Conecta facilmente sensores y actuadores externos a un dispositivo Android

?

El IOIO (pronunciado "yo-yo") es una placa especificamente dise?ada para trabajar con dispositivos Android (versi?n del OS superior a v1.5). Proporciona una conectividad robusta con un dispositivo android por conexi?n USB y es totalmente controlable desde una aplicaci?n Android usando una simple e intuitiva API de JAVA llamada?IOIO Manager

La lista de dispositivos que funcionan sin problema se va alargando cada d?a m?s. Por el momento, est?n confirmados: G1, Nexus One, Nexus S, Motorola Droid X.

?

El IOIO continene un peque?o microcontrolador que act?a como USB Host e interpreta las peticiones de la aplicaci?n Android. Por otro lado, el microcontrolador puede interactuar con otro dispositivos f?sicos conectados al mismo tales como sensores, actuadores etc utilizando las se?ales y protocolos convencionales tales como entradas y salidas digitales, PWM, entradas anal?gicas, I2C, SPI y UART, todas ellas pueden ser utilizadas. El c?digo para controlar estas interfaces se escribe de la misma forma que se escribe una aplicaci?n de Android usando una peque?a librer?a. En otras palabras, el IOIO permite aprovecharse de la gran potencia de c?lculo de los dispositivos m?viles con Android, Internet/Bluetooth, conectividad Wifi, touchscreen y conectarlo con perif?ricos externos de forma sencilla.

Adem?s, para utilizar IOIO no es necesaria ninguna modificaci?n al tel?fono por lo que conservas la garant?a, si te importa ese dato claro :)

Si eres nuevo en el desarrollo de aplicaciones con Android y IOIO, te dejamos un par de enlaces con tutoriales y documentaci?n (en ingl?s):

Para actualizaciones de firmware, puedes descargarte la?IOIO Manager app?(tiene un c?digo QR a la derecha). Tambi?n existe la?IOIO Manager wiki?si necesitas m?s informaci?n.

Actualizaci?n: ahora la IOIO dispone de un firmware beta que soporta el protocolo ADK de Google. El fuente est??aqu?.

IOIO-OTG
DEV-11343??

Description:?Are you a Java developer looking to add advanced hardware I/O capabilities to your Android or PC application? Well then the IOIO-OTG is for you! The IOIO-OTG (pronounced ?yo-yo-O-T-G?) is a development board specially designed to do just that. It features a PIC microcontroller which acts like a bridge that connects an app on your PC or Android device to low-level peripherals like GPIO, PWM, ADC, I2C, SPI, and UART. An app-level library helps you write control code for these low level peripherals in the same way you'd write any other Java app!

What separates the IOIO-OTG from previous IOIO boards is the ability to leverage the USB On-The-Go specification to connect as a host?or?an accessory. There are several ways to connect the IOIO to your Java app. If the app is running on your Android device, the IOIO-OTG will act as a USB host and supply charging current to your device (meaning the IOIO-OTG will need its own power source). If your app is running on a Windows, Linux or OSX machine, the IOIO-OTG will assume device mode and present itself as a virtual serial port. When in device mode, the IOIO-OTG can be powered by the host! Connecting a USB Bluetooth dongle will cause the IOIO-OTG to show up as a Bluetooth serial connection so you can go wireless!

A switch on the board can be used to force the IOIO-OTG into host mode, but most of the time the board can be left in 'auto' mode and it will detect its role in the connection. We're now shipping the IOIO-OTG board loaded with the V4.00 bootloader and the V3.30 application firmware. New application firmware is frequently released, and can be upgraded without needing a programmer using the IOIODude application.

The board includes a JST connector for attaching a LiPo battery and there are several pin headers broken out for voltage and ground access. A trimpot on the board allows you to adjust the charge current used when the IOIO-OTG is acting as a host. A USB-A to micro-A OTG cable is included which will let you connect your android device to the micro-USB port on the board using the cable that came with your android device.
