Abstract

The disclosed read-write serial interface bus communication controller with SPI interface comprises: a communication assembly, which includes the bus included both of a serial asynchronous receiver-transmitter and a connected buffer process unit 2 and the logic control part included a control unit, an error counting and processing circuit, and a carrier detection multi-address access conflict monitor circuit; a data buffer process unit 1; an interface controller; a SPI interface; and an EFPROM. This invention simplifies control logic for CPU to introduce convenience for user and provider.

Description

technical field [0001] The invention relates to a control device for controlling a network, in particular to a control device with interface and communication functions for controlling a network. Background technique [0002] In the past, the multi-address communication between single-chip microcomputer and single-chip microcomputer, or single-chip microcomputer and PC personal computer generally used parallel interface to carry out serial bus communication. The bus communication controllers (also known as bus communication control chips) used in communication are basically designed according to the working mode of synchronous communication, and are mostly used in industry. This parallel interface bus communication controller has the characteristics of fast data transmission speed, strong anti-interference ability, strong fault tolerance function, high reliability, and can work in harsh environments. However, the production cost of this bus communication controller is relat...
