Elixir Ale Versions Save

• Bug fixes
  • Fixed incorrect edge notifications when registering for only rising or falling interrupts. Thanks to jsimmons2 for this fix.

• New features

  • Add GPIO.pin/1 to get the pin number back. Thanks to @jjcarstens
  • Add child_specs/1 to support creating GPIOs in supervisors

• Improvements

  • Various spec improvements

This release will work with Elixir 1.7. Support for Elixir versions before 1.6 has been dropped.

• Improvements
  • Add :start_value to initialize a GPIO. Thanks to @jjcarstens for this feature.

• Bug fixes
  • Remove catchall receive handlers that would capture GenServer.call messages when functions were called by multiple threads
  • Timeout all port calls just in case. This hasn't been observed to my knowledge, but seems like a sensable precaution. The timeout is absurdly long (500 ms) so it shouldn't trigger.
  • Pass errors detected by C code to Elixir rather than crashing

• Bug fixes

  • Fix memory overrun when using large I2C transfers. This only affected a few devices since most devices maxed out at much smaller sizes. Also add compile-time check to prevent this from happening again.

• Improvements

  • Increase max SPI transfer size to 4096. This aligns it with py-spidev and enables communication with the Unicorn Hat HD.

• Bug fixes

  • Fixed typespec for set_int/2. Thanks to tmecklem for catching the ommission.

• Improvements

  • Various documentation and code formatting updates

• No changes since v0.7.0.

• New features
  • Added and improved helper functions for finding I2C devices and I2C and SPI buses.

• Bug fixes
  • Fix message buffer size that was too small for really large I2C transfers
  • Many documentation improvements from Axel Clark.

• Bug fixes
  • Enlarge I2C buffer size to support some OLED displays
  • Support compilation on non-Linux platforms. It won't work, but this makes it possible to have unconditional deps on elixir_ale in multiplatform projects.
