STM32H7B3I-EVAL: Need demo codes, Wi-Fi support; Ubuntu 24.04

[vijayajangam]

Hello STM Community,

I am a beginner working with the STM32H7B3I-EVAL evaluation board based on the STM32H7B3LIH6Q MCU, and I am currently setting up my development environment on Ubuntu 24.04.3 LTS.

I installed STM32CubeIDE 1.18.0 using the following installer:

st-stm32cubeide_1.18.0_24413_20250227_1633_amd64.sh.zip

I am facing a few issues and would really appreciate your guidance.

1. Need existing demo codes for STM32H7B3I-EVAL

I would like to get the existing/demo example codes available for this board, especially the examples related to the firmware version currently flashed on my board, which shows:

Firmware Version: V1.0.1

Could anyone please guide me on where to find the exact demo code corresponding to the factory-flashed board behavior, if available?

I am specifically looking for separate demo examples for:

• LED

• ADC

• GPIO

• UART

• SPI

• I2C

• TFT/LCD

• Touch

• Camera

• Wi-Fi

• other onboard peripherals

I am using Linux Ubuntu 24.04.3 LTS, so Linux-compatible steps would be very helpful.

At the moment, I mainly need:

1. official demo/example codes for STM32H7B3I-EVAL

2. factory demo source code / equivalent example

3. camera test example

4. Wi-Fi connection troubleshooting guidance

Any links to official STM32CubeH7 packages, board example folders, or application notes would be greatly appreciated.

Thank you very much.

Do you have any experience with other STM32s? Or other microcontrollers? Or programming in general?

See this post for some 'getting started' tips.

And this one for some basic first steps.

Any particular reason for choosing such an old version ?

Latest is v2.1.0: STM32CubeIDE 2.1.0 released.

Note that this no longer integrates CubeMX: STM32CubeIDE 2.0.0 New workflow tutorial.

You should be able to find existing examples, etc, in CubeMX.

Hello @vijayajangam;

I recommend you to look at STM32H7B3I-EVAL board examples in the STM32CubeH7 

For LED, Camera, LCD and Touch tests, I advise you to run BSP example.

I hope this help you.

Thank you.

Hello ST Team,

I am using the STM32H7B3I-EVAL board. I checked STM32CubeH7 (GitHub + full package), but I could not find clear Wi-Fi example projects for this board.

Since the board supports camera (DCMI) and Wi-Fi, I need help with the following:

1. Any official Wi-Fi demo project for STM32H7B3I-EVAL
2. Any camera demo project for testing LCD preview
3. Availability of prebuilt binaries (.hex / .bin / .elf) for quick hardware testing
4. Exact project paths in STM32CubeH7 package (if available)

Goal: quick validation of camera + Wi-Fi hardware

Please share any working example or reference.

Thank you

Hello @vijayajangam ;

There is an example of use of WiFi on STM32H7B3I-EVAL in STM32CubeH7 firmware package in Projects\STM32H7B3I-EVAL\Demonstrations\ClockAndWeather

So, I recommend you to look at BSP and ClockAndWeather examples and get inspired to configure your project.

Thank you.
