Crate rppal

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. Both embedded-hal v0.2.7 and v1 are supported.

RPPAL requires a recent release of Raspberry Pi OS. Similar Linux distributions may work, but are unsupported.

Both gnu and musl libc targets are supported. RPPAL is compatible with the Raspberry Pi A, A+, B, B+, 2B, 3A+, 3B, 3B+, 4B, 5, CM, CM 3, CM 3+, CM 4, CM 5, 400, Zero, Zero W and Zero 2 W. Backwards compatibility for minor revisions isn’t guaranteed until v1.
