AVR Dragon – Its Features and Usage

When it comes to setting standards for developing low cost tools for 32-bit and 8-bit AVR devices with OCD or On Chip Debug capability, the AVR Dragon has played an instrumental role. It is capable of performing a debugger, which is symbolic in nature on all the OCD devices with JTAG, selected PDI devices, a Wire mode, parallel programming, high voltage serial programming, OCD and helps in supporting debugging by using JTAG, PDI and SPI interfaces. The designers are allowed to add sockets, build personalized circuitry which would fit best in the footprint of the device.  The debugger, with the help of the memory of the target device supports NanoTrace; it depends on the OCD Module. 

Main Features

Here are some of the key features of AVR Dragon:

• 1 maskable data breakpoint or 3 hardware program breakpoints are supported by it
• However, it depends on the OCD module
• Software breakpoints up to 32 is supported
• For fast statement-level stepping it comes with an integrated 128kB SRAM
• A target operation from 1.8v to 5.5v is being supported by the converters
• It is capable of uploading 256Kb is half a minute by using a JTAG interface

Full-speed USB 2.0 compliant host interface 

• The firmware can be upgraded to support the AVR devices in the future
• Nano Trace is supported
• It is being powered by USB and can also supply power to any external device

All about ZigBee and its Wireless Products

The ZigBee Wireless products offer low power solutions which enable the devices to continue functioning for a longer period of time using relatively inexpensive batteries. The ZigBee standards have played a very vital role when it comes to automating and connecting an array of different types of devices which are used on a daily basis. Control and security devices, HVAC, home lighting, and other which are used in residential and commercial properties.

• What is ZigBee?

ZigBee is nothing but a wireless protocol technology, which is based on global standards. It is an open standard.  It is designed with the view to address the requirements in the field sensor network application, remote control and monitoring. With the help of ZigBee wireless standards, it is possible to deploy wireless mesh on a broader scale at a very low and reasonable rate.

ZigBee Alliance – What is it?

The ZigBee Alliance is a huge concept. It is a scenario where more than 400 companies from all over the world are developing wireless solutions which can be used for home security, home automation, and smart metering in industrial applications, commercial buildings and residential complexes. The companies which are a part of the ZigBee Alliance are working together in order produce cost-effective, reliable, wirelessly networked, low-power, control and monitoring products which are being built on a global standard. The ZigBee Wireless devices have proved to be instrumental in providing reliable and authentic wireless solutions.

• ZigBee Alliance – Its Focus

The followings are the areas of focus for the ZigBee Alliance:

• Defining the security, network, software layers and application.

• Providing conformance and interoperability testing specifications.

• Creating market awareness by promoting the brand of ZigBee on a global platform.

• To manage and control the technological evolution.

Benefits of the ZigBee Protocol

There are a couple of benefits which the ZigBee Protocol has to offer. The main benefits include vendor accessibility and the interdependence of markets which are broader in terms of scope. The networking layers and the physical radio have been designed as per industry standards which help in more innovative approach towards new ZigBee Wireless device development.

In the ZigBee protocol specification, there is a set of expanded features which is known as ZigBee PRO. It is known as ZigBee PRO Feature Set. It helps to maximize the capabilities of ZigBee specifications. It also comes handy when it comes to facilitating support over large networks and ease of use.

The ZigBee Wireless devices have made a mark in the field of networking and gradually they are turning out to be indispensable in this domain. To get quality devices you can easily approach the professional manufacturers and equipment providers.
