Abstract

A general drive system and method for a component serial interface solves the problem that the existing host computer is difficult to drive the satellite component interface, and belongs to the technical field of interface drive. The present invention includes: acquiring configuration information of components to be driven, and determining interface configuration information and protocol configuration information according to the configuration information; interface configuration information includes interface baud rate, byte check information and byte stop bit length; protocol configuration information includes Frame header identification code, frame type identification length, frame type information, frame length and frame check information; set the serial port register according to the interface configuration information; write the data to be sent to the component into the sending register for transmission; use the receiving register Receive the data packet sent by the component, and perform frame header verification and frame type verification on the received data packet in turn according to the protocol configuration information. If the verification results are consistent, continue to receive data frame and data frame verification, otherwise receive a new data pack.

Description

technical field [0001] The invention relates to a serial interface driving system and method, in particular to a satellite component serial interface universal driving system and method, belonging to the interface driving technical field. Background technique [0002] With the advancement of spacecraft productization, more and more components use commercial off-the-shelf components (COTS components), and COTS components mostly use serial interfaces. Since COTS components come from different production units, a unified interface specification or component protocol has not been adopted. , which brings more workload to the realization of the interface driver of the upper computer, and restricts the integration speed of satellite products. Contents of the invention [0003] Aiming at the problem that the existing host computer is difficult to drive the satellite component interface, the invention relates to a component serial interface universal drive system and method. [00...
