摘要
提出了用计算机的EPP协议实现计算机与其它设备间高速通讯的一种具体实现方法,详细介绍了EPP协议的信号定义、寄存器含义、工作时序 ,并通过 1个实例给出了单片机与计算机通过并行口进行双向数据传输的详细的技术解决方案 .
A kind of implementation of highspeed communication between parallel port and equipemnt in EPP mode is introduced.The definition of pins and registers of EPP is described,reading cycle and writing cycle of EPP is analyzed,and a typical solution for bidirect data transmission between a parallel port and a MCU is put forward in detail.
