ESP32 touch screen boards

Good afternoon fellow flowcode forum users.

I recently bought two of these touch screen boards and found limited information about them.
ESP32-2432S028R (resistive) & ESP32-2432S032C (capacitive)

I've linked a github page based off of one of the boards i found along the way if its useful to anyone.
https://github.com/witnessmenow/ESP32-C ... ow-Display

This is the original alibaba page for them
https://www.alibaba.com/product-detail/ ... 91286.html

I am wondering if anyone has had any experience with them and would be willing to share some example projects below so i (as well as others, if useful) can see how to structure a flowcode to get this board working.

I've never programmed any screens before and looking at examples really helps with understanding how it all works.

here are some pictures of the boards.

Thanks all.

Hi

They look quite interesting.

From what I see they use an ESP-WROOM-32 chip which is supported in FC, and also the display seems to be based on the ILI9341 (SPI) which is again supported in FC.

I don't seem to see any reference to the Touch Screen though, but perhaps the generic resistive one could be used?

You would need to establish what pins on the WROOM are used to communicate with the display, and then set the FC display component to the same. Similarly if you can establish the pins for the Touch Screen set the FC component to the same.

Plenty of WiKi examples on using the display.

Regards

Thank you for your pointers. i am currently experimenting with the examples found on the WIKI, with no luck so far but im sure i'll get there.

For any others in the same case as me, this information i found helpful. still looking for some example projects of working flowcode projects using these boards however.
