The I2C bus was designed by Philips in the early 80 to allow easy communication between components which reside on the same circuit board. Philips Semiconductors migrated to NXP in 2006. Sometimes the bus is called IIC or I²C bus. This has features  like :  Only two bus lines are required No strict baud rate requirements like for instance with RS232, the master generates a bus clock Simple master/slave relationships exist between all components Each device connected to the bus is software-addressable by a unique address I2C is a true multi-master bus providing arbitration and collision detection Operation: The I2C bus uses two lines called Serial Clock Line (SCL) and Serial Data Lines (SDA). Both lines are pulled high via a resistor (Rpu) as shown in Figure below. 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. The Slave is any device addressed by t...

24LC512 is a 64K x 8 (512 Kbit) Serial EEPROMs(Electrically Erasable), from Microchip Technology Inc. (see the product page) . It has been developed for advanced, low-power applications such as personal communications and data acquisition. This device also has a page write capability of up to 128 bytes of data. This device is capable of both random and sequential reads up to the 512K boundary. Functional address lines allow up to eight devices on the same bus, for up to 4 Mbit address space. This is an example how to interface 24XXX EEPROMs with 8051. Best way is t0 use SDCC as C Compiler. the abobe schematic will be sufficient .  sample code  &    header  Datasheet - 24LC512 [pdf]

 there was  some  problem with co-linux DHCP enabled ,   while i loaded to vista HP , hence i did a static IP setting as follows: i have created eth1 interface to use the TAP adapter - i tried with ping ,read the colinux site ,did static IP , all dint work -i got clue that the TAP will allow access ,using slirp is lil tough -made a colinux.conf.txt from example.conf.txt added 1 more adapter with MAC 00:ff:00: ... -but fedora8 network settings are diffrrent ..sorted out added /etc/sysconfig/cfg-eth1 ,edited /etc/sysconfig/cfg-eth1 -in (vista)network connections ,EDITED the "TAP co-linux "adapter properties in IPv4 setting selected use the following IP :192.168.42.10 netmask 255.255.255.0 - i have disabled the vista firewall .....huh ! finally i was able to ping vista -------------> 192.168.42.10(TAP) vista ------------->192.168.42.10(TAP) ---->192.168.42.2(colinux-eth1,new interface) - added new liste...

Notebook Battery Life Most often used in notebook batteries of two types: lithium ion and nickel-metal Hydride (NiMH). Your notebook may give you a good freedom feeling on your travels for 3 or even more hours, but once the battery runs out, so does the freedom. If you travel not once a year, keep a spare notebook battery so that you'll never miss a important fair. A few simple rules can doubled battery life and make them safer: New battery before normal use must be trained, with a complete charge - discharge of 5-6 cycles / charging. To use the training mode bysroy batteries discharge: unplug the notebook from the wall outlet and turn it on. Use some active programme like scandisk for continuous operation. Lithium-ion batteries are particularly sensitive to heating. To avoid potential fire them should not be exposed to prolonged direct sunlight, for example, leaving the car in the cabin. Many producers indicate temperature batteries, it is necessary to draw attention to these figu...

Imagine you have some spare time , you are at a remote village .... wanted to watch your favorite movie /video and u just switch on a pocket device a big screen appears ,and your wall turns a cinema hall! Well, that technology is available and the Texas Instruments "Pico projector" is going for production..... It is a small sized projector , recharge , and use anywhere ! The little unit pumps out a WVGA (we think) 1000:1 image, which they found quite satisfactory, in addition to 0.5 watts of sound. The built-in battery should run the thing for a couple of hours.

What is the battery life of an ipod? well it is the number of hours the battery is able give a stabe specified voltage during its usage. You can improve the battery life of an iPod Shuffle by using iTunes effectively, limiting the extras you put in your music and by taking care of the portable music player. img: ipod suffle clipped Here i outline some simple tips how to do that : Step1 ## Use iTunes to create good playlists. Keep track of your current favorite songs and assemble them together on a small number of lists to limit the amount of fast forwarding and skipping you do. This helps extend the amount of play time that you get from your iPod Shuffle. Step2## Allow the iPod Shuffle to fully charge and you will improve the battery life. Lithium ion batteries are rechargeable, to a point. After about 400 charge cycles, the battery may have trouble storing as much charge. Partial charge cycles put the battery one step closer to needing replacement. Step3## Avoid putting eq...

We still haven't been able to shake the ViewSonic dragon from our memory, but we're attempting to move on with our lives by directing our attention (however briefly) to the N2201w. This so-called "3-in-1" LCD TV packs a 22-inch 1,680 x 1,050 resolution panel, a 5-millisecond response time, 1,000:1 contrast ratio and a built-in NTSC / ATSC / QAM TV tuner. You'll also find an integrated DVD player and an HDMI port, and just to prove it really is multifaceted, there's a PC input to boot. No telling if the picture quality is anything to write home about, but the $429 price tag sure is palatable.

We've been waiting ever patiently for this to get official, and at long last, that Project Projector we saw leaked in July has been revealed. Formally christened the M109S, this 0.8-pound beamer arrives with a native 858 x 600 resolution, a projection distance of up to 94.5-inches and a mercury-free LED light source that lasts up to four years. Moreover, it packs the ability to suck power from a Latitude or Vostro AC adapter if you're caught in a pinch, and yes, it's available today for $499 in the United States. As for the rest of the world, you wait.
