Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment one
Inventive embodiments one propose a kind of implementation method of hardware resource dynamically distributes.As shown in figure 1, the embodiment of the present invention
One method includes：
Step S1, receive using instruction when, judge whether support application instruction, be then execution step S2, otherwise return lose
Lose.
Step S2, an at least application function object is created according to application instruction, it is as shown in Figure 2 realize UART and SPI it
Between data interaction functional object 5, realize between CAN and UART data interaction functional object 6 and realize between CAN and SPI
Data interaction functional object 7.The embodiment of the present invention one is first carried out making code at the beginning of the overall situation, instantiates a USB class object pair
Corresponding data is sent in instruction is received from PC or other equipment platforms, bulk circulation is then entered back into and is waited PC ends upper layer application
Instruction, and according to one or more application function objects of corresponding Command Exampleization.
Step S3, at least hardware capability object for creating the application function object association, USB as shown in Figure 2 connect
Data subobject 11, CAN is received and sends to receive and send the reception of data subobject 12, UART and send data subobject 13, SPI
Data subobject 14, timer counter is received and sent according to device function subobject 15.
Step S4, according to the hardware capability object be the application function object distribute hardware resource, by the hardware
Resource performs the application instruction.Hardware resource USB controller 21, timer conter 122, timer conter as shown in Figure 2
223rd, asynchronous serial communication interface 124, asynchronous serial communication interface 225, CAN BUS controllers 126, CAN BUS controllers
227th, SPI controller 128 and SPI controller 229.The hardware resource of particular hardware functional object and which entity in requisition for
See the hardware resource that applied function module is distributed after building（Need distribution asynchronous as UART receives and send data subobject 13
Serial communication interface 124, asynchronous serial communication interface 225 are, it is necessary to know whether the hardware resource is occupied）.Work as caller
When functional module builds object factory structure applied function module, alloc_dev functions can be called, retrieve unused hardware money
Source, and the type and ID of hardware resource are passed into applied function module, then it is delivered to the associated hardware of application function object
Functional object, just the related register of the above-mentioned hardware resource of making and data structure, complete the distribution of hardware resource.
Step S5, the release hardware resource.When application function object is destructed, associated hardware work(is recalled
Energy object carries out the release of hardware resource（Including impeding shutdown, a series of resources related to the hardware such as clock closing）, so
The free_dev power functions that caller functional module is built in factory afterwards complete the resource release of equipment manager（Will set
Standby middle alloc_states indicates removing）.Hardware resource so is distributed when each application function object builds, is being answered
When release with functional object, occupancy of the release to hardware resource.Need to share when there are more than two application function objects
When same type of hardware resource（Data interaction functional object 5 between such as UART and SPI, realize CAN and UART it
Between data interaction functional object 6 be required for using UART controller）Just can complete logical to asynchronous serial according to equipment pipe and device
Letter interface 124, asynchronous serial communication interface 225 are allocated.If also one applied function module also needs to use UART moneys
Source, then when alloc_dev functions are called will fail, represent resource oneself take, only when before take hardware money
This new applied function module could again after a certain application function object in source releases corresponding hardware resource
It is assigned to hardware resource.
Wherein, related code section is as follows：
In the embodiment of the present invention one, by the hardware resource in the presence of structure management system, by using class
The concrete function realized the need for concept management particular hardware resource；One equipment manager is built by using structure, is used
Equipment manager, the hardware resource of all presence in maintenance system.Realization dynamically freely distributes hardware resource, and can be in program
It is any to increase the applied function module for needing in module, without changing device-dependent code.And need not operate and be
The support of system, the autonomous distribution for completing hardware resource, efficiency of code execution is high, and real-time is greatly improved.Due to that need not operate
The support of system, the space that code needs is small, it is necessary to the FLASH capacity requirements for preserving code are not high.The nothing of the embodiment of the present invention one
Need as operating system, it is necessary to familiar complicated system model, as long as change can just be applied in bare machine system slightly.

Including judge module 10, the first creation module 20, the second creation module 30, distribute module 40 and release module 50.Judge module
10 are used to receive during using instruction, judge whether to support that the application is instructed, and be, performing basis by the first creation module 20 should
An at least application function object is created with instruction, failure is otherwise returned.First creation module 20, for being instructed according to the application
Create an at least application function object.The data interaction functional object 5 realized between UART and SPI, realization as shown in Figure 2
Data interaction functional object 6 and data interaction functional object 7 between CAN and SPI is realized between CAN and UART.It is of the invention real
Apply example one and making code at the beginning of the overall situation is first carried out, one USB class object of instantiation refers to for being received from PC or other equipment platforms
Order sends corresponding data, then enters back into the instruction that bulk circulation waits PC ends upper layer application, and according to corresponding Command Example
Change one or more application function objects.
Second creation module 30, creates an at least hardware capability object of the application function object association；As shown in Figure 2
USB receive and send data subobjects 11, CAN and receive and send that data subobject 12, UART is received and to send data right
As 13, SPI receives and send data subobject 14, timer counter according to device function subobject 15.
Distribute module 40, for being that the application function object distributes hardware resource according to the hardware capability object, by
The hardware resource performs the application instruction.It is hardware resource USB controller 21 as shown in Figure 2, timer conter 122, fixed
