library. The problem is Adafruit library is very very slow in comparation with ili9341_t3.
And I am using some critical PIDs calculations that go wrong with refreshing menus. This didn't happen with my old nokia 5110 display.
I would like to use the ILI9341_t3 with my teensy too, which is really fast.

does anyone know how to use it?

Thanks.

Do you have a working example with adafruit display?

Here is a working example. I have tested:
testILI01.zip

PINS, tested with teensy 4.1:
CS 10
DC 20
SDI 11
SCK 13
SDO 12
LED 24
encoderA 21
encoderB 22
encoder button 23

Thx, do you know how i can figure out if led may be switched by teensy pin or needs an extra transistor?
