ull-drivers-rs

Personal collection of no_std embedded drivers under the ull-* naming scheme.

The point is simple: keep drivers I understand, can use on hardware, and can change without fighting layers I do not need. The main path should be practical and clear, with lower-level escape hatches when experimenting with device behavior makes sense.

Goals

• first-party drivers I fully understand and maintain
• no_std by default
• embedded-hal 1.0 compatibility
• one crate per device family
• practical examples and tests
• no shared crate until multiple drivers actually need one

Crates

• drivers/ull-sht3x: embedded-hal 1.0 I2C driver for Sensirion SHT3x-DIS humidity and temperature sensors.
• drivers/ull-ssd1306: embedded-hal 1.0 SSD1306 display driver with optional embedded-graphics-core support.

Notes

• This workspace currently keeps shared code inside each driver until multiple crates expose a real common layer.
• Driver style is documented in docs/driver-style.md; use it as the source of truth for new ull-* drivers.
• Workspace-wide settings currently centralize edition, license, and repository metadata.
• Workspace-wide Rust linting forbids unsafe code.
