如何利用藍(lán)牙智能設(shè)計(jì)LED智能照明系統(tǒng)

　　藍(lán)牙智能是最新的室內(nèi)LED燈的無線控制流行的選擇。隨著藍(lán)牙連接包括在每個(gè)智能手機(jī)和平板電腦，現(xiàn)成的界面為用戶提供了簡單的設(shè)置和控制燈。

　　使用智能手機(jī)使系統(tǒng)設(shè)計(jì)者有更多的選擇，實(shí)現(xiàn)新功能的燈，如改變平衡的顏色或光的質(zhì)量。

　　這種控制可以用的SimpleLink?cc2540t高溫?zé)o線收發(fā)器和德克薩斯儀器加TPS76933電壓調(diào)節(jié)器和tps62290 DC-DC變換器功率的燈實(shí)際LED控制器相結(jié)合的方法實(shí)現(xiàn)了。低功耗不是一個(gè)直接的問題，因?yàn)長ED燈往往是從電源供電，但低功耗設(shè)計(jì)意味著較低的工作溫度和更高的可靠性，使燈更長的壽命

　　A USB-based demonstration system includes a fully tested design with firmware， GUI， demo and getting started guide， and a full bill-of-materials.

　　The heart of the design is the CC2540T， which is packaged in a compact 6 x 6 mm 40-pin quad flat pack. This is a cost-effective， low-power， true wireless MCU for Bluetooth low energy applications based around an 8051 microcontroller core. The device enables a robust BLE master or slave node to be built with a very low total bill-of-materials by integrating in-system programmable flash memory， 8 KB of RAM， and other powerful supporting features and peripherals. The CC2540T is suitable for systems where very low power consumption is required as very low-power sleep modes are available. A short transition time between operating modes further enables low power consumption.
