1.0.2

Fix of issue 3

_LED class added to avoid conflict with compiling MightyCore. The class name LED conflicts with a global variable. To avoid this, a class derived from LED to let have different name.
The usage of _LED class is just same as LED.
Sample code is available in examples/concept_examples/abstracting_LEDs_in_MightyCore.

Adapting to I2C_device 0.4.0 feature

I2C_device library release 0.4.0 have a feature of selecting TwoWire instance other than Wire.

From this release, this library can access to the temperature sensor devices on different I²C bus.

To use Wire instance, the interface kept compatibility to previous version. To make an instance of the device, it can be declared like..

#include <PCA9955B.h>
PCA9955B ledd;

#include <PCA9955B.h>
PCA9955B ledd( 0x5F );  // I²C target address is 0x5F

If the device is connected on different I²C bus, it needs to use different TwoWire instance.
In such case, use this new feature :)

#include < PCA9955B.h.h>
PCA9955B.h ledd( Wire1, 0x5F );  // Choosing Wire1 and I²C target address is 0x5F

void setup() {
  Wire1.begin();  // Needs to call "begin()" in Wire1
  ..

0.4.0

• Gradation control supported
• For PCA9957, register access issue fixed

0.3.0

added device name header files
