Graphic application demonstration solution based on STM32F4/F7

Recently, ST Company held the first STM32 Summit in Shenzhen with the theme of “Eco-Cooperative Innovation”. On the agenda, ST gave a comprehensive introduction to STM32's future-oriented product strategy and market planning for the participants. ST official and its partners showed various STM32-based products and application solutions, software and hardware development tool platforms. The summit featured more than 30 partner booths to showcase their STM32-based development ecosystem tools or innovative product applications. In addition, ST also arranged a technical seminar based on STM32 applications.

Here, I will list some STM32F4/F7-based graphics application demonstrations presented at this summit, so that people who pay attention to this section have an understanding of the STM32F4/F7-based graphics solution application, which is considered to be a joke. These graphic presentation programs are designed based on the official ST learning board. The relevant learning board information can be downloaded from the official website.

Introduction to several graphic schemes based on STM32F4/F7 learning board

1. STM32F769 graphics capability and network function demonstration

This demonstration is based on the STM32F7 high performance family of microcontroller evaluation boards, demonstrating the superior graphics processing power of the STM32F7 chip. The new STM32F76X series supports JPEG hardware codec and can play MoTIon JPEG format video, which can be output to 800*480 screen through MIPI interface. Its powerful network capabilities enable Ethernet-based VNC clients.

The program can be applied to human-machine interface occasions such as smart home and industrial control.

2, STM32F746 virtual 3D graphics demonstration

Run the TouchGFX graphics engine on the STM32F746 development kit, combined with the STM32's built-in CHROM ART graphics accelerator for transparency and analog 3D animation. Directly drive a 480*272 4.3” TFT screen.

The solution can bring smooth transition and 3D dynamic stereo switching effect to the 2D graphical interface.

3, STM32F746 WIN10 style industrial control interface demonstration

Using the graphics library provided by the Embedded Wizard, you can create a Win10-like user interface with only a small amount of resources on the chip, directly driving the onboard 480*272 4.3” TFT screen.

The solution can be applied to simple and straightforward graphical human-machine interface scenarios, such as smart watches and other control devices.

4, STM32F746 multi-graphics function demonstration

Run the TouchGFX graphics engine on the STM32F746 development board, combined with the STM32's built-in CHROM ART graphics accelerator for multi-graphics, versatile and transparent animations, and directly drive the 480*272 4.3” TFT screen.

The program can also be applied to human-machine interface applications such as smart home and industrial control.

5, STM32F469 sports step application graphics program

Using the graphics library provided by the Embedded Wizard, the user interface for sports watches is designed on the STM32F469 for secondary development. The interface can finally be displayed on the 800*480 TFT screen through the MIPI interface.

6, STemWin graphics solution based on STM32F429 exploration kit

Using ST's free STemWin GUI to develop a basic human-machine graphical interface on the STM32F429 Discovery Kit, and directly drive the QVGA screen, it has the characteristics of low resource consumption and low power consumption.

This solution is very suitable for smart wearable products.

7. TouchGFX graphics solution based on STM32F429 exploration kit

Using the TouchGFX GUI provided by DRAUPNER to develop a basic human-machine graphical interface on the STM32F429 Discovery Kit, combined with the STM32's built-in CHROM ART graphics accelerator, reducing CPU load and improving the computational processing power of the MCU. The solution is suitable for smart wearable products and other human-computer interaction situations where image quality is high.

Outdoor Fan

24-hour long battery life, low power consumption and high wind power are better manifestations, whether it is shopping, traveling, going to school, commuting, watching dramas, or working, it will be your intimate partner. The fan blade is designed with soft silicone, which can be automatically stopped when touched, and the protection is more comprehensive.
