It's been a long story that we launch Android Open Accessory Kits.
Project lauch. Project name : Android open accessory Kit-Robot Target launching : Early July
Robot design and tooling has started Made first evaluation sample Google suddenly announced ADK at Google IO. What???
Add the ADK version and delay the launching schedule
Final board ready, tooling finished, firmware debugging Launching
First customer shipping
Android accessory kit has turned out to be two different models. One is Bluetooth communication. The other is USB communication. The hardware is exactly same except the Bluetooth module. But the firmware is different and not exchangeable. Users need to choose which one is suitable for them. If you still want to change or write your own firmware, you must have a download tool such as a Microchip's PicKit-3/2.
Android API is open. So users can have their own app to controll the robot. One example is controlling the robot with google voice recognition API. If your phone has the Bluetooth feature, you are ready to enjoy this great accessory development regardless of Android version.
ODROID-ADK Controlling hardware with the Android smartphone application is another challenge for developers. We've test our ODROID-A, ODROID-7, Samsung Galaxy-S and Galaxy-S2 Gingerbread 2.3.4 update. But only the Galaxy-S2 doesn't work with ADK open accessory library. We don't know why !!
Open Accessory is a new capability for integrating connected peripherals with applications running on the platform. The capability is based on a USB (Universal Serial Bus) stack built into the platform and an API exposed to applications. Peripherals that attach to Android-powered devices as accessories connect as USB hosts. This was introduced with Android 3.1 Honeycomb and it is back ported in to Android 2.3.4 Gingerbread.
Hardkernel recently ported the latest Gingerbread 2.3.4 to ODROID-7 and we've tested the ADK feature with PIC24F based simple board. Enjoy this video and keep in touch~ We will make a new release for ODROID-7 and ODROID-A soon with this great Open Accessory Library.
