IEEE1284并行接口实现

The Implementation of IEEE 1284 Parallel Port

首先介绍了W912 84PIC ,然后给出了基于W912 84PIC的IEEE 12 84并行接口的硬件实现电路图 ,最后在这种电路图的基础上给出了软件实现。

First introduces W91284PIC. Then illustrates the circuit diagram of IEEE 1284 parallel port implementation. At last,uses program to implement the parallel port on base of the hardware design.
