Embodiment Construction

[0044] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of a method for aligning serial port synchronous communication data in the present invention. Such as figure 1 As shown, the method for synchronous communication data alignment of the serial port of the present invention comprises:

[0046] Step S01, the slave sends test data to the master;

[0047] Step S02, the master sends the verification data to the slave after receiving the test data, and waits for the slave to respond;

[0048] Step S03, the slave receives the verification data, and sends a response to the master according to the verification data;

[0049] Step S04, judging ...

Abstract

The invention discloses a method for aligning synchronous communication data. The method comprises the following steps that: a slave sends test data to a host; after receiving the test data, the host sends checkout data to the slave and waits for the slave to respond; the slave receives the checkout data and sends a response to the host according to the checkout data; and when the response is data obtained after the checkout data is subjected to bitwise NOT, the host responds to the response to complete data alignment. According to the invention, by the method, the beneficial effects of rapidly, conveniently and accurately recovering the malposed data and completing data alignment are achieved, wherein in the method, the host reads the test data sent by the slave for twice, a data port is in a high level state and a clock interval is equal to seven clock periods.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for aligning serial port synchronous communication data. Background technique [0002] With the continuous advancement of technology, the hardware architecture of electronic products tends to be more and more connected and communicated between multi-processors, so the data communication method between multi-processors has become the primary problem to be solved. Due to the advantages of fewer communication interfaces and high communication efficiency, the serial bus is favored by the majority of users. [0003] At present, SPI (Serial Peripheral Interface, Serial Peripheral Interface) is widely used in data communication processing between multiprocessors. SPI is a high-speed full-duplex synchronous serial communication bus, which can transmit data at a high speed and reliably under a synchronous clock signal. SPI is divided into two transmission modes, ma...
