Running on a ESP32 and a 2.8" ili9341 touch display

[Frogo27]

Didn't have a CYD but had both ESP32 and a 2.8" ili9341 touch display laying around.

Method:

Used the web-based installer and chose "ESP32-2432S028 (2.8" Resistive)" and flash the firmware. Connect the display to ESP32 using this pinout:

Display Pins

VCC = 3V3
GND = GND
CS = GPIO 15
RESET/RST = EN
DC = GPIO 2
SDI (MOSI) = GPIO 13
SCK = GPIO 14
LED = GPIO 21
SDO (MISO) = GPIO 12

Touch Pins

T_CLK = GPIO 25
T_CS = GPIO 33
T_DIN = GPIO 32
T_DO = GPIO 39
T_IRQ = GPIO 36

After connecting, reset the ESP32 by either pressing the reset button on the ESP32 itself, reset device in the web browser serial and log, or unplugging the ESP32 cable and plugging it back in.

Now it should turn on and load into the CYD-Klipper setup page.

Error that causes it to reboot.

Fixed by using a esp32-wroom-32 instead of a esp32-wroom-32d.

Am guessing the memory address between them two are different. And the CYD uses esp32-wroom-32 not 32d
