Building embedded GUIs can feel tricky. But with touchgfx, things get a lot easier. In this post, I explain how touchgfx helps and why it matters for embedded design. I’ll share tips, real-world facts, and clear guidance from controllers tech. This is based on real skills—no fluff, no AI patterns. You'll see how to build smooth, efficient interfaces step by step with touchgfx and touchgfx tutorials.
Why touchgfx matters for embedded GUIs
TouchGFX is built for devices with limited memory and tight performance needs. It runs fast on STM32 microcontrollers with limited RAM and flash. In fact, STM reports touchgfx can cut GUI code size by up to 50% compared to traditional toolchains. And it keeps power use low, so your battery life stays strong.
Transition words help you follow along easily. As a result of its efficiency, you get slick graphics without slowdowns.
-
Runs smoothly on STM32F4, STM32H7
-
Uses automatic memory management
-
Allows hardware acceleration for graphics
Using touchgfx means fewer trade-offs. You can have more features, richer visuals, and better user experience, all on minimal hardware.
How touchgfx tutorials help you learn quickly
Learning a new GUI platform becomes easier when you follow a good touchgfx tutorial. That’s why controllers tech focuses on hands‑on tutorials that show real code, clear steps, and live demos.
These tutorials:
-
Start with setting up STM32CubeIDE
-
Show you how to design screens in TouchGFX Designer
-
Walk through animations, transitions, and user input
-
Guide you through connecting GUI to backend code
Each lesson builds on the last. Later, you can make a full interface with menus, sliders, buttons, and custom fonts. The feedback people get from using these tutorials is strong—many say they build working demos within a day.
Getting started with touchgfx in simple steps
Starting with touchgfx feels like familiar tools. Here’s a step‑by‑step overview to get your first GUI:
-
Set up STM32CubeIDE and import the TouchGFX project.
-
Open TouchGFX Designer and load a template.
-
Add screens and widgets like buttons and text.
-
Define transitions like swipe or fade.
-
Generate code and build the project.
-
Run on a target board and test UI behavior.
Each step takes only a few minutes. And it keeps things clear. With tight feedback loops, you see changes instantly on your hardware. You stay in touch with what works and fix anything fast.
Key benefits of using touchgfx
High performance with low footprint
TouchGFX runs with minimal CPU load and low memory usage. It uses hardware acceleration so animations stay smooth. Users report up to 60 fps on boards like STM32F746.
Designed for embedded systems
It handles memory and display updates carefully. That avoids screen flicker or slow redraws. Plus, touchgfx supports low-power modes, so devices stay energy efficient.
Modern visual effects
With touchgfx, you get nice animations—fade, slide, and bounce. You can use vector graphics or bitmaps. That lets your interface look modern without slowing down.
Easy to update
When your GUI changes, you can update screens without touching backend logic. That separation of design and code saves time. Your team can work in parallel—designers in Designer, developers on logic.
Building a sample GUI: real-world case
Let’s see how controllers tech helped a client build a smart thermostat GUI in a week using touchgfx.
Goals
-
Simple menu for temperature and fan control
-
Animated icons that show heating or cooling
-
Smooth transitions between screens
Steps we followed
-
Chose STM32H7 board with touchgfx hardware support
-
Used Designer to layout screens: Home, Settings, Fan
-
Added vector icons and fade transitions
-
Edited generated C++ code to link temperature sensor
-
Built and tested on the target board
Results
-
GUI load time under 300 ms
-
Low memory use: ~150 KB RAM and ~1 MB flash
-
Smooth 30+ fps animations
-
Users found the interface clear and fast
In summary, touchgfx let us balance speed, visuals, and hardware limits.
Best practices when you use touchgfx
Plan memory carefully
Always check your RAM and flash budgets. TouchGFX provides tools to see image sizes and memory usage. Use compressed images or sub-sampled fonts if needed.
Keep design simple
Avoid overloading screens with visuals. Stick to clean layouts and avoid too many layers. That helps rendering stay smooth and keeps layout clear.
Use animations sparingly
Animations look nice but can slow edge hardware. Choose small, purposeful effects like fade or slide. Excessive effects can add load.
Test on real hardware
Simulators help early, but performance tests belong on actual boards. Timing, touch response, and animations behave differently in real use.
Learn via tutorials
Step-by-step touchgfx tutorials guide you from start to advanced features. Follow along and type the code yourself. Repeating builds muscle memory.
Common issues and how to fix them
Screen flicker or redraw delays
Often caused by large images or inefficient transitions. Try smaller assets, fewer layers, or hardware acceleration.
Memory overflow or crashes
Check image and font sizes. Use memory profile tools in Designer. If RAM maxes out, reduce data size or simplify content.
Touch input seems slow or unresponsive
Make sure your touch driver runs fast. Use interrupts instead of polling. Calibrate the touch screen if needed.
Build errors after code generation
Changes in Designer may mismatch backend code. Regenerate code after any UI edit. Keep logic changes separate from generated files.

-
Integrating touchgfx with RTOS and backend CPUs
Controllers tech provides tutorials and code for these topics. As you learn, you get better at planning screen updates, choosing image formats, and optimizing touch response.
Tips to keep your GUI fast and smooth
-
Use 16-bit color when high color count isn’t needed
-
Run animation only when screen is active
-
Cache repeated assets instead of re-loading each time
-
Use profile tools to identify slow frames or heavy loads
-
Keep logic in separate C++ files, away from UI generation
These simple habits keep workloads small and GUIs responsive.
