Senior Design II – Đội 3 Truyền thông Ánh sáng có thể nhìn thấy – video 3
dự án của chúng tôi, You-Li, sẽ sử dụng ánh sáng nhìn thấy như một phương tiện truyền thông để truyền dữ liệu.
Visible Truyền thông Ánh sáng là một giao thức không dây thời gian gần đây đang nổi lên có thể có một số lợi ích và cách sử dụng cụ thể qua Wi-Fi.
Trong video này, we use a Beaglebone Black board to read ascii text from a terminal and output the binary conversion of the text to an LED panel. nguồn

BeagleBone Black Wireless boosts development
In terms of development boards, it’s not only about the Arduino and Raspberry Pi. The TI-friendly BeagleBone is there in the mix, too, fighting for your notice
Which is a acceptable reason to emphasize some developments around the BeagleBone Black single-board computer: there’s the new version and two new Capes from the BeagleBone team.
As well as the BeagleBone Black Wireless (down the page), additionally, there are two fresh ‘cape’ add-on boards for the existing BeagleBone Black.
BeagleBone Black Wireless
First off the BeagleBone Black Wireless, which is practically a BeagleBone Black with in-built 802.11 b/g/n 2.4GHz Wi-Fi as well as Bluetooth. It’s going after in the path of the Raspberry Pi 3 by building in Wi-Fi support to make easier wireless comms.
Its engine is the Texas Instruments Sitara AM3358 1GHz ARM Cortex-A8
“Just like the BeagleBone Black, the wireless preserves HDMI output, serial debug port, Computer USB interface, USB 2.0 host, reset and power control buttons, and brings two extra status LEDs for WiFi as well as Bluetooth,” states BeagleBone.org.
“Likewise stored is the 4GB of on board eMMC memory with Debian Linux preinstalled, empowering the BeagleBone Wireless to boot in roughly 10 secs and have you developing using your internet browser in less than 5 minutes by using basically a single USB cable.”
You can understand the details of the board by expanding the graphic previously mentioned, and a data sheet is the following for download.
Realize that it marks the introduction of the Octavo OSD3358 SiP, integrating BeagleBone functionality into one BGA package.

Considering the fact that we’re writing about mastercard-dimensions peices of kit, room is to be made for new features. This implies this particular BeagleBone has misplaced its 10/100 Ethernet port, creating room for a TI WL1835 WiLink wi-fi interface.
The complete specs:
:: AM335x 1GHz ARM Cortex-A8
:: SGX530 graphics accelerator
:: NEON floating-point accelerator
:: 2x PRU 32bit 200Megahertz micro-controllers
:: WiLink 1835 802.11b/g/n 2.4GHz WiFi, Bluetooth, and Bluetooth Smart Module
:: USB client: power, debug and device
:: USB host
:: Micro High definition multimedia interface output
:: 2x 46 pin headers
:: 512Megabyte DDR3 800MHZ RAM
:: 4GB Built-in eMMC Flash with Debian Distribution pre-installed
:: micro sdcard Slot
Software Match ups
:: Cloud9 IDE on Node.js w/ BoneScript library
And also the the two new capes…
Wireless Cape addon
Be aware that the new Wireless Cape takes BeagleBone Black beyond the functions of BeagleBone Black Wireless, indicates Steve Bush in his news piece about the release. It’s powered by Texas Instruments WiLink 8 (WL1837) industrial dual-band (2.4GHz and 5GHz), 2×2 MIMO Wi-Fi, BT and Bluetooth Smart (often referred to as BT LE), which also carries Zigbee & NFC.
The cape is offered with Debian Distribution pre-installed and 4GB of on board eMMC Flash memory. “Developers can be developing employing their internet browser in fewer than 5 minutes with a single USB cable,” said Farnell.
Display cape addon
Be aware there’s also a Display cape addon made available. It includes connections for a 4.3inch colour touchscreen an LED backlight and capacitive overlay “for a phone-like interface”.
The cape is aimed at interactive projects, embedded systems and stand-alone installations.
Cost is about ￡55 for the BeagleBone Black Wireless, ￡35 for the display cape addon and ￡44 for the wireless cape addon .
