ILI9488 display is not working. (AEGHB-252) #277

Closed nikhil-robinson closed 1 year ago

nikhil-robinson commented 1 year ago

Environment

Problem Description

Trying to test ili9488 display with the example screen not able to get any display out. my connections are correct was able to test the wiring with different display ili9431 with same example and it works. The display also works tested with an Arduino board.

Expected Behavior

generate mandelbrot

Actual Behavior

Gray screen

Steps to repropduce

  1. Compile the example from esp-iot-solution/examples/screen for esp32s3

Hi @nikhil-robinson, the "Display" component is not maintained anymore. We strongly recommend you use "esp_lcd" component to develop the LCD.

Please refer to the example and doc.
