Wireless Radio Module Chip45 iDwaRF-168
iDwaRF-168 - Programmable 2.4GHz Radio Module with AVR ATmega168.
Detailed Description
The programmable wireless radio module iDwaRF-168 combines a Cypress 2.4GHz DSSS radio transceiver with an Atmel AVR ATmega168 microcontroller.
In combination with the free iDwaRF-Net firmware a powerfull and expandable platform for custom specific wireless application is available.
Firmware
The freely available iDwaRF-Net firmware provides the complete functionality for a wireless, star-like N:1 sensor network. The wireless protocol is completely encapsulated, for data transmission and communication between host (e.g. PC) and iDwaRF hub a simple serial ASCII protocol is implemented. Additional user functions can be easily embedded into the sensor firmware and simple data structures are used for communication. Several example allications, e.g. covering the onboard components of the iDwaRF-NodeBoard or a wireless chat via terminal programms, can easily be adapted to own applications.
