The Raspberry PiRaspberry Pi is a single-board computer developed in the UK by the Raspberry Pi Foundation. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 or 512 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.

The foundation has released two versions; Model A & Model B.

Model B (Revision 2.0) - It's a latest launched Raspberry Pi Revision 2 with 512MB of RAM memory, two USB ports and a 10/100 Ethernet controller. Click Here to Learn What's New?

Model B (Revision 1.0) - has 256MB RAM memory, two USB ports and a 10/100 Ethernet controller.

Model A - has 256 Megabytes (MB) RAM memory, one USB port and no Ethernet controller. Though the Model A doesn't have an RJ45 Ethernet port, it can connect to a network by using a user supplied USB Ethernet or Wi-Fi adapter. As typical of modern computers, generic USB keyboards and mice are compatible with the Raspberry Pi.

The Raspberry Pi use Linux-kernel based operating systems. Debian GNU/Linux, Iceweasel, Calligra Suite and Python are planned to be bundled with the Raspberry Pi. The Raspberry Pi does not come with a real-time clock, so an OS must use a network time server, or ask the user for time information at boot time to get access to time and date info for file time and date stamping. However a real time clock (such as the DS1307) with battery backup can be easily added via the I²C interface.

The Raspberry Pi Foundation has released various SD Card image that can be loaded onto an SD Card to produce a preliminary operating system. The image is based upon Linux version of Debian OS (Raspbian) with the LXDE desktop and the Midori browser, plus various programming tools. The image can also run on QEMU allowing the Raspberry Pi to be emulated on various other platforms.

niche over 13 years ago

I've just joined and looking for a way to read analog inputs 0 to 5v at 14 to 16 bits, it looks as if a dedicated analog
input is not available so a bit dissappointed with that as it could have opened up a lot of possibilities for a small controller
with easier PID etc, so that means the analog needs to be supplied with a peripheral chip and associated support circuitry.

Any suggestions as to the fastest way to get a 14 to 16 bit data value from an external ADC into
a cpu register for subsequent processing, any suggestions on a contender ?

I imagine using I2C would be the slowest though maybe the smallest, how about latched
parallel input from a suitable ADC which outputs a 16 bit value ?

Thanks

Is there an accurate scale drawing of the Raspberry Pi board? It would be helpful in making a case to mount it in.
What is the best way to mount the board? Are there holes for mounting posts?

The videoes source from YouTube. Maybe some regions are limited to access YouTube, such as Chinese Mainland.

Are you in Chinese Mainland?
