About `imxrt-hal`
imxrt-hal is a Rust hardware abstraction layer (HAL) for NXP i.MX RT processors, providing a safe and ergonomic interface for embedded development. It offers drivers that work across multiple i.MX RT chips supported by the imxrt-ral register access layer, with specific examples for boards like the 1010 EVK and Teensy 4. The project is open source under dual Apache-2.0/MIT licenses and is actively maintained with regular releases.
