bidirectional bus

They are particularly attractive for implementing buffer registers, I/ O ports, bidirectional bus drivers, and working registers.

他们为实现缓冲区寄存器，I/O端口，双向的总线驱动程序，并且工作的寄存器是特别地吸引人的。

How does GPRS/ 3G wireless module to achieve bidirectional communication between the bus terminal and the remote service center.

GPRS/3G无线网络模块如何实现将车载终端与远程服务中心的双向通信，远程服务中心实现对公交车的监控与调度。

This kind of interface provides 8-bit bidirectional communication, has data/ address bus, control bus and status bus, and responds to the requirement of interruption. It almost has the features of microcomputer bus and makes the design feasible theoretically.

并行接口在EPP模式下能实现8位数据的双向传输，具有数据/地址线、控制线和状态线，能响应中断请求，已初步具有总线的接口特性，为开发平台的实现提供了基础。

Combined with actual example, transparent bidirectional communication between CAN bus and the USB part of computer is realized by single chip processor and CAN controller. Moreover, the methods for software design and hardware realization are devised in this paper.

并结合开发实例，用单片机和CAN控制器实现了计算机USB口与CAN之间的两者之间的透明双向通信，给出了硬件电路的实现和软件设计的方法。

A component consisting of four separate receiver-transmitter combinations, designed for use with a bidirectional bus system, such as a data bus.

一种由四个独立的接收-发送器组合而成的部件，设计用于双向总线系统，如用在数据总线中。

So GPRS/ 3G wireless module can be attached on bus terminal to realize wireless data transmission and bidirectional communication between mobile bus and remote monitoring and dispatching service center.

所以可以在公交车车载终端挂接GPRS/3G无线模块，进行无线数据传输，实现移动公交车和远程监控调度服务中心的双向通讯，使远程监控调度服务中心能够实时地对移动公交车进行无线跟踪监控。
