## [0.1.9] - 2017-02-27
|
|
- fix warning about return in readButton8()
|

|
|
- Merged work of Septillion
|
|
- Fix/refactor ButtonRead8() - see https://github.com/RobTillaart/Arduino/issues/38

|
|
|
|
## [0.1.07] - 2016-05-02
|
|
- (manually merged) Septillion
|
|
- added dataOut so a write() doesn't read first,
|
|
possibly corrupting a input pin;
|
|
- fixed shift comment, should read 1..7;
|
|
- added begin() to be sure it's in a known state,
|
|
states could be different if uC is reset and the PCF8574 isn't;
|
|
- added buttonRead() and buttonRead8()
|
|
which only effect the output while reading
|
|
|
|

|
|
- (intermediate) added defined errors + refactor rotate
|
|
|
|
## [0.1.05] - 2016-04-30
|
|
- refactor, +toggleMask, +rotLeft, +rotRight
|
|
|
|
## [0.1.04] - 2015-05-09
|
|
- removed ambiguity in read8()
|
|
|
|
## [0.1.03] - 2015-03-02
|
|
- address int -> uint8_t
|
|
|
|
## [0.1.02] - ?
|
|
- replaced integers with uint8_t to reduce footprint;
|
|
- added default value for shiftLeft() and shiftRight()
|
|
- renamed status() to lastError();
|
|
|
|
## [0.1.01] - ?
|
|
- added value(); returns last read 8 bit value (cached);
|
|
value() does not always reflect the latest state of the pins!
|
|
|
|
## [0.1.00] - 2013-02-02
|
|
- initial version
