Andriy Makukha / PCAL6416

The PCAL6416A is a low-voltage 16-bit general purpose I/O (GPIO) expander with interrupt. This component library is compatible to basic operation as GPIO expanders: PCAL6416A, PCAL9555, PCA9555, PCA9535, PCA9539, PCAL9554, PCA9554 and PCA9538. On addition to this, this library is including mbed-SDK-style APIs. APIs that similar to DigitaiInOut, DigitalOut, DigitalIn, BusInOUt, BusOut and BusIn are available.

This is a copy of the PCA9555 library by Akifumi "Tedd" OKANO, which is compatible with PCAL6416A chip.
