[android-developers] Re: control micro-controller or any Hardware

There are basically three ways:

1) If you can constrict it to Android devices with USB host capability
and Android > 3.1 (basically good android tablets), you can use the
USB APIs with the android device as Master (see
http://developer.android.com/sdk/android-3.1.html, section "USB
APIs").

2) If you don't have USB host capability in the android devices, you
can use the USB APIs with a "USB accessory" (see the same link as
above). However, this still requires at least Android 3.1 and "USB
accessory" basically means your USB hardware has to be designed &
programmed for this.

3) If you want to implement your solution for "all" (well, actually
most) android devices, even prior to Android 3.1, you need special USB
Host hardware. A simple way to go is the IOIO board. Basically, it's a
microprocessor board based on a PIC microprocessor with USB host
support and a (freely available) firmware & and an Android library
that can communicate with each other. This board can be connected to
the normal USB connector you use to connect your android device with a
PC.
