5" HMI Display communicates with another ESP32 board

lamle · March 6

Hi everyone,

I have recently bought an Elecrow ESP32 5" touchscreen 800x480 SPI HMI display. I see the SKU on my display is WZ8048C050.

I have learned how to use SquareLine Studio to upload a display with buttons with the video here (https://youtu.be/TcWvxw61U_w?si=6ElMholp4nBipCgu)

Now, when I click a button on the screen, or when I go to a specific screen, I want to make some calls to other functions that I have developed on another separate ESP32 chip. Or, when it goes to a screen, it calls the other ESP32 to get the data, and populate the received data onto the screen.

How can I connect my ESP32 chip with the ESP32 chip of the 5" display? Should I plug the cable that comes with the display into GPIO_D socket and connects to 4 pins on my ESP32 chip?

Maybe do you have already an instruction online somewhere how to connect? Thank you.
