Raymon-Lib-STM32 is a collection of embedded C/C++ utilities, peripheral examples, and experiments for STM32 microcontrollers. The repository is organized by feature rather than as a single installable package. Each component may have its own hardware, STM32 HAL, compiler, or library requirements.
| Component | Purpose | Requirements / notes |
|---|---|---|
| QBuffer | Fixed-capacity byte buffer, packet framing, CRC and command parsing | Header-only C++; review API and buffer limits |
| QPacket | Packet framing with markers, length, counter and CRC | Uses QCRC; inspect QCommand too |
| FlashEEPROM | Store and restore a structure in internal flash | STM32 HAL and project main.h; target flash layout must be checked |
| PrintfUart | Formatted UART input/output | STM32 HAL and project main.h |
| Servo Motor SG90 | PWM-based servo example | Existing guide uses STM32F1/TIM2 as its example |
| FFT for STM32H743 | FFT example using CMSIS-DSP | Compatible CMSIS-DSP and target configuration |
| Bootloader jump | MCU-specific bootloader jump | Verify exact MCU and memory map; potentially unsafe |
| Lock program in code | Read-protection / firmware-locking notes | Potentially destructive; review before use |
| Bluetooth example | Module-specific Bluetooth code | Hardware and protocol dependent |
| PW05 Bluetooth | UART-based Bluetooth module control | Firmware, AT commands and GPIO wiring dependent |
| ILI9488 TFT | SPI TFT display and drawing APIs | Multiple conflicting variants; select and validate one only |
| cUart | C++ streams backed by UART | Blocking UART streams; read limitations before use |
| C/C++ rename helpers | Rename main.c / main.cpp | Renames only; does not convert source code |
This catalogue is based on files currently present in the repository. It does not claim that every component has been compiled or hardware-validated.
- Clone the repository.
- Open the folder for the component you need and read its local README.
- Start from an STM32CubeIDE / STM32CubeMX project configured for the exact MCU, clock tree, pins and peripherals.
- Add only the required files and configure include paths, STM32 HAL, and external dependencies.
- Build for the target and test on hardware with a safe recovery procedure.
git clone https://github.com/Raymon-Research-Team/Raymon-Lib-STM32.gitThere is no verified repository-wide build system or single installation command documented here. Components must be integrated individually.
- Internal flash: FlashEEPROM erases a calculated flash region before writing. Verify the reference manual, erase granularity, banks, reserved pages, and linker map before use.
- Bootloader / read protection: Incorrect addresses or protection settings can make firmware inaccessible or require a full-chip erase.
- PWM / servo: Timer period, prescaler, channel, and GPIO settings depend on the MCU and clock tree.
- FFT: CMSIS-DSP version, compiler settings, memory placement, and FPU configuration affect integration.
- No blanket compatibility guarantee: Source presence does not establish support for every STM32 family or board.
Include the MCU part number, board, toolchain version, HAL/CMSIS versions, build output, and reproducible steps in bug reports. Do not describe a component as hardware-validated unless it was tested on the specified target.
