Low-cost Embedded Wireless Connectivity for Commercial and Smart Home Networks
MiWi™ Protocol
Developed to enable low-cost, commercial and smart home networks, MiWi is used in applications such HVAC systems and alarm sensors where reliable self-healing mesh networking is needed. MiWi supports operation the IEEE 802.15.4 radio PHY in the sub-GHz and 2.4 GHz ISM bands.
The MiWi stack offers a significantly smaller foot-print relative to the open standard based ZigBee® compliant protocol stack. This enables operation in microcontrollers with smaller memory/lower cost. A typical end node requires only 20 KB of code space.
Microchip’s MiWi Mesh Stack is now available for Atmel Studio 7 the Integrated Development Platform (IDP) for developing and debugging all AVR® and SAM microcontroller applications. The Atmel Studio 7 IDP gives you a seamless and easy-to-use environment to write, build and debug your applications written in C/C++ or assembly code.
Atmel Studio 7 is available at: http://www.microchip.com/avr-support/atmel-studio-7 and the MiWi Mesh code is part of the latest Advanced Software Framework (ASF) release for Studio, available at: http://www.microchip.com/avr-support/advanced-software-framework-(asf).
