0.13

  • Upgrade dependencies, minor bug fixes

0.14

  • Serial devices
  • gpiod character device incorporated
  • Renamed the “sysfs” internal provider to built-in

1.0.0

  • Refactored package hierarchy to clearly distinguish between devices, API and SPI
  • Documentation update - moved from readthedocs to GitHub pages

1.0.1

  • Minor bug fix to support Raspberry Pi 1 Model B
  • Introduce readFully method for serial devices to read specified number of bytes before returning

1.1.0

  • Changed whenPressed / whenReleased to receive epoch time; removed readBlocked, minReadChars and readTimeout from SerialDevice constructors

1.1.1

  • Changed whenPressed / whenReleased to receive nano time rather than epoch time

1.1.2

  • Bugfix release - fixes to GPIO
  • I2C retries

1.1.3

  • Bugfix release - fix for I2C retry logic
  • GPIO event Epoch time is calculated from nano time

1.1.4

  • Bugfix for BME280 humidity reads - config registers need to be written to in the correct order
  • Enhancements to ADS112C04 - support for input multiplexer configuration (differential reads)
  • Renamed util.Event to util.EventLock
  • Preview / sandpit introduction of a new generic FIFO event queue

1.1.5

  • Refactored the way that GPIO devices are provisioned internally - all now use PinInfo rather than a GPIO number
  • DigitalInputDevices allow activeHigh to be overridden
  • Fix for Raspberry Pi Zero W - now loads the correct boarddefs file, rather than the generic Raspberry Pi one
  • Bugix for PwmOutputDevice cleanup

1.1.6

  • Added operation to allow AutoCloseable interfaces to be automatically invoked on shutdown

1.1.7

  • Fixed system-utils-native library for aarch64
  • Added PWM setFrequency operation
  • Detect RPi400 and CM4

1.1.8

  • Shutdown logic moved to DeviceFactoryHelper.shutdown
  • Deprecated WaitableDigitalInputDevice and moved waitable logic up to AbstractDigitalInputDevice
  • New Debounced DigitalInputDevice added to api.sandpit
  • Added Builder to Button
  • Use mmap (if available) when getting / setting GPIO values using built-in sysfs
  • Ensure all nano timestamp values use CLOCK_MONOTONIC rather than CLOCK_REALTIME

1.1.9

  • Tweaks to native library cross compilation
  • #68 bug-fix for I2C on 64-bit systems
  • Fix to SystemInformation coloured output with Jansi on armv6

1.2.0

  • Moved all IMU devices out of diozero-core to diozero-imu-devices to remove dependency on commons-math3 (Quaternion) from diozero-core
  • Removed deprecated methods in DigitalInputDevice and MmapIntBuffer and the deprecated class WaitableDigitalInputDevice
  • Added BoardPinInfo getByPhysicalPin()
  • Added AnalogOutputDevice
  • Switched to non-daemon threads
  • Changed DiozeroScheduler to only create a single (scheduled) thread pool - the cached thread pool was blocking the JVM from terminating for 60 seconds
  • Improvements to DigitalOutputDevice on-off loops
