2.4 GHz MRF24J40 ZENA USB Wireless Adapter
The ZENA™ Wireless Adapter ( AC182015-1 ) is a multi-function USB wireless adapter that connects USB-equipped desktop or notebook computers with Microchip wireless products for development or application uses. As a development tool, the ZENA Wireless Adapter can be used as a protocol analyzer or as a diagnostic tool. It can also be used to connect the computer as a wireless node to the network for application uses.
The ZENA Wireless Adapter can perform various functions and each function can be programmed in to the adapter using the built in USB boot loader. The ZENA Wireless Adapter is a flexible, multipurpose device. Firmware applications can be updated from a computer application program such as the Wireless Development Studio.
The ZENA Wireless Adapter is pre-programmed with a MiWi™ Wireless Protocol Sniffer application. This allows the user to display MiWi Wireless Protocol packets in a graphical format in the Wireless Development Studio. The ZENA Wireless Adapter has been designed to communicate with the Microchip MPLABComm driver which is based on the libusb-win32 (for Windows) and libusb (for Mac and Linux operating systems) libraries. The USB Drivers come with the Wireless Development Studio.
MiWi™ Development Environment is Microchip’s proprietary wireless solution which helps customers develop wireless applications and reduce the time to market. The MiWi Development Environment (MiWi DE) package includes support for Microchip’s proprietary protocols - MiWi Mesh and MiWi P2P. These protocols support short-range wireless networking applications.The MiWi Development Environment is optimized for low-power, low data rate, cost sensitive application. It also offers a smaller foot-print relative to the open standard based ZigBee® compliant protocol stack.
The MRF24J40 is an IEEE 802.15.4 Standard compliant 2.4 GHz RF transceiver. It integrates the PHY and MAC functionality in a single chip solution. A frequency synthesizer is clocked by an external 20 MHz crystal and generates a 2.4 GHz RF frequency.
