SUMMARY

The discussion centers on selecting a suitable platform for displaying a single image on a 2.8" TFT touchscreen. Users suggest that while Arduino can be used, it may struggle with memory and speed constraints, making Raspberry Pi a more viable option for this project. The original poster is a beginner with no prior experience in microcontroller programming and is seeking guidance on how to proceed. Recommendations include considering electronic picture frames as an alternative solution for simplicity and cost-effectiveness.

PREREQUISITES
  • Basic understanding of microcontrollers (uC) and their programming.
  • Familiarity with Raspberry Pi and Arduino platforms.
  • Knowledge of display technologies, specifically TFT screens.
  • Experience with power supply options (battery vs. USB).
NEXT STEPS
  • Research Raspberry Pi GPIO programming for display control.
  • Learn about interfacing TFT displays with Arduino and Raspberry Pi.
  • Explore electronic picture frame options and their specifications.
  • Investigate power supply solutions for portable projects.
USEFUL FOR

Beginners in electronics, hobbyists interested in microcontroller projects, and anyone looking to create simple display solutions using Raspberry Pi or Arduino.

first of all- Hello! I was wondering if anyone can help me, I am looking to get a miniature display (2.8" TFT display, annoyingly touch screen but oh well) all I want to do is display a single image for a small project of mine but I'm not sure how to approach this, do i use a RaspberryPi or Arduino?? if so what else will I need? Its also preferred if its cheaper than say something like a RaspberryPi as I might build it more than once for others.

PS. I have never done anything like this :D

Welcome to PF.

What have you found with your Google searches so far? Can you please post links to the top 3 display candidates that you have found so far?

And are you saying that you need to drive this display from an Arduino uC, but you have no experience in uC programming projects?

Is this a schoolwork assignment? What class is it for? Does anybody else in the class have uC programming experience?
 
These are the Displays i was looking at only having knowledge on needing a display and the size i need:

I'm not saying i need an Arduino to drive this no, i have no knowledge on any of this at all, its why i came here to learn and get some help, Arduino is something i have just picked up from online and believed that it is something that would work for my case, this isn't for anything in particular like school work, this is me purely wanting to learn how to do this for personal use

That's helpful, thanks.

But can you say more about your project? What have you done with uC projects so far? What embedded languages have you programmed in so far? (C, Python, etc.)

What development system and development platform/board are you planning on using for this project?

It's very hard for us to give you useful tips without understanding exactly where you are in your learning, whether this is for schoolwork, and what development platform you want to use...
 
"I have no knowledge on any of this at all, its why I came here to learn and get some help"-
any and all information is helpful. This is what I am aiming to recreate (from a game) I have 3d modeled it within fusion 360 and then decided that I want to make it more exciting than just a boring prop, so i wanted to make the screen as seen on the picture display just a single image and the the rocker switch beside it just turn it on and off. that is my project and having no previous knowledge or work on this I thought coming to a forum for help would be my best bet at learning how to.

An electronic picture frame would do the job. They come as small as 1.5 inches, and some cost less than $20. But you need to decide two things.

  1. Power: battery or USB from a charger?
  2. Is the picture stored on a SD card, or is the frame connected to a computer where the picture is.
Here's a search that will show you very many products that might do it.

Due to memory and speed constraints this kind of image will be difficult to display using Arduino. Raspberry Pi would be a much better option.

(That's ignoring many other problems already addressed in the questions asked earlier).
 
Thank you for the help everyone, I really appreciate it!
