Code Examples
### Example 1: Using the HDMI to Micro HDMI Converter with an Android Smartphone
In this example, we will demonstrate how to use the HDMI to Micro HDMI Converter to output video from an Android smartphone to a standard HDMI monitor.
Hardware Requirements
Android smartphone with micro HDMI port
 HDMI to Micro HDMI Converter
 Standard HDMI monitor
Software Requirements
Android 4.0 or higher
Code
In this example, we will use the Android MediaProjection API to capture the screen and output it to the HDMI monitor.
```java
import android.hardware.display.DisplayManager;
import android.media.MediaProjection;
import android.media ProjectionManager;
public class HdmiOutputExample {
    private MediaProjection mediaProjection;
    private DisplayManager displayManager;
public void init() {
        // Get the display manager and media projection manager
        displayManager = (DisplayManager) getSystemService(Context.DISPLAY_SERVICE);
        ProjectionManager projectionManager = (ProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
// Create a media projection object
        mediaProjection = projectionManager.createProjection(DISPLAY_SERVICE, "HDMI Output");
// Create a virtual display to output to the HDMI monitor
        VirtualDisplay virtualDisplay = mediaProjection.createVirtualDisplay("HDMI Display", 1920, 1080, 60,flags);
// Set the virtual display as the default output
        displayManager.setFixedSize(virtualDisplay, 1920, 1080);
    }
public void startOutput() {
        // Start the media projection
        mediaProjection.start();
    }
}
```
### Example 2: Using the HDMI to Micro HDMI Converter with a Raspberry Pi
In this example, we will demonstrate how to use the HDMI to Micro HDMI Converter to output video from a Raspberry Pi to a standard HDMI monitor.
Hardware Requirements
Raspberry Pi with micro HDMI port
 HDMI to Micro HDMI Converter
 Standard HDMI monitor
Software Requirements
Raspbian OS
Code
In this example, we will use the Raspberry Pi's built-in `vcgencmd` command to set the HDMI output mode.
```bash
sudo vcgencmd set_output_mode 2
```
This will set the HDMI output mode to 1920x1080p@60Hz. You can adjust the output mode to match your specific requirements.
Note: Make sure to add the `hdmi_force_hotplug=1` option to your Raspberry Pi's `config.txt` file to enable HDMI hotplug detection.
These examples demonstrate the versatility of the HDMI to Micro HDMI Converter in various applications. Whether you're developing an Android app or building a project with a Raspberry Pi, this converter provides a convenient and compact solution for connecting to standard HDMI devices.
