Expand description

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 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, 5, CM, CM 3, CM 3+, CM 4, 400, Zero, Zero W and Zero 2 W. Backwards compatibility for minor revisions isn’t guaranteed until v1.
