It is used primarily for broadcasting messages over a network. In medical imaging, UDP is used to log information from various devices to a system logging repository. A datagram is a piece of a message transmitted over a packet-switching network, and is a packet of information that contains the destination address in addition to data. • Channel 1: GPCLK/UART—This channel can be used as a general purpose clock (GPCLK) or universal asynchronous receiver-transmitter (UART).

Channel 1 GPCLK UART This channel can be used as a general purpose clock GPCLK or universal asynchronous receiver-transmitter UART . See Channel 3 for a more detailed description. Channel 2 Infrared Data Association IrDA is a group of device manufacturers that developed a standard for transmitting data via IR light waves. Increasingly computers and other devices such as printers come with IrDA ports. This enables you to transfer data 8 Chapter 1 Anatomy of a Personal Digital Assistant PDA from one device to another without any cables. For example if both your laptop computer and printer have IrDA ports you can simply put your computer in front of the printer and output a document without needing to connect the two with a cable. IrDA ports support roughly the same transmission rates as traditional parallel ports. The only restrictions on their use are that the two devices must be within a few feet of each other and there must be a clear line of sight between them. The IrDA port on the PDA will be the main communication link to PDA-Bot in essence it will be the spinal cord. PDA Robot responds to IrDA discovery requests and identifies itself as generic IrDA. I decided to use an IrDA data link to the Robot because it is a very reliable communication link error correction is built into it that requires absolutely no cables See .
