Arduino library for operating TCA6416A

TCA6416A Arduino Library

This is an Arduino library for the TCA6416A, a 16-bit I/O expander for the I2C bus.

Installation in Arduino IDE

You should be able to install this library from the Arduino IDE's Library Manager. If you prefer to install it manually, follow these steps:

1. Download the library as a ZIP file.
2. In the Arduino IDE, go to Sketch > Include Library > Add .ZIP Library and select the downloaded file.

Usage

Include the library in your sketch:

#include <TCA6416A.h>

Create an instance of the TCA6416A class:

TCA6416A expander;

In your setup function, initialize the TCA6416A:

void setup() {
	while (!pins.begin(0, &Wire)) { // replace 0 with the address bit of your TCA6416A
    	Serial.println("TCA6416A not found");
		delay(1000);
	}
}

You can then use the various methods provided by the library to interact with the TCA6416A. For example, to set a pin as output and write a HIGH signal:

expander.pin_mode(0, OUTPUT);
expander.pin_write(0, HIGH);

To read the state of a pin:

int state = expander.pin_read(0);
