Greetings, I am new to JTAG and and I am working on a project that that has an Atmel AVR. I want to be able to use JTAG but have not bought any programming/debugging devices yet. I would like to get something that is compatible with other products that I see myself using in the future such as FPGAs or other microcontroller families. I am on a tight budget and I want to get something that will work with multiple devices.
Additionally, if all the chips that I use adhere to the IEEE standard, one JTAG device should do, right? I may be missing a major point and do not understand why is there a plethora of JTAG devices that are specific to a certain hardware or software.
Any help is greatly appreciated.
Thank you,
