Usage/Examples

To use the TCA9548A multiplexer, you will need to include the TCA9548A.h file in your project and create an instance of the TCA9548A class. You can then use the selectChannel() function to switch between the different I2C devices connected to the multiplexer.

#include "TCA9548A.h"

TCA9548A multiplexer;

void setup() {
  // Initialize the multiplexer
  multiplexer.begin();
}

void loop() {
  // Select channel 1
  multiplexer.selectChannel(1);

  // Perform I2C operations on devices connected to channel 1
}
