About `nrf51-hal`
Hardware Abstraction Layer (HAL) for the Nordic nRF51 series microcontrollers, written in Rust. Provides safe, Rust-idiomatic access to peripherals such as GPIO, UART, SPI, I2C, timers, and more, implementing the embedded-hal traits for portability.
Key Features
Peripheral access via embedded-hal traits
GPIO control
Serial communication (UART)
SPI and I2C interfaces
Timer and PWM support
Pros & Cons
