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 anyhting but the include)

|
v1.3 3 May 2018:
|
||
|
|
- 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
