## [0.2.0] - 2023-07-17
|
||||
- refactor interface (breaking)
|
||||
- for compatibility with PCA9552, PCA9551
|
||||
- add **uint8_t getAddress()**
|
||||
- add **void digitalWrite(led, value)**
|
||||
- add **uint8_t digitalRead(led)**
|
||||
- add **reset()**
|
||||
- rename setLEDSource to **setOutputMode()**
|
||||
- rename channelCount to **outputCount()**
|
||||
- add #defines for modi
|
||||
- add some error handling
|
||||
- add examples
|
||||
- update readme.md
|
||||
- internal refactor

#### Power On Reset

The PCA9553 will keep its settings as long as it is powered on.
|

This means it can start with an previous configuration when uploading
|

two different sketches short after each other.
|

|

To handle this the library has a **reset()** function which sets
|

the device in the Power On state.

## Future
|

|

#### Must
|
||||
|
||||
- improve documentation
|
||||
- test test test
|
||||
- test with hardware
|
||||
|
||||
#### Should
|
||||
|
||||
- **reset()** power on reset...
|
||||
- GPIO modi pins
|
||||
- **pinMode()**
|
||||
- **digitalWrite()**
|
||||
- **digitalRead()**
|
||||
- improve error handling
|
||||
- return values, where etc.
|
||||
- **setLEDSource(src0, src1, src2, src3)** one call
|
||||
- defines for sources
|
||||
- getAddress()
|
||||
- test
|
||||
- reset function
|
||||
|
||||
|
||||
#### Could
|
||||
|
||||
|
||||
#### Wont (on request)
|
||||
|
||||
- no usage of autoincrement register
|
||||
- percent interface for PWM
|
||||
- time interface for prescaler
|
||||
- default setup in begin (what how)
|
||||
- alternative interface calls
|
||||
- **setPWM(pwm0, pwm1)**
|
||||
- **setPrescaler(psc0, psc1)**
|
||||
- **setChannel(channel, psc0, pwm)**
|
||||
- **setPWM(channel, pwm);
|
||||
- **setPrescaler(channel, psc1)**
