 Full-featured custom component for the **TCA6408** 8-bit I²C I/O Expander.

 ## Features
+
 - 8 bidirectional GPIO pins
- Hardware polarity inversion (inputs)
- **Interrupt-driven** inputs (active-low)
- Polling fallback
- Cached GPIO expander (efficient)
- Works on ESP32 (incl. C5), ESP8266, etc.
+- Hardware polarity inversion support (inputs)
+- Interrupt-driven inputs (active-low INT pin)
+- Efficient cached GPIO expander
+- Polling fallback mode
+- Compatible with ESP32 (including C3/C5/C6), ESP8266, etc.

 ## Installation
