Has anyone an easy JTAG-Programmer-circuit? It should contain as few components as possible. I'm trying to get this circuit to work: http://mitglied.lycos.de/netman12345/programmer.png
But no success. I've made it based on this page: http://olimex.com/dev/
and left out the voltage regulator as it is always powered by the target- board. So if anyone has an easy circuit it would be fine!

Thank you for your answers. Now if finally found the answer: The programmer is correct, but the target-board not. I used the eagle library from a friend and he had mixed up the pin 27 and 28. After changing this everything worked fine.
