rpi_gpio 0.8.1

rpi_gpio is a Dart library for accessing the Raspberry Pi GPIO pins.

Changelog

0.8.1

• add platforms to pubspec indicating only Linux is supported

0.8.0

• convert code to use dart:ffi
• add GpioInput.allValues

0.7.2

• another native build script fix for Windows

0.7.1

• minor pubspec.yaml updates for better null-safety
• minor build cleanup
• make native build script more lenient

0.7.0

• migrate to null safety
• update build script to work on Windows

0.6.0

• rename build_lib to build_native
• move all native operations to separate isolate so that PWM and polling continue to work regardless of whether the main isolate is blocked (e.g. dart:io sleep)
• BREAKING: RpiGpio requires async init to spin up isolate
• BREAKING: GpioInput.value returns Future<bool>
• RpiGpio.dispose returns a Future that completes when cleanup is complete
• loosen SDK requirements to allow execution on older Rasberry Pi models

0.5.1-dev.1

• add GpioPwm pin for software based PWM
• update SDK requirement to 2.8.4
• update dependencies
• code style cleanup

0.5.0

• BREAKING: automatically allocate I2C, SPI, and EEPROM pins unless flag in RpiGpio constructor is set to false
• consolidate all examples into single example.dart with debouncer
• add example_test.dart with mock gpio
• add Gpio dispose for cleaning up native resources
• code cleanup

0.4.0-dev.1

• BREAKING CHANGES rework and simplify API
• Upgrade for pre-2.0 and fix analyzer issues
• Format dart code using dartfmt

• Changed Gpio.hardware= to Pin.gpio=
• Added optional RpiGPIO.description method
• Added Mode.other to match fletch gpio package
• Added abstract GPIO class to match fletch gpio package

0.2.2

• Update wiringPi native code for Pi v2
• Add top level pin function and deprecated Gpio.pin method
• Add gpioNum method to return GPIO number for pin
