AFCI offline kit - Part 1: STM32F4 firmware & embedded libraries
Offline development kit for an arc-fault detection / electrical-fire prevention system (current sensor -> STM32F407 ADC+DMA -> FFT/STFT features -> quantized DNN -> trip). Target offline PC: Windows 10/11 x64, CPU-only Python training.

01_STM32CubeF4/ |
STM32CubeF4 full MCU package (GitHub STMicroelectronics/STM32CubeF4, all submodules): HAL + LL drivers, CMSIS Core/Device, BSPs, middleware (FreeRTOS, USB, FatFs, LwIP), and hundreds of example projects for F4 boards (incl. STM32F4-Discovery / STM32F407). Also contains the HAL user manual (.chm) under Drivers/STM32F4xx_HAL_Driver/. |
Base firmware for the STM32F407: ADC + DMA + TIM examples (Projects/STM32F4-Discovery/Examples/ADC, .../DMA, .../TIM). Point STM32CubeMX/CubeIDE at this zip via Help > Manage embedded software packages > From Local (note: CubeMX may still prefer the ST-packaged en.stm32cubef4_v1-xx-x.zip, see the checklist in Part 7). |
BSD-3 / Apache-2.0 / ST SLA0044 (per component) |
02_CMSIS/ |
CMSIS_6 (Core), CMSIS-DSP (FFT, FIR/IIR, matrix, statistics, windowing, optimized for Cortex-M4 DSP/FPU), CMSIS-NN (int8 NN kernels), CMSIS_5 (legacy; same generation as the CMSIS copy inside CubeF4). | ADC window -> filter -> FFT -> features on the F407; fast int8 inference. | Apache-2.0 |
03_TinyML_runtime/ |
TensorFlow Lite for Microcontrollers source (tflite-micro). |
Alternative to ST Edge AI / X-CUBE-AI runtime: run a quantized .tflite model on the F407 with CMSIS-NN kernels. |
Apache-2.0 |
04_Docs_HTML/ |
Built HTML documentation for CMSIS 6 (v6.4.0), CMSIS-DSP (v1.18.0), CMSIS-NN (v8.0.0). Open index.html. |
API reference offline. | Apache-2.0 |
05_RTOS/ |
FreeRTOS-Kernel (latest). CubeF4 also ships its own FreeRTOS copy under Middlewares/Third_Party. |
Later stage (tasks: acquisition / DSP / inference / safety / logging). | MIT |
All archives are standard .zip (open with Windows Explorer or 7-Zip). Git history was removed to save space.
Rebuilding split files
Files over 100 MB were split into *.part001, *.part002, ... pieces. After downloading the whole repo:
- Windows:
powershell -ExecutionPolicy Bypass -File .\join_parts.ps1 - Linux/macOS:
bash join_parts.sh
Both scripts rebuild the files and check them against SHA256SUMS.txt.
