Atmel – Complete set of tools helps accelerate development of ZigBee Light Link projects

Atmel has introduced a set of tools and software which offer design engineers a quick, easy and safe means to develop wireless lighting control systems based on the ZigBee® LightLink profile.

The BitCloud Software Development Kit (SDK) provides a comprehensive set of tools, including full-featured reference applications, ZigBee PRO stack libraries and user  documentation. Using the SDK, users can quickly develop wireless products compliant with the ZigBee Home Automation profile as well as the LightLink profile.

The BitCloud SDK provides a reliable, scalable and secure wireless solution which supports large mesh networks consisting of hundreds of devices.

Offering ultra-low power consumption, it can provide for up to 15 years of battery life.

Applications developed with the BitCloud SDK may be targeted at Atmel® microcontrollers that feature a built-in ZigBee radio. These include the SAM R21 family of MCUs containing an ARM® Cortex®-M0+processor core, and the 8-bit ATmega256RFR2 and ATmega2564RFR2 MCUs. Atmel also supplies the ATmega256RFR2 ZigBit wireless module, which includes the MCU and an integrated chip antenna or UFL connector.

The SAM R21 devices are supported by the ATSAMR21ZLL-EK, a ZigBee Light Link evaluation kit featuring the ATSAMR21G18A MCU.

Supported by the Atmel Studio integrated development platform, the kit supports antenna diversity, and features an RGB LED, QTouch touch-sensing interface, OLED display, joystick, user LEDs, user switch, and external USB and UART interfaces.
