IOIO-OTG for Android with USB OTG Cable
The IOIO-OTG for Android with USB OTG Cable is a development board that enables users to connect Android devices to external hardware components and peripherals. It is based on the IOIO (pronounced "yo-yo") open-source hardware platform, which provides a convenient and flexible way to interface with various devices and sensors.
Features:
Compatible with Android devices that support USB OTG (On-The-Go) technology
Allows bidirectional communication between Android devices and external hardware components
Supports up to 48 digital I/O pins, 16 analog input pins, and 6 pwm output pins
Onboard 3.3V voltage regulator for powering external devices
Includes a USB OTG cable for connecting to Android devices
Code Examples:
### Example 1: Reading Analog Input Values
This example demonstrates how to use the IOIO-OTG board to read analog input values from a potentiometer connected to analog input pin 0.
Android Code (Java):
```java
import ioio.lib.api.IOIO;
import ioio.lib.api.IOIOFactory;
import ioio.lib.api.AnalogInput;
import ioio.lib.api.exception.ConnectionLostException;
public class AnalogReaderActivity extends AppCompatActivity {
private IOIO ioio_;
private AnalogInput analogInput_;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_analog_reader);
// Initialize IOIO board
try {
ioio_ = IOIOFactory.create();
} catch (ConnectionLostException e) {
Log.e("IOIO", "IOIO connection lost");
}
// Get analog input pin 0
analogInput_ = ioio_.openAnalogInput(0);
// Read analog input value
float inputValue = analogInput_.getVoltage();
Log.d("AnalogReader", "Input value: " + inputValue);
}
}
```
IOIO-OTG Board Connection:
Connect the potentiometer to analog input pin 0 on the IOIO-OTG board
Connect the USB OTG cable to the Android device and the IOIO-OTG board
### Example 2: Controlling an LED using Digital Output
This example demonstrates how to use the IOIO-OTG board to control an LED connected to digital output pin 13.
Android Code (Java):
```java
import ioio.lib.api.IOIO;
import ioio.lib.api.IOIOFactory;
import ioio.lib.api.DigitalOutput;
import ioio.lib.api.exception.ConnectionLostException;
public class LedControllerActivity extends AppCompatActivity {
private IOIO ioio_;
private DigitalOutput ledOutput_;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_led_controller);
// Initialize IOIO board
try {
ioio_ = IOIOFactory.create();
} catch (ConnectionLostException e) {
Log.e("IOIO", "IOIO connection lost");
}
// Get digital output pin 13
ledOutput_ = ioio_.openDigitalOutput(13);
// Set LED to HIGH (on)
ledOutput_.write(true);
Log.d("LedController", "LED is on");
// Set LED to LOW (off)
ledOutput_.write(false);
Log.d("LedController", "LED is off");
}
}
```
IOIO-OTG Board Connection:
Connect the LED to digital output pin 13 on the IOIO-OTG board
Connect the USB OTG cable to the Android device and the IOIO-OTG board
These examples demonstrate the basic usage of the IOIO-OTG board with Android devices. You can explore more advanced applications, such as reading sensor data, controlling motors, and interacting with other peripherals, by using the IOIO-OTG board's various features and APIs.
