baredrv

Lightweight, platform-independent drivers for embedded peripherals. Designed to work on any microcontroller without vendor lock-in. Each driver lives on its own branch - clone only what you need.

Drivers

Driver	Device	Protocol	Description
bh1750	BH1750FVI	I2C	Ambient light sensor
sht3x	SHT30/31/35	I2C	Temperature & humidity sensor
scd4x	SCD40/41	I2C	CO₂, temperature & humidity sensor
sps30	SPS30	UART/I2C	PM1.0, PM2.5, PM4.0, PM10
ze07	ZE07	UART	CO
sx127x	SX1276/7/8/9	SPI	LoRa communication

Clone:

git clone --branch bh1750 --single-branch https://github.com/hphuc15/baredrv bh1750
git clone --branch sht3x  --single-branch https://github.com/hphuc15/baredrv sht3x
git clone --branch scd4x  --single-branch https://github.com/hphuc15/baredrv scd4x
git clone --branch sps30  --single-branch https://github.com/hphuc15/baredrv sps30
git clone --branch ze07   --single-branch https://github.com/hphuc15/baredrv ze07
git clone --branch sx127x --single-branch https://github.com/hphuc15/baredrv sx127x

Need multiple drivers? Just repeat the command for each one into the same folder:

mkdir sensors && cd sensors
git clone --branch sht3x --single-branch https://github.com/hphuc15/baredrv sht3x
git clone --branch scd4x --single-branch https://github.com/hphuc15/baredrv scd4x
git clone --branch ze07  --single-branch https://github.com/hphuc15/baredrv ze07

Design Philosophy

Each driver:

• Has no dependency on any HAL or SDK
• Uses function pointers for I2C/SPI/UART abstraction
• Is fully standalone and portable
• Brings its own platform layer per target

Usage

1. Clone the branch for the driver you need
2. Implement the platform layer
3. Initialize and use

See each driver's README for detailed instructions.

Notes

• Drivers are independent → safe to use individually
• No shared core or hidden dependencies
• Suitable for bare-metal, RTOS, or any embedded platform
• main only contains this README - actual driver code lives on each driver's branch
