Wigger小板电路原理图，实现简单的PC并口到JTAG接口的电平转换。可用来在PC机上通过JTAG 接口烧写目标板上的 Flash, 常用软件如 Flashpgm 等, 如加上 JTAG.exe 等 SERVER 软件,也可用 SDT 等软件进行源代码级的调试 -Wigger small plate circuit diagram, simple PC parallel port to JTAG interface-level change. Available on the PC through burning JTAG interface target board the Flash, If Flashpgm commonly used software, such as adding JTAG.exe SERVER software, SDT can also be used, such as software source code-level debugging
