该编程器使用ISP并口下载线，所以电路相当简单。在这份资料中还 给出了一个ATmega8最小系统板的电路图和PCB，只要把ISP下载线接到该 系统板上即可下载程序到单片机里。-The programmer uses ISP parallel port download cable, so the circuit is quite simple. In this item are also given an ATmega8 minimum system board schem

通过IIC（I2C）和ISP总线来控制LCD1602,是Arduino的好帮手，有电路图和Arduino测试程序-Through the IIC (I2C) and ISP bus to control LCD1602, Arduino is a good helper, schematic and Arduino test procedures
