Adding usb host abilities to qpython on android to talk to arduino

[xp_prg]

Hi All,

I am making cell phone robots that talk to arduino.  I know how to do this in java:

https://github.com/wheath/myrobot/blob/master/phase2_5/android_sdk_proj/src/com/myrobot/myrobot/MyRobotActivity.java

Can I write a java fascade that interfaces with python for android to accomplish the goal of doing the same thing in python proper?  If so, where in the source code would I do this?  I am teaching boy scouts how to make cell phone robots if that makes you want to help me more :>

-Tim

P.S.

Here is the code in java:

line: 416

public void sendArduinoCmd(String cmd) {
	// Get UsbManager from Android.
	UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
	// Find the first available driver.
	UsbSerialDriver driver = UsbSerialProber.acquire(manager);
	try {
	if (driver != null) {
	driver.open();
	try {
	driver.setBaudRate(9600);
	byte buffer[] = new byte[2];
	byte[] cmd_array = cmd.getBytes();
	//buffer[0] = 'r';
	buffer[0] = cmd_array[0];
	Log.d("_dbg", "sending arduino command: " + buffer[0]);
	buffer[1] = '\n';
	int numBytesWrite = driver.write(buffer, 1000);
	Toast.makeText(getApplicationContext(),
	"Read " + numBytesWrite + " bytes.", Toast.LENGTH_LONG).show();
	} catch (IOException e) {
	// Deal with error.
	Toast.makeText(getApplicationContext(),
	"IOException occurred", Toast.LENGTH_LONG).show();
	} finally {
	driver.close();
	}
	} else {
	Log.d("_dbg", "arduino driver null");
	}
	} catch (IOException e) {
	// Deal with error.
	Toast.makeText(getApplicationContext(),
	"IOException occurred 2", Toast.LENGTH_LONG).show();
	}
	}

‎Hi Tim

Here is my usb facade for PL2032 chip.

This is just for USB serial facade sample, but

‎you can make same facade for arduino.
