ILI9488 GPIO output gpio_num error

[LukasLuck]

Hello Bodmer,
I am using ILI9488 and ESP32. I have the PIN connections as below and I have modified user_setup.h accordingly.

I tried to run Test_Touch_Controller.ino and get responses on serial monitor such as:
Starting...
E (10) gpio: gpio_set_level(226): GPIO output gpio_num error
E (10) gpio: gpio_set_level(226): GPIO output gpio_num error
E (21) gpio: GPIO can only be used as input mode
E (73) gpio: gpio_set_level(226): GPIO output gpio_num error
E (457) gpio: gpio_set_level(226): GPIO output gpio_num error
E (457) gpio: gpio_set_level(226): GPIO output gpio_num error
x: 0 y: 0 E (579) gpio: gpio_set_level(226): GPIO output gpio_num error
E (579) gpio: gpio_set_level(226): GPIO output gpio_num error

LED on ESP32 is blinking continuously.

Pressing on display, but nothing changes on serial monitor

My question:

1. what would be the cause of that error (how to fix)?
2. Do we need to define T_IRQ, LED pins in script/ user_setup

Thank you very much in advance.

Best regards

Lukas

Typically this error means the GPIO number was out of range or specified as -1

T_IRQ is not used bt the library
If the LED control pin is connected to the processor then the pin should be specified in the setup.LED
