AVR JTAGICE 仿真器是AVR单片机开发中的有力帮手，本文详细介绍了如何自己动手制作。-AVR JTAGICE emulator AVR are development of a powerful single-chip to help, this article details how to create it yourself.

The AT89C2051/ATtiny2313 evaluation board is suited well for building and testing microcontroller circuits. You can either use an AT89C2051 or an ATtiny2313, both microcontrollers are almost pincompatible, just the reset pin has different polarity. T
