81. I2C Bus And Access Bus Pinout The I2C bus uses a bidirectional serial Clock Line SCL and serial Data Lines SDA . Bus uses the I2C bus as the electrical hardware interface. http://www.interfacebus.com/Design_Connector_I2C.html

I C Bus / Access Bus I C Description Access Bus Description Interface ICs ... Home I C Bus Description I C bus [Inter-IC Bus] or [IIC Bus] was originally designed to be a battery control interface. The I C bus uses a bi-directional Serial Clock Line [SCL] and Serial Data Lines [SDA]. Both lines are pulled high via a resistor [Rp]. Resistor Rs is optional, and used for ESD protection for 'Hot-Swap' devices. No other lines are specified. Three speed modes are specified: Standard; 100kbps [Bits per Second], Fast mode; 400kbps, High speed mode 3.4Mbps. I2C, due to its two-wire nature (one clock, one data) can only communicate half-duplex. The maximum bus capacitance is 400pF, which sets the maximum number of devices on the bus and the maximum line length. The interface uses 8 bit long bytes, MSB [Most Significant Bit] first, with each device having a unique address. Any device may be a Transmitter or Receiver, and a Master or Slave. Data and clock are sent from the Master ~ valid while the clock line is high. The link may have multiple Masters and Slaves on the bus, but only one Master may be active at any one time. Slaves may receive or transmit data to the master. I C defines the electrical layer and protocol, and was developed by Philips Semiconductors. V

Mouse Support in X11R6.8.2 Supported Hardware Previous: Introduction Next: OS Support for Mice 2. Supported Hardware The X.org Foundation X server supports three classes of mice: serial, bus and PS/2 mice. Serial mouse The serial mouse has been the most popular pointing device for PCs. There have been numerous serial mouse models from a number of manufactures. Despite the wide range of variations, there have been relatively few protocols (data format) with which the serial mouse talks to the host computer. The modern serial mouse conforms to the PnP COM device specification so that the host computer can automatically detect the mouse and load an appropriate driver. The X server supports this specification and can detect popular PnP serial mouse models on most platforms. Bus mouse The bus mouse connects to a dedicated interface card in an expansion slot. Some video cards, notably those from ATI, and integrated I/O cards may also have a bus mouse connector. Some bus mice are known as `InPort mouse'. Note that some mouse manufactures have sold a package including a serial mouse and a serial interface card. Don't confuse this type of products with the genuine bus mouse. PS/2 mouse They are sometimes called `Mouse-port mouse'. The PS/2 mouse is becoming increasingly common and popular.

/* Accessible by controls */ USB 2.0 Hi-speed Flash drive roundup 1 - Introduction 2 - How we tested 3 - Meet the contenders 4 - More contenders 5 - Final contenders 6 - Read performance benchmarks 7 - Write performance benchmarks 8 - A Flash drive RAID-0 array? 9 - Conclusion 10 - Comparison matrix By Matt Woodward Thursday, June 03, 2004 Introduction Whether you refer to it as a pen drive, jump drive, thumb drive, key drive, or memory stick, you have to admit, the USB Flash drive is pretty darn cool. Just stick it into the USB port on your computer and within a few seconds a new drive appears on your desktop. So simple and so easy. What makes them so good is that they have a spate of desirable features such as no need for batteries, solid state storage, good transfer speeds, durability, portability, and expected data retention of ten years. All of these features allow these little babies to practically replace the floppy, the Zip disk, and the CD-R/RW all in one fell swoop. Unfortunately, when comparing USB Flash drives side-by-side in a computer or electronics store, it can be awfully difficult to decide which is best for you just by looking at the drive and the packaging. It would be easy to make an assumption that all drives are pretty much the same and that shopping for the best price is the smartest way of deciding. We are here to inform you that USB Flash drives are not a commodity and can be very unique offerings. As you will soon find out, some are clearly better than others while others come bundled with nifty features that can really make your day. In short, not all flash drives are created equal.

OpenBSD/i386 OpenBSD/i386 runs on the standard PC's and clones, with a wide variety of processors, I/O bus architectures and peripherals supported. Table of contents History of the port Current status Supported hardware Installation with other operating systems ... Getting and installing OpenBSD/i386 History: The OpenBSD/i386 port has been present since the inception of the project. Over the years, more and more hardware support has been written specifically for OpenBSD (such as the cryptographic accelerator drivers), or adapted from FreeBSD and NetBSD. Current status: It can be expected to install and run with minimal difficulty on most current hardware. Machines using custom BIOS (such as older proprietary PC's, laptops, and some specialized server machines) may cause problems. Through its binary compatibility layer, OpenBSD/i386 can run Linux, FreeBSD, BSD/OS, SVR4 (including Solaris) and IBCS2 binaries, to some extent. Most applications will work flawlessly. X Window System support is available for most graphics cards, using either the recent X.Org (6.8.2 as of OpenBSD 3.7) server whenever possible, or XFree86 3.3.6 servers otherwise. Supported hardware: Most laptops are supported. We have
