The HuskyLens module has a 4-pin interface for communication and power. The pinout is as follows:

For I2C communication, the module uses the following pins:

To use HuskyLens with an Arduino UNO, follow these steps:

1. Connect the VCC pin of HuskyLens to the 5V pin on the Arduino.
2. Connect the GND pin of HuskyLens to the GND pin on the Arduino.
3. For UART communication:
   • Connect the TX pin of HuskyLens to the RX pin (pin 0) on the Arduino.
   • Connect the RX pin of HuskyLens to the TX pin (pin 1) on the Arduino.
4. For I2C communication:
   • Connect the SCL pin of HuskyLens to the A5 pin on the Arduino.
   • Connect the SDA pin of HuskyLens to the A4 pin on the Arduino.

The following code demonstrates how to initialize HuskyLens and retrieve data using I2C communication:

#include <Wire.h>

// HuskyLens I2C address
#define HUSKYLENS_I2C_ADDRESS 0x32

void setup() {
  Wire.begin(); // Initialize I2C communication
  Serial.begin(9600); // Initialize serial communication for debugging

  // Send initialization command to HuskyLens
  Wire.beginTransmission(HUSKYLENS_I2C_ADDRESS);
  Wire.write(0x55); // Example command to initialize HuskyLens
  Wire.endTransmission();

  Serial.println("HuskyLens initialized.");
}

void loop() {
  // Request data from HuskyLens
  Wire.requestFrom(HUSKYLENS_I2C_ADDRESS, 8); // Request 8 bytes of data

  if (Wire.available()) {
    Serial.print("Data received: ");
    while (Wire.available()) {
      byte data = Wire.read(); // Read each byte
      Serial.print(data, HEX); // Print data in hexadecimal format
      Serial.print(" ");
    }
    Serial.println();
  }

  delay(500); // Wait for 500ms before the next request
}

• Ensure the HuskyLens module is powered within the specified voltage range (3.3V to 5V).
• Use level shifters if connecting to a 3.3V microcontroller to avoid damaging the module.
• For optimal performance, ensure the camera lens is clean and unobstructed.
• Use the HuskyLens interface to train the module for specific tasks (e.g., object recognition) before integrating it into your project.

1. HuskyLens is not responding to commands.

   • Ensure the module is powered correctly and the connections are secure.
   • Verify that the communication protocol (UART or I2C) is configured correctly in your code.

2. Data received from HuskyLens is incorrect or garbled.

   • Check the baud rate for UART communication (default is 9600).
   • Ensure the I2C address matches the one configured in your code (default is 0x32).

3. HuskyLens is not recognizing objects or faces.

   • Ensure the module has been trained for the specific task using its built-in interface.
   • Verify that the lighting conditions are adequate for the camera to capture clear images.

• Use the HuskyLens display to verify that the module is functioning correctly and detecting objects.
• Test the module with the official HuskyLens software or app to rule out hardware issues.
• If using UART communication, avoid connecting the module to the Arduino's hardware serial pins (0 and 1) while uploading code. Use a software serial library instead.

By following this documentation, you can effectively integrate HuskyLens into your projects and leverage its powerful AI capabilities for a wide range of applications.
