Full Control

Independence from open source or any other third-party software results in full control over license clearing

Px-One

The Px-One is based on an STM32H5 microcontroller, driven directly through PennyPixel's patented display-driving technology. You can build a high-resolution, colorful GUI for cost-sensitive applications such as industrial HMIs, thermostats and home energy meters.

Frequently Asked Questions

Find answers to common questions about Embedded Wizard and PennyPixel.

PennyPixel is a patented, firmware-driven method that lets a standard microcontroller drive a high-resolution active-matrix TFT panel directly. What does not change is how you design the GUI; you work with Embedded Wizard exactly as you would for any other target.
Embedded Wizard is the preferred GUI solution for PennyPixel-based displays. The Platform Package, the graphics engine and the runtime environment are all adapted to the PennyPixel architecture, so the GUI runs without a display controller and without external graphics memory.
To evaluate, no. An evaluation kit arrives with a PennyPixel-driven panel and a pre-installed Embedded Wizard demo, and Embedded Wizard is free to download, so one hardware purchase is all you need to get started. For production, the display-driving technology is licensed from Penny Pixel Inc., and the Embedded Wizard commercial license comes from TARA Systems.
PennyPixel itself runs on a broad range of MCU families. The validated Embedded Wizard Platform Package is currently available for STM32.
No. Embedded Wizard renders in software on this platform, so no GPU, no 2D accelerator and no external graphics memory are required.
Yes. Embedded Wizard GUI projects are hardware-independent. The same project can be built for a different target by switching the Platform Package.
Order an evaluation kit and download Embedded Wizard Studio and the right Build Environment free of charge to build your own screens on it.
