You can purchase the STM32 Embedded 10.1" display from various sources:
Specification#
Power Supply#
The board supports a wide input voltage range of 6-48V, making it suitable for various industrial applications.
Performance#
The drivers are configured for standard double buffering. This means even if a single pixel changes on the screen, the whole screen is updated.
While music was played, the MCU was running at 100% and reached 20-22 FPS, which is really decent on this high-resolution display.
Frame Rate (FPS)#
The average frame rate was 25 FPS and was mostly above 20 FPS.
Memory#
The 1280 x 800 display is likely one of the largest I've ever seen driven by a standard MCU. Such a large display necessitates a substantial amount of RAM for frame buffers and general rendering. However, the Riverdi STM32 Embedded 10.1" display board rises to the challenge, offering all the power and memory needed to effectively utilize this exceptional display.
In the video, LVGL was operating in 16-bit mode. This setup required 1280 x 800 x 2 bytes = 2MB for a single frame buffer. Given that the driver configuration used three frame buffers, there was still 2MB available in the 8MB external RAM, and the internal RAM was not utilized by the draw buffers or frame buffers at all.
LVGL itself requires approximately 64kB RAM for the widgets (though the actual size varies depending on the specific user interface). Beyond this, the entire 1MB of internal RAM and the remaining 2MB of external RAM are available for the application. Additionally, images or fonts can be loaded into this space from an SD card or external flash.
The 8MB external RAM is also capable of supporting two 32-bit frame buffers. Therefore, with an adjusted driver configuration, by sacrificing some memory, enhanced color depth can also be achieved.
Quality#
Display#
This board comes with an IPS display, so it has amazing viewing angles and brightness too.
Touchpad#
Riverdi's STM32 Embedded 10.1" display can be ordered with an industrial-grade capacitive touch pad or without a touchpad as well.
During our evaluation, the touchpad was very accurate and we haven't found any issues with it.
Robustness#
This board is designed for integration into a final product, even in challenging environments. It features a durable build, a smooth front surface, pre-drilled mounting holes, and reliable connectors.
Development#
To get started with the software part, you can just clone this repository from GitHub and import it into CubeIDE. And that's it. You will find all peripherals pre-configured for you. All you need to do is connect the board and hit the build and flash buttons.
As you are probably used to from ST, you will find a very fast and stable debugger.
Conclusion#
Riverdi's STM32 Embedded 10.1" display stands out as a high-caliber, professional device, tailored for serious industrial applications. Its exceptional quality is evident, aligning perfectly with the standards of a Professional certificate. The display boasts high brightness, excellent visibility, and vibrant colors, all complemented by an industrial-grade touch panel. These features are integrated into a robust and stable construction. At its core, the device is powered by a powerful and contemporary STM32H7 microcontroller unit (MCU).
On the software front, it utilizes ST's renowned and well-established CubeIDE, ensuring reliability and performance. This display is an ideal choice for those seeking a combination of stability and high performance in industrial applications.
