Abstract

The invention relates to a method and a processor for controlling digital input and output. The method includes following steps: detecting whether a digital input interface is interrupted or not; when the digital input interface is interrupted, generating a first data packet according to the interruption, and sending the first data packet to a host to enable the same to analyze the first data packet and acquire information of the digital input interface according to an analysis result; receiving a second data packet sent by the host, wherein the second data packet is generated according to a preset function called by the host; analyzing the second data packet; acquiring information of a digital output interface according to an analysis result, and setting the digital output interface according to the information of the digital output interface. By the method and the processor, control functions of the digital input interface and the digital output interface are enabled to be more reliable and diverse; the method and the processor is suitable for various application occasions.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a method for controlling digital input and output interfaces and a processor for controlling digital input and output. Background technique [0002] At present, the digital input and output interfaces commonly used by people are usually realized by the GPIO (General Purpose Input Output) of the X86 platform motherboard. The digital input and output interfaces obtained in this way are usually not interrupted, and the digital input and output interfaces need to be continuously scanned by software. Inputting the interface to obtain information such as level changes not only takes up a lot of software resources, but also easily misses the short-term pulse mutation of a certain digital input interface. In addition, the traditional GPIO has poor scalability, and the control function of the digital input and output interface is relatively simple. Contents of the invention [0003...
