How to work with TFT touch display and Arduino uno

by sini1104 on Thu Apr 15, 2021 3:39 am

Hello!

I started the first time with including touchscreens in my projects, so I don't really know which components are necessary to get everything done.

I have an Arduino Uno and I need a touchscreen with my own visualization on it. I don't need an OS on, just an own programm, where i can switch between pages, load images from my Arduino and just send information back if I press on an button.

I have found some touchdisplays in the adafruit store, but how is the best way to establishe a communication with my arduino board with it?
Most of the TFT Displays have this 40 Pin connector and some of these have also I2C or SPI separatly.
How can I use this protocols ? Do I need an own breakout board for it?


Thank you an best regards
Sini

I suggest you look at the Arduino tft/touchscreen shields such as https://www.adafruit.com/product/1947, https://www.adafruit.com/product/1651, or https://www.adafruit.com/product/802.

Hello Dave!

Thank you for your suggestion.

I have already a own designed PCB with my Arudino on it and I would like to buy just this touch display : https://www.adafruit.com/product/1774 and extend my PCB so that I can plug it just on it, and also maybe use the library vom adafruit.
Is there a layout design of this touch display, so that I can realize that?

Thank you!

Best regards
Sini

I think we can connect the TFT LCD to Arduino through the serial port

Just like some serial screens.
