S14: and determining the private driver corresponding to the virtual equipment function by utilizing the second corresponding relation, wherein the second corresponding relation is a one-to-one corresponding relation between the virtual equipment function and the private driver.
It should be noted that the private driver herein refers to the private driver in the prior art; in the prior art, a core processor needs to call a driver corresponding to each function when completing each function.

S15: and determining that the attribute corresponding to the private drive in the virtual equipment instance is an actual input attribute by using a predetermined third corresponding relationship, wherein the third corresponding relationship is a one-to-one corresponding relationship between the private drive and the actual input attribute.
The method for calling the private drive comprises the following steps: inputting attributes corresponding to the private driver to enable the private driver to realize a specific function; and the virtual device instance includes all attributes required for implementing different functions corresponding to the virtual device. Therefore, the actual input attribute corresponding to the private drive in the virtual device instance needs to be determined through the third correspondence.

The virtual device descriptions determined according to core processors manufactured by different manufacturers are different.
For example, for the general input output interface of the STM32F2 family of processors in ST, the private driver provided by ST requires three attributes to be called: port, pin number, and clock driver, then three attributes that define the virtual device description to contain are: port, pin number, and clock drive.

respectively determining attribute actual values of constant attributes contained in virtual equipment description when different private drivers operate the same hardware equipment according to the actual hardware connection relation of a core processor; the external form of the virtual device instance is uniform, but internally has different definitions.
For example, for the STM32F2 series processor in ST, if the PB10 pin under the high speed bus No. 1 needs to be utilized when operating the same hardware device, the device instance is defined to be labeled vgho _1, and the virtual device instance corresponding to it contains the following attributes: PB port, pin 10, high speed bus number 1. In subsequent operation, only the vGPIO _1 is written into the application program, the three corresponding attributes can be determined, and the private drive interface is called by using the three attributes, so that the PB10 pin is controlled.
When the core processor or the hardware connection relation of the core processor is changed, only the virtual device instance needs to be adjusted, and the application program does not need to be changed. In addition, the invention calls the existing private drivers of different manufacturers to realize the control function, thereby reducing the development workload and saving the cost.
