Rebuilding the STM32 Source Map
I first removed PCB-inspection material from the STM32 track, then regrouped the 22 prototype photos, setup slides, schematics, code, and CubeIDE archive by hardware, configuration, acquisition, filtering, and detection.
What I checked first
I first removed PCB-inspection material from the STM32 track, then regrouped the 22 prototype photos, setup slides, schematics, code, and CubeIDE archive by hardware, configuration, acquisition, filtering, and detection.
Source view
- All 22 photos show the NUCLEO board, breadboard, electrodes, or powered status LEDs in the biosignal prototype.
- The 40-slide deck covers CubeIDE project creation, pin/clock/ADC/USART setup, and CMSIS source/include paths.
- I treat code variants as sources, not separate results, and first checked their shared flow and duplicate SHA-256 values.
Implementation path
Only the saved configuration and processing sequence are shown.

The reviewed sources contain 22 prototype photos, a 40-slide STM setup deck, a three-page KiCad schematic, an ADC/UART note, an HRV module, two PPG code records, twelve top-level ECG C variants, and a complete CubeIDE project archive. I do not count byte-identical variants or ST/Arm vendor files as separate results, and I make no new performance claim without saved measurements.
