Esp32 with lcd display using arduino ide

Hi I am Sowmya,

I have a project involving three major components:

  1. Data Acquisition from Arduino nano Board:

    • I successfully retrieve data from an Arduino board using a voltage sensor.
  2. **ESP-WROOM-32 Data Sharing via I2C:

    • I have established a clear path for sharing this data from Arduino nano to ESP-WROOM-32 module using the I2C communication protocol.
  3. LCD Display Integration with ESP-WROOM-32:

    • The challenge arises when attempting to display this data on an LCD board that also incorporates an ESP-WROOM-32 with Wi-Fi capabilities.
    • Specifically, the LCD does not display the value. However, when I upload the factory code (which ensures the LCD driver is correctly initialized) to the ESP-WROOM-32 on the LCD board, it functions correctly.

I followed below link to install driver (ILI9488) for lcd display:-

If i upload sample code for lcd display, its becoming blank screen. Why?

I'm seeking guidance on how to successfully display the data obtained from the ESP-WROOM-32 on the LCD without encountering blackouts. Please advise on the steps to achieve this.

Thank you.

Please post this sketch in full, using code tags when you do, and a schematic of the test system
