gpio-manager 1.1.3

Rust bindings for the rppal crate to manage GPIO pins on a Raspberry Pi.

Description

• These are rust binding around the RPPAL - Raspberry Pi Peripheral Access Library crate that gives access to gpio, pwm, spi, and more. As of current, the only provided bindings are for the gpio library. Support for the other functions may come later on.
• These bindings allow you to call the rust code from python in a way that looks like any other python object

Features

• Able to make multiple objects that can call the gpio without generating errors
• Support for event driven io using callbacks
• Supports software pwm
• Allows for setting up pins as input or output
• Works with multiple platforms

Usage

• To use you need to first create a GPIOManager object, this can be done by calling manager = gpio_manager.GPIOManager().
• To set up a pin as input with the pull-up resistor enabled on the pin manager.add_input_pin(BUTTON_PIN, gpio_manager.IPinState.PULLUP).
• To set up a pin as output run manager.add_output_pin(LED_PIN).
• To set an output pin to the low state run manager.set_output_pin(LED_PIN, gpio_manager.OPinState.LOW).
• To assign a callback to an input pin manager.assign_callback(BUTTON_PIN, gpio_manager.TriggerEdge.FALLING, button_callback).
• To wait on an input pin to trigger an edge manager.wait_for_edge(BUTTON_PIN, gpio_manager.TriggerEdge.FALLING).
• To set pwm on an output pin run manager.set_pwm(PWM_PIN, PERIOD_MS, PULSE_WIDTH_US).
• To reset a pin to its default state run manager.reset_pin(PIN).
• To set all outputs to low and clear all interrupts run manager.cleanup().

Warranty

• This library is provided as is and is not guaranteed to work in all cases.

Support

• If you have any issues with the library please contact me in class or via the discussion board on brightspace.

Coming Soon

• Support for UART
• support for SPI
• Support for hardware PWM
• Support for I2C
• Documentation on readthedocs.io
