Considering The Jtag Wiggler
A popular trend of late is using a very simple cable called a JTAG cable to connect two devices together. One very simple solution is to use a unique cable called a JTAG Wiggler, as is it is proving to be a simple way to get the job done for many different types of applications. What is really nice about the Wiggler is that is will connect to a standard parallel port of a computer, and you will find that these ports are available on almost any PC. You are going to run in to some newer computers who do not have a parallel port, but what is really convenient is that you can purchase a parallel port card for less than ten dollars and install it on your computer and you will be Wiggler ready at this point. In this article we are going to take a brief look at this very unique and effective JTAG cable and learn why it is so useful to us. The really excellent aspect of a Wiggler cable is that it can be used for cable connections and it can also be used for BDM debugging. It is really convenient because it will connect to any parallel port on a personal computer, and if you do not have this type of port it can easily be added to your existing PC. This device is will not fluctuate while it is performing, it is very easy to use, as well as be extremely simple. The most important aspect of the Wiggler is that is has an low cost of setup, and an even lower cost when using it for processor programming and reprogramming. Once you connect to the parallel port of the host computer the business side of the cable will connect to an on chip debug port of the intended target device, computer, or machine. There are several different types of configureations for the target that is useable such as COP, CBD, and JTAG being the most popular and universal. You will find that as you shop around the Wiggler will consistently be the most cost effective type of JTAG cable you can find. Often times these unique JTAG devices will support a clock rate between fifty kilohertz to approximately four hundred kilohertz. It is recommended for the best performance that your Wiggler connection will hook up with an enhanced parallel port, also known as an EPP. It will also work with other types of parallel ports but your overall performance will not be as efficient. What is really optimal with the Wiggler is that it will work quite well with a Windows configured host. One such host that works very well is called the OCD Remote which can easily be used with any Wiggler compatible cable. A very popular windows application tool functions as a utility is called JTAG tools, and it will run well on either Windows or Linux applications. If you are just starting out, and possibly have an Xbox 360 application in mind, you will want to first consider a Wiggler for your JTAG type projects. You will find that this type of JTAG is easiest to use, and have the most universal compatibility of any of your other options. You can not go wrong with a Wiggler cable if you are just getting started with JTAG. If you would like add connectivity and programming capabilities between your devices then consider adding a JTAG cable.
