IOIO-Q : Android I/O board
introduction
The heart of IOIO-BOT is IOIO-Q Android input output board. IOIO-Q is compatible
with IOIO (pronounced “yo-yo”) original board (or IOIO V1) that designed by Ytai; Israel
computer engineer.The IOIO-Q is re-designed and produced by Innovative Experiment
Co.,Ltd (INEX- www.inex.co.th / www.inexglobal.com). The IOIO-Q is a board specially
designed to work with Android 1.5 and later device. The board provides robust connectivity
to an Android device via a USB or Bluetooth connection and is fully controllable from
within an Android application using a simple and intuitive Java API. No embedded
programming or external programmer will ever be needed!
The IOIO-Q board contains a single MCU that acts as a USB host and interprets
commands from an Android app. In addition, the IOIO-Q can interact with peripheral devices
in the same way as most MCUs. Digital Input/Output, PWM, Analog Input, I2C, SPI, and
UART control can all be used with the IOIO-Q. Code to control these interfaces is written
in the same way as you write an Android app with the help of a simple to use app-level
library. In other words, you can combine the awesome computing power, Internet/Bluetooth
connectivity, touch screen, and a variety of sensors from your Android device with the
ability to easily add peripheral devices to interact with the outside world. Also, using the
IOIO-Q does not require any hardware or software modifications to your Android device,
thus preserving the warranty as well as making the functionality available to non-hackers.
The IOIO-Q acts as a USB host and connects to most Android devices that have USB
slave (device) capability.
