Test ADKTerminalTest example of Arduino 1.5.2, with Android ADK terminal emulator for Arduino

Arduino 1.5.2 provide a ADKTerminalTest example to demonstrates USB Host connectivity between an Android phone and an Arduino Due. It provide source code in Arduino Due side, and url to load Android APK from "http://labs.arduino.cc/uploads/ADK/ArduinoTerminal/ThibaultTerminal_ICS_0001.apk". But I can't find the source code of ThibaultTerminal_ICS_0001. Alternatively, I found "Android ADK terminal emulator for Arduino (ArduinoTerminal)" with source code provided.

In this post, I will describe how to make ADKTerminalTest example work with ArduinoTerminal. In next post, I will show how to import and setup ArduinoTerminalSrc in Android Developer Tools. After finished, you can connect and send text between Arduino Due and Nexus One running Android 2.3.6.

Arduino Due work with Nexus One

To load ADKTerminalTest example of Arduino 1.5.2, select File -> Examples -> USBHost -> ADKTerminalTest.

ADKTerminalTest example in Arduino 1.5.2

Modify on Arduino code:

• Modify adk() parameters to match with Android side. To acknowledge the originator of Android ADK terminal emulator for Arduino, I use the original counter part.
• Add the code Serial.begin(9600) in setup() method.
