Crate rppal[][src]

RPPAL provides access to the Raspberry Pi’s GPIO, I2C, PWM, SPI and UART peripherals through a user-friendly interface. In addition to peripheral access, RPPAL also offers support for USB to serial adapters. The library can be used in conjunction with a variety of platform-agnostic drivers through its embedded-hal trait implementations.

RPPAL requires Raspberry Pi OS or any similar, recent, Linux distribution. Both gnu and musl libc targets are supported. RPPAL is compatible with the Raspberry Pi A, A+, B, B+, 2B, 3A+, 3B, 3B+, 4B, CM, CM 3, CM 3+, CM 4, 400, Zero and Zero W. Backwards compatibility for minor revisions isn’t guaranteed until v1.0.0.
