Best STM32 Discovery kit for a TouchGFX word puzzle port?

[RobPatt]

Hi everyone,

I am relatively new to the ST ecosystem, coming primarily from a web development and programmatic software background.

I recently built a browser-based daily logic game tailored for my local market called hang 5. The core mechanics rely on a responsive visual letter grid, basic string matching for user inputs, and a specific vowel-penalty state machine.

As a hobby project, I want to build a physical, standalone desktop version of this puzzle using an STM32 board and a small capacitive touch TFT display. I've been researching TouchGFX to handle the UI, as it seems more than capable of replicating the clean CSS grid layout I am currently using on the web version.

Before I purchase my first board, I have two quick questions:

1. Which STM32 Discovery kit would you recommend for a beginner wanting to utilize TouchGFX for a snappy, interactive 2D touch grid?

2. The game requires a daily dictionary array of about 2,500 words. Is storing this plain text array directly in the internal flash memory going to be an issue on entry-level MCUs, or should I be looking at boards with external memory?

Thanks in advance for the hardware guidance!

Welcome to the forum.

I wouldn’t recommend a beginner to leap straight into a TouchGFX project!

You really need to spend some time getting used to the embedded environment first.

Take a look at this thread:

 

In particular this post on getting started with your first few projects.

 

Good luck!

Hello ​@RobPatt and welcome to the ST community,

Look at this video showing the capability of the STM32F469 DISCOVERY board with TouchGFX.

Especially the Bird coin game shown at 1:24.

You can also use STM32F769-DICO board for more performance: see this video. (the Bird coin game shown at 8:24 / puzzle game at @7:47)

Hope that helps

Besides of ST Discovery boards, you may want to consider Riverdi displays based on STM32H7. They have various display sizes and touch capabilities.

I think there are also some other companies with STM32-BASE display products like Riverdi 

eg, https://www.lcdlcm.com/application/stm32-tft 

 

Although Riverdi do seem to get the most coverage here.

They are an ST Partner:
