Embedded Digital Image Processing with Microcontrollers: STM32 Examples

Source repository: https://github.com/embeddip/examples-stm32

This repository contains STM32 examples and support files for the book Embedded Digital Image Processing with Microcontrollers. The project targets STM32F746-based development with STM32CubeMX-generated support files, CMake, and the GNU Arm Embedded toolchain.

Contents

• Core/: STM32 application source and headers.
• Drivers/: STM32 HAL, CMSIS, CMSIS-DSP, and CMSIS-NN files.
• Middlewares/: third-party middleware used by selected examples.
• LIBJPEG/: JPEG support files.
• embedDIP/: local copy of the embedded digital image processing library.
• apps/: listing applications that can be built by replacing Core/Src/main.c.
• build_all_apps.sh: script for compiling the listing applications.
• CMakePresets.json: CMake presets for Debug, Release, RelWithDebInfo, and MinSizeRel builds.

Requirements

• CMake 3.22 or newer
• Ninja
• GNU Arm Embedded toolchain with arm-none-eabi-gcc
• STM32CubeMX or STM32 VS Code tooling for project regeneration or board-specific changes
• STM32F746 target board, such as STM32F746G-DISCO

Build

Configure the Debug build:

cmake --preset Debug

Build the Debug configuration:

cmake --build build/Debug

Other available presets are Release, RelWithDebInfo, and MinSizeRel.

Build All Listing Applications

Build every file in apps/:

./build_all_apps.sh

The script copies each listing application into Core/Src/main.c, builds it, saves the generated artifacts, and restores the original main.c. Build logs and generated artifacts are written under apps/build_outputs/.

Branches

The STM32 examples are organized across branches:

Branch	Contents
main	Default STM32F746 project branch.
main-c-apps	C listing applications.
main-cpp-apps	C++ listing applications.
main-c-ai-apps	C AI listing applications.
main-cpp-ai-apps	C++ AI listing applications.
