支持多种芯片 USB高压编程器电路图源代码

主控芯片Mega16，单ZIF座不用跳线就可以支持多种芯片，用的是zhifeng的POWERPRG早期版本采用的协议。
USB高压编程器电路截图：

USB高压编程器版本V0.1说明几点：

上传的程序目前支持Mega8、Mega16\32、Mega8535；M48\88\168时序应该和Mega8是一样的，程序中考虑了扩展熔丝位，但是没有进行测试。
硬件上还可支持如下芯片，Tiny2313、Tiny13（及引脚定义相同的8DIP封装的芯片）、Tiny26、AT24C系列。
上位机软件是附件中的那个POWERPRG，不是zhifeng网上的那个，这个版本没法禁止SPIEN位。

USB高压编程器版本V0.1更新：

可以支持芯片如下：Mega8\48\88\168、Mega16\32\8535、Mega8515（待测）、Tiny2313、Tiny26(待测)、S5x（ISP方式，无法实现自动功能）；
增加转接模式，方便贴片封装的芯片，20针定义参见http://www.der-hammer.info/hvprog/index_en.htm，已用Mega64进行测试；
待测的原因是手头没有相应芯片；
需要将附件中的dat文件覆盖13楼中提供的原文件，硬件上有细微改动—将ZIF19和ZIF33连到PD7上，将ZIF2连到PC6上；
所有芯片和转接模式均是顶头对齐。
