Abstract
The invention discloses an IO (input output) communication method, and relates to the technical field of communication of hardware equipment. The IO communication method comprises the following steps: A, encapsulating a read-write operation of the hardware equipment into a standard performance function; B, compiling the encapsulated performance function into a dynamic link library; and C, loading the dynamic link library and invoking the performance function in the dynamic link library so as to realize communication with the hardware equipment. The invention provides a set of normative function interface standard, which encapsulates the communication method of specific hardware equipment into a plugin invoked during the communication of the hardware equipment, can realize the invoking of an external application on hardware IO, and is unrelated to a specific communication protocol; and by adopting the IO communication method, a unified communication interface which is unrelated to a hardware transmission protocol can be provided for access and control of the hardware equipment.
