There are many Serial Data Devices that means those that use the RS232 (old mouse port). USB is now the standard interface in most computers and embedded devices. Many mini embedded sensors and devices come with High Speed Serial Interfaces.

This page lists solutions and methods to get These Devices talking with your computer. The focus will be HandHeld Computers made of the Android OS. This way you can get your hand on the Real World thru USB and Serial. USB to parallel also helps when you want to control a Relay or Solenoid Array. Wireless Interfaces also are a good Solution with Networking.

Connecting Peripherals to an Android Platform

This white paper will describe some of the options for connecting peripheral accessories to Android OS based tablets/phones. The main focus will be the use of the Android Open Accessory Initiative.

Android is a Linux based operating system that is becoming very popular in mobile devices such as phones and tablets. The processor in current generation Android platforms is typically ARM based with the OS being optimised to support the hardware on the platform.

Many Android platforms are now supplied with On The Go (OTG) USB ports, allowing for the USB port to be either a host or a device. Some of these OTG ports will be USB device only i.e. they can only connect to a USB host as a USB device.
