The software and hardware version of POS system application apparatus is set with default value, the recognition methods the following steps are included:
Step 1: the POS system reads the default value of each Version Control GPIO pin；
Step 2: the POS system calculates according to the default value of each Version Control GPIO pin and obtains version
Control combination value；
Step 3: the POS system determines the soft of the POS application apparatus according to the Version Control combined value
Hardware version.
Preferably, each Version Control GPIO pin is the POS system application apparatus, automatic except this is realized
Other than the method for identifying software and hardware version, the vacant GPIO pin that is not used in operational process.
Preferably, the quantity of the Version Control GPIO pin is 4.
Preferably, the POS system calculates according to the default value of each Version Control GPIO pin and obtains version
Control combination value, specifically: the described POS system operation version is macro or version function, determines Version Control according to the following formula
Combined value val:val=gpio1 | (gpio2 < < 8) | (gpio3 < < 16) | (gpio4 < < 24) wherein, gpio1, gpio2,
Gpio3, gpio4 are respectively the default value of 4 Version Control GPIO pins.
It is realized based on above-mentioned POS system and starts control method used by the recognition methods of application apparatus software and hardware version:
Step 1: the POS system obtains the soft or hard of POS system application apparatus according to the method for claim 1
Part version；
Step 2: the POS system carries out initialization behaviour according to the software and hardware version of the POS system application apparatus
Make；
Step 3: the POS system application apparatus starting.
Compared with the prior art, the advantages of the present invention are as follows:
It on the one hand, is version due in multiple GPIO pins of the application apparatus processor chips of POS system, there is several pins
This control GPIO pin, each Version Control GPIO pin are set with default all in accordance with the software and hardware version of POS system application apparatus
Value, then in version automatic identifying method, POS system can calculate acquisition by reading the default value of each Version Control GPIO pin
Version Control combined value, and then according to the software and hardware of the determining POS system application apparatus of the Version Control combined value
Version improves the convenience and maintainability of version information reading to simplify existing pure software version differentiating method；
On the other hand, using starting method of the invention, version information can be provided before system is run, realizes differentiated
System start-up initialisation.And POS system application apparatus of the invention realizes the method for version automatic identification and starts method
Implementation is easy, and cost of implementation is cheap, and application range is also relatively broad.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present invention, constitutes a part of the invention, this hair
Bright illustrative embodiments and their description are used to explain the present invention, and are not constituted improper limitations of the present invention.
The step of Fig. 1 is a kind of recognition methods that application apparatus software and hardware version is realized for POS system of the invention；
Fig. 2 is a kind of this practical starting method and step that application apparatus software and hardware version is realized for POS system；
Specific embodiment
Carry out the embodiment that the present invention will be described in detail below in conjunction with accompanying drawings and embodiments, how the present invention is applied whereby
Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
Specific embodiments of the present invention are as shown in Figure 1, a kind of knowledge for realizing application apparatus software and hardware version for POS system
There is POS to handle chip for other method, POS system, and POS processor chips have multiple GPIO pins, have in multiple GPIO pins
Several Version Control GPIO pins, Version Control GPIO pin are set with all in accordance with the software and hardware version of POS system application apparatus
Default value, recognition methods the following steps are included:
Step 1: POS system reads the default value of each Version Control GPIO pin；
Step 2: POS system calculates according to the default value of each Version Control GPIO pin and obtains Version Control combined value；
Step 3: POS system determines the software and hardware version of POS application apparatus according to Version Control combined value.
Each Version Control GPIO pin is POS system application apparatus, except the side for realizing the automatic identification software and hardware version
Other than method, the vacant GPIO pin that is not used in operational process；The quantity of Version Control GPIO pin is 4.
POS system is calculated according to the default value of each Version Control GPIO pin obtains Version Control combined value, tool
Body are as follows: POS system runs that version is macro or version function, determines Version Control combined value val:val=according to the following formula
Gpio1 | (gpio2 < < 8) | (gpio3 < < 16) | (gpio4 < < 24) wherein, gpio1, gpio2, gpio3, gpio4 are respectively 4
The default value of Version Control GPIO pin.
Specific embodiments of the present invention are as shown in Fig. 2, realize the knowledge of application apparatus software and hardware version based on above-mentioned POS system
Start control method used by other method:

Make；
Step 3: the POS system application apparatus starting.
When debugging a serial chip or similar a plurality of products, in order to which management service code is convenient, usually using same
A set of code；And increase the method for control difference version in code by software, and the complexity of code is increased in this way, it is readable
Property and maintainability；And sometimes just need to distinguish version before software difference version function initialization, it is at this moment existing
The function of software difference version just fails in technology.Method of the invention in hardware design phase early period, just plan it is good how
Using GPIO, the default value that each project is fixed to be provided several GPIO PIN foot, and these GPIO are arranged is high or low；It is different
System version, the combined value of GPIO is different, such as: provide 4 GPIO, the default value point of 4 GPIO can be set in we
It Wei 1001,1010,0011 etc.；In software, realize that a function is responsible for specially calculating the combination of the GPIO of control version
Value, can be by calling the function to obtain the combined value of GPIO and judging which system is in system starting process or operation
Version does corresponding different work according to the difference of version.Method to remove complicated software maintenance system version, drop
The complexity of low code, enhancing code readability and reliability, facilitate developer to operate and implement.
The beneficial effects of the present invention are: on the one hand simplifying existing pure software version differentiating method, version letter is improved
Cease the convenience read and maintainability；On the other hand, and POS system application apparatus of the invention realizes version automatic identification
Method and the implementation for starting method are easy, and cost of implementation is cheap, and application range is also relatively broad.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This
Invention is not only limited to above embodiments, and specific structure is allowed to vary.All protection models in independent claims of the present invention
Interior made various change is enclosed to all fall in the scope of protection of the present invention.
