Case.
The present inventor is in product development according to the difficulty that runs into, it is contemplated that considers the selection of device production manufacturer
The design of hardware and software of multifarious resolution policy, i.e. some device should be able to compatible multiple chip production manufacturers, multiple hardware moulds
Manufacturer is organized to ensure that product can select the high performance-price ratio device producer that price is lower, quality is more excellent, delivery cycle is more stable.
The first embodiment of the present invention is related to a kind of device compatibility method, applied to embedded electronic product, specific stream
Journey is as shown in Figure 1, comprise the steps of：
Step 101, establish the identity information of device and driver preserves the mapping table of address and preserved.Wherein,
In the mapping table, each identity information corresponds to a driver and preserves address.In this step, can be by common difference
The address of the driver of identity information device and the identity information of device are associated, and are preserved in the mapping table.Need
Bright, which can also be updated according to actual needs.
In the present embodiment, the identity information of device includes the identity of chip, the identity of hardware and device
Production firm's information.In practical application, the identity information of device can also be the identity of chip, the identity mark of hardware
Know the combination of any one information or any two kinds of information in production firm's information with device.
Step 102, the identity of the chip of recognition means.In the present embodiment, can according to the identification code of chip,
The identity of identification chip.In practical applications, the identity of chip is usually the model of chip, it is, can root
According to the identification code of chip, the model of identification chip.Again since under normal circumstances, a chip manufacturer only produces fixed one kind
Or the chip of several models, as long as identifying the model of chip, it is possible to know the production firm of chip.
For example the device of vendor A, B production is XXX, then the chip model that can be selected by recognition means XXX, area
The manufacturer for separating the XXX of embedded electronic product selection is A or B.
In practical application, the identification code of chip can also include the model and production firm's information of chip at the same time.In short,
In this step, by the identification code of identification chip, it can not only know the model of device chips, can also know chip

Sample, such as the OTP information of E producers burning is MMM, then the OTP information of F producers burning cannot be MMM, can be NNN, as long as
The OTP information of discord E producers is identical.
Step 105, according to the identity of the chip of identification, the identity of hardware and OTP information, the body of device is determined
Part information.
Specifically, on the one hand, such as, it is determined that the model of chip, the model of hardware and device are included in device
Production firm's information, has determined that the identity information of device, can thus determine the driver of device.On the other hand, than
Such as, in 2 devices, chip, the hardware of different model of different model can be used respectively, is grown up to be a useful person in the assembling of same manufacturer
Part, but chip, the hardware of same model of same model can also be used, and device is assembled into by different vendor.So as long as
It can determine the identity information of device, it is possible to which the device of compatible more production firm's productions, reduces embedded electronic product pair
The dependence of device manufacturer.
Step 106, according to the identity information of definite device, from mapping table, the corresponding driver of device is found out
Preservation address.Wherein, the identity information of the driver of device and device preserves in the mapping table correspondingly.When knowing
During the identity information of device, the preservation address of the corresponding driver of device from mapping table, can be found out.Inquired about according to table,
It is simple and convenient.
