Elixir Ale Versions Save

Backwards incompatible changes

This release cleans up the naming of every module. All modules are now in the ElixirALE namespace and capitalized since they are acronyms. For example, if you were using the I2c module, it's now ElixirALE.I2C. You may want to alias ElixirALE.I2C in your programs to save typing.

• Bug fixes
  • Clean up warnings especially the Elixir 1.4 bare function ones

• Bug fixes
  • I2C transfers may now be up to 512 bytes. Thanks to bendiken for this fix. See https://github.com/fhunleth/elixir_ale/pull/21.

• New features
  • true and false can now be passed to Gpio.write/2
• Bug fixes
  • Include i2c-dev.h to avoid incompatible version on Raspbian 8. This also avoids errors on systems that don't have the header file for whatever reason.
  • Include asm/ioctl.h for a MIPS platform that doesn't include it automatically.

• Force version of elixir_make to workaround OTP 19 ports issue

• Use elixir_make instead of custom mix task

• Bug fixes
  • Fixed race condition when calling Gpio.read/1 with interrupts enabled

• New features
  • Add I2c.detect_devices/1 to scan the I2C bus
  • Add I2c.read_device/3, etc. to support devices on more than one I2C address without needing to create multiple I2c servers

• Bug fixes
  • Previous fix for priv directory in v0.4.0 was insufficient. This release has what is believe to be the correct fix.

• New features
  • Use I2C RDWR ioctl so that write/read combinations are atomic. See I2c.write_read/3.
