BeagleBone Black Using Python
BeagleBone Black - Open Source Development Platform Introduction : The BeagleBone black is an embedded Linux development board that’s a credit card sized linux computer. It’s a smaller, more barebone version of BeagleBoard. Both are open source hardware and use Texas Instruments’ processors with an 1 GHz Sitara AM335x ARM® Cortex™-A8 processor, which are designed for low-power mobile devices. This BeagleBone Black Boot Linux in under 10-seconds and get started on processor development in less than 5 minutes with just a single USB cable. BleagleBone Black comes with Angstrom Linux distrubution in onboard FLASH to start evaluation and developement. Angstrom Linux is Opkg Package based operating system, Opkg is a lightweight package management system based up on ipkg. It is written in C and resembles APT/dpkg in operaton. It is intended for use on embedded Linux devices and is used in this capacity in the OpenEmbedded and OpenWrt project and which are belongs to Google Code repository. The software platform is based on the Angstrom GNU/Linux distribution and is equipped with a distributed file system to ease sharing data and code among the nodes of the cluster, and with tools for managing tasks and monitoring the status of each node. Features: The BeagleBone Black as nothing more than a small, standalone Linux computer, but the hardware is designed for use as an embedded system – a computer installed inside of a large electronics project.The main evidance of theis is in the two rows of GPIO ( general puropose Input/ Output) pins moujnted along either side of the board. These pins allow the Beaglebone Black to communicate with a wide range of sensors, servos, outputs and other hardware, letting it act as the brain of a large, complex project. The BeagleBone Black features: •TI Sitara AM3359 1-GHz superscalar ARM Cortex™-A8 •2x 200MHz ARM7 programmable real-time coprocessors •512-MB DDR3L RAM •2GB eMMC •PowerVR SGX 530 GPU, LCD expansion header, micro HDMI •Stereo audio-out via HDMI •1x USB 2.0 host port •1x USB 2.0 device port •On-chip 10/100 Ethernet, not off of USB •MicroSD slot •Add-on "capes" for expansion, compatible with original Bone capes •1 power LED and 4 user controllable LEDs via GPIO •Industry standard 3.3V I/Os on the expansion headers with easy-to-use 0.1" spacing •Multiple I/O bus: GPMC (nand), MMC, SPI, I2C, CAN, McASP, MMC, 4 Timers, XDMA interrupt •5 serial ports (1 via debug header, 4 more on side headers) •65 GPIO pins •8 PWM outputs •7 12-bit A/D converters (1.8V max) •Board size: 3.4” × 2.1” Pinout: Beagle Bone Black’s Capabilites can be extended using plug-in boards called “capes” that can be plugged into BeagleBone Black’s two 46-pin dual-row expansion headers. Capes are avilable for, VGA, LCD, motor control, prototyping, battery power and other functionality. Power consumption is also lower, with the board only req
