Description
Technical field
The present invention relates to the mouth line identification field of electronic equipment, specifically be a kind of method and device of GPIO mouth line identification equipment version information.
Background technology
In the electronic equipment of prior art, normal to the module that should have different configuration version in a machine, and the drive IC that modules is corresponding different, system CPU needs to know which configuration version is presently used module be when transferring corresponding drive software and making.Traditional scheme uses disparate modules to need to coordinate different software carriers, often occurs the phenomenon that the hardware debug version of various version mixes, is inconvenient to produce and manage, and easily makes mistakes.Therefore, often through the height two states of mouth line, judge the version configuration of disparate modules.During as certain GPIO mouth line display high " 1 ", represent color screen liquid crystal display; When showing low " 0 ", represent screen liquid crystal, different versions is configured for the different liquid crystal drive of system loads.But in the mode of existing use GPIO mouth line identification module version, a GPIO mouth line only has height two kinds of modes, and two mouth lines can only configure 2
nkind of identifying schemes, namely 00,01,10,11, the module release state that can identify is very limited, along with electronic devices structure is more complicated, configure more various development trend, will the demand of very difficult realistic utilization.Therefore, be necessary to provide one can identify more kinds of state, with the method for the GPIO mouth line identification equipment version information of the more module release of correspondence and device.
Summary of the invention
Technical matters to be solved by this invention is: the method and the device that provide a kind of GPIO mouth line identification version information, and solving prior art needs the configuration software carrier corresponding with equipment to carry out identifying or the recognition methods of existing GPIO mouth line can only identify 2
nplant the deficiency of configuration version.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of method of GPIO mouth line identification equipment version information, comprising:
