Description
Technical field
The present invention is applied to the identification of product main board version, main board function configuration information identification application technology, particularly a kind of
Method for product software automatic identification motherboard configuration information.
Background technology
In a product platform, same software how to realize the product mainboard of difference in functionality is carried out automatic identification from
And correctly load operating program is a problem having in product development solve.
Existing product software is main real by following 2 kinds of modes on main board version and motherboard configuration information identification
Existing：
1st, made a distinction with different configuration list files：
The mainboard of difference in functionality is made a distinction with different configuration list files, embody in allocation list the version of corresponding mainboard with
And the function information that this mainboard is configured.
This mode manages very inconvenient, needs to be simultaneously introduced this configuration list file in software inventory and carries out one by one
Corresponding, be equivalent to and downloaded software program and also this block mainboard just will can be made correctly to add downloading the corresponding list file that configures of this mainboard
Load program is run.Because the mainboard many kinds of difference in functionality are it is necessary to manage much different configuration list files, such software liter
It is pretty troublesome that level maintenance just seems, obscures when also easily causing production line personnel's download configuration list file.
2nd, it is identified with the varying level state that I/O mouth line common on MCU reads：
This mode is made a distinction using the level state that I/O mouth line can read, and an I/O line can have logic high, patrol
Volume low, hanging three kinds of states are available for configuration and use, and many mouth lines are combined just having enough states and are available for configuration and use.
When this mode is applied, different circuit devcies are carried so that I/O mouth line is in fixing patrolling by I/O mouth line periphery
Collect in level state, first read the level state of configuration I/O mouth line during program loading operation and correspond to it is possible to get this mainboard
Configuration information, thus the correct program of load operating.
As shown in Fig. 1 and table 1, two mouth lines of ICC_SEL3V_5V and ICC_SEL1.8V now by 2 pull down resistor R94,
R99 builds, and makes them be in fixed logic low（LL）State, this mainboard of this status representative is configured with IC-card and SAM card simultaneously
Function, program will automatically identify the card class configuration information of this plate when running.
This mode can realize the automatic identification to main board version and configuration for the software, saves configuration list file, as long as
Upgrade maintenance manages same software.But, a product, in its life cycle, may constantly be upgraded and derive very
Multi version, or a kind of function has several hardware configuration schemes to exist simultaneously and effectively, at this moment individually managed with I/O mouth line
These configurations are difficult to complete.Particularly on the complicated mainboard of some functions, the resource of I/O line is originally very limited, is difficult to
Vacateing the identification that enough I/O mouth lines configure dedicated for main board function, even if the multiplexing of I/O line is also difficult to meet need
Ask.
Content of the invention
It is an object of the invention to overcoming above-mentioned weak point of the prior art and providing a kind of different using ADC collection
The method of voltage, to realize the automatic identification to main board version or main board function configuration information, overcomes single or limited I/O
Mouth line cannot adapt to product version change, and often or a kind of function has the situation of several hardware configuration schemes.
For achieving the above object, the technical scheme is that：A kind of configuration for product software automatic identification mainboard is believed
The method of breath, executes according to the following steps,
Step S01：According to all types of motherboard configuration informations, divide ADC collection voltages numerical value, and create this ADC collection electricity

Step S02：According to the difference of motherboard configuration information, carry different circuit so that leading in mainboard A/D mouth line periphery
Voltage value at plate A/D mouth line is corresponding with this motherboard configuration information；
Step S03：Product software during load operating, reads the voltage value of described mainboard A/D mouth line on mainboard；
Step S04：According to the voltage value of above-mentioned mainboard A/D mouth line, product software is searched described planning table and is obtained this electricity
The pressure corresponding motherboard configuration information of numerical value, thus the further corresponding program of this motherboard configuration information of load operating.
In embodiments of the present invention, described motherboard configuration information is mainboard version information or main board function information.
In embodiments of the present invention, described planning table creates in product software.
In embodiments of the present invention, described step S02, the circuit carrying in mainboard A/D mouth line periphery, including first resistor
And second resistance；One end of described first resistor is connected to power end, the other end of described first resistor through second resistance connect to
Ground；Described first resistor is connected to mainboard A/D mouth with the junction point of second resistance.
Compared to prior art, the invention has the advantages that：
1st, the present invention is relatively more because ADC can gather the voltage value representing, therefore this voltage value can represent more
Motherboard configuration information, to adapt to product version change, often or a kind of function has several hardware configuration schemes；
2 and the present invention solve limited I/O mouth line and cannot adapt to product version change often or a kind of function has
The situation of several hardware configuration schemes.
