Arduino Hardware I2C for AVR (plain c) 2017-2018 SMFSW

  • cI2C is set to work on AVR targets only -> for other targets, you may use WireWrapper instead (will be using Wire) -> cI2C & WireWrapper libs declare same structures & functions as seen from the outside (switch between libs without changing anything but the include)

Feel free to share your thoughts @ xgarmanboziax@gmail.com about: - issues encountered - optimizations - improvements & new functionalities

** Actual: v1.3 13 May 2018:

  • Delay between retries is now 1ms
  • Adding support for unit tests and doxygen documentation generation with Travis CI
  • Updated README.md

v1.2 30 Nov 2017:

  • No internal address transmission when reading/writing to next internal address (make sure not to r/w last 16 address right just after init, otherwise make a dummy of address 0 just before)

v1.1 29 Nov 2017:

  • Frequency calculation fix (thanks to TonyWilk)
  • Set Frequency higher than Fast Mode (400KHz) will set bus to Fast Mode (frequency is up to 400KHz on AVR)
  • I2C_set_xxx now returns values applied, not bool

v1.0 21 Nov 2017:

  • Added const qualifier for function parameters
  • Return from comm functions if bytes to R/W set to 0

v0.6 12 Jul 2017:

  • compliance with Arduino v1.5+ IDE source located in src subfolder

v0.5 31 Jan 2017:

  • refactored I2C_SPEED enum names for coherence with I2C specifications
  • High Speed mode added in I2C_SPEED enum

v0.4 23 Jan 2017:

  • less inlines (less warnings)
  • inlines put into header (compatibility with WireWrapper)
  • other common code between cI2C and WireWrapper changes
  • README.md updated to tell about WireWrapper library

v0.3 22 Jan 2017:

  • used function pointer in function parameters for convenience
  • fixed read bug for devices without register address
  • refactored rw booleans with enum instead (implied logic change)
  • I2C_sndAddr function parameters changed
  • added I2C_uninit function to release i2c bus
  • refactoring & optimisations
  • doxygen pass without warnings/errors now
  • examples updated to test more of the library

v0.2 16 Jan 2017:

  • First release
