The a2l file parsing unit 24 retrieves the corresponding variable name from the data segment parsed by the variable name member-to-address mapping file in the already assigned structure variables and reads the address thereof.
The data segment information search unit 25 writes the address corresponding to the variable parsed from the corresponding data segment into the address member of the corresponding structure variable. The data segment information searching unit 25 judges the attribute of the structural variable, if the attribute is the calibration quantity, calculates the offset of the address according to the address of the structural variable in the RAM and the mapping address of the calibration data segment in the flash/ROM, and writes the offset after subtracting the offset from the mapping address, if the attribute is the measurement quantity, the offset is directly written after the address conversion is not needed.

Wherein the head and tail templates comprise: macro definition, data segment name and address definition, daq list definition, and calculation method definition. The parameters of the memory space segment related to the controller can be obtained from the previous user configuration information and address mapping file.
Referring to fig. 4 and 5, the automatic generator module 2 performs the following steps.
And reading the address mapping file under the specified path in a stream file mode according to the address mapping file label input by the user, and carrying out character string processing and reading and writing so as to retrieve and acquire the needed data segment information.
And reading the stream file of the application variable database file (. A2l) generated by matlab under the specified path of the user, processing and searching the character string, wherein the main key word is ASAP2 protocol, and then distributing all information to the corresponding structural members in the specified elements in the corresponding type of structural array according to the definition form of the structural body.
The default part of the content of each member of the structure is searched by processing the members of the structure, and the variable name, namely the variable name member in the structure, is searched in the data segment read from the corresponding address mapping file, and the corresponding address or related information is filled into the variable member of the structure with the corresponding attribute after the search is completed.
In retrieving and writing address variables, it should be noted that if a nominal amount, its RAM should be written to the address that maps to its corresponding Flash/ROM. The address is required to be converted, the RAM address of the standard quantity is read out firstly, then the base address of the standard quantity data section in the RAM is subtracted to obtain the corresponding address offset of the standard quantity in the variable standard quantity data section, and the base address in the standard quantity data section hybrid ROM is added to the offset to obtain the address of the standard quantity in the actual ROM/Flash.
By means of the data management mode of using the structure body array and the structure body members thereof, parameters of various types of variables can be managed and distributed more effectively, so that the software is easier to maintain and respond to new requirements of users, such as parameters describing the variables for a computing METHOD COMPUTE METHOD, upper and lower limit values Upper Limit Lower Limit of the variables, a variable alias Long Identifier and the like.

FIG. 6 illustrates a flow chart of an embodiment of a user configurable method of automatically generating a2l files of the present invention. Referring to fig. 6, the detailed steps of the method of the present embodiment are as follows.
Step S1: and carrying out universal predefined configuration on the a2l file to be generated through a user configuration interface, and assigning configuration items to corresponding program data interfaces.
And acquiring paths of an application layer variable database file (.a2l file) generated by matlab and an address mapping file of memory data generated by a compiler through a user configuration interface, and simultaneously acquiring a tag name in the address mapping file configured by a user as an interface.

Step S3: and the automatic generator reads the stream file of the a2l file generated by the matlab under the specified path of the user, processes and searches the character string, wherein the keywords are distributed to the corresponding structural members of the specified elements in the corresponding type of structural array according to the definition form of the structural body according to ASAP2 protocol. Wherein the structure body comprises: a calibration volume structure, a measurement volume structure, a Y-axis calibration volume structure, and an X-axis calibration volume structure.
Step S4: the automatic generator searches the default part of the content through the processing of the structural member, searches the variable name member in the structural member from the data segment read from the corresponding address mapping file, and fills the corresponding address or related information into the structural variable member with the corresponding attribute after the searching is completed.
The method further comprises the following steps: judging the attribute of the structural body variable, if the attribute is the calibration quantity, calculating the offset of the address according to the address of the structural body variable in the RAM and the mapping address of the calibration data segment in the flash/ROM, subtracting the offset from the mapping address, writing the offset, and if the offset is the measurement quantity, directly writing the offset after the address conversion.
Step S5: and writing the head template and the tail template for the new a2l file, circularly writing the members of the structural variables into the appointed section definition of the pre-portable a2l file according to the standard format of the a2l file, and outputting the file to a path appointed by a user.
Referring to fig. 4 and 5, the method of the present embodiment is as follows.
Before the user generates the variable database file (. A2 l), some feature options may be manually configured to ensure that the output a2l file can run on a different controller platform. The address mapping file (. Map) path and the variable database file (. A2l) path generated by matlab are necessary configuration items, and the automatic generator module needs to access the corresponding file according to the path and perform the read-write operation of the stream file on the file. The measurement data segment names and addresses and the calibration data segment names and addresses are optional configuration items, and if the user configuration items are empty, the generator generates according to default configuration (the default configuration is the link file definition of the mpc5604 singlechip of the POWERPC).
The operation interface of the user configuration interface under the Windows system is shown in FIG. 3, and when the user configuration is completed, the automatic variable database file (. A2l) is generated by clicking the generator key. Wherein the data segment labels and start addresses in each selectable configuration item are defined in a lcf link file in the engineering source file, and the user can modify the configurable items according to the determination of the data segments in the file by different controller platforms.
When the user clicks the Generate key in the configuration interface, the device will launch the auto generator module to perform the following steps.
Calling the data of each data section interface in the user configuration interface, namely the name of the calibrated data section, the name of the measured data section, the starting address of the calibrated memory and the starting address of the calibrated memory, and storing the data in a cache in a character string format for later program retrieval. The declaration of the data needs to be public, so that the user can modify the content configured in the text box, the initial values of the declaration are all default values applicable to POWERPC 5604B, and if the configuration item in the text box is empty, the program runs according to the default values.
Four structural body types are defined: the structure type of the standard quantity, the structure type of the measuring quantity, the structure type of the array type X-axis standard quantity and the structure type of the array type Y-axis standard quantity. The definition rules are defined in the format of the definition of variables by the matlab generated variable database file (.a2l). The members of the structure were measured in the general definition order of the structure: variable name, long id, type, conversion mode, resolution, precision, upper limit, lower limit, memory address. The members of the standard volume structure are: variable name, long id, calibration quantity type, memory address, record format, conversion mode, upper limit value and lower limit value.
Examples of creation stream files and read stream files of the user-defined file path construction address map file (.map) and variable database file (.a2l) are accessed.
And (3) address mapping file processing, wherein the read map file character string is searched according to a label name configured by a user, and the calibrated quantity data segment information and the measured quantity data segment information are obtained, and the content of the data segment information comprises: variable name, data type, memory start address, occupied space, belonging source file, etc. And acquiring key data segment information by a method of intercepting character strings, and storing the key data segment information according to an original file format of the key data segment information.
The source variable database file (. A2 l) generated by Matlab is processed, firstly, the read-in file is divided into a data definition block according to each/begin to/end according to definition keywords, and the content in/begin CHARACTERISTIC to/end CHARACTERISTIC is defined as the calibration quantity, wherein the calibration quantity is divided into two types: if the/begin AXIS_DESCR key is searched in the data block, the data block is judged to be the Y-AXIS standard quantity, and the rest is the general standard quantity. The key labels of the MEASUREMENT data blocks are/begin MEASUREMENT and/or end MEASUREMENT. The key labels of the array type X-AXIS calibration data block are/begin AXIS_PTS and/end AXIS_PTS. And allocating the elements in the corresponding structure body array to each data block according to the type of the data block.
After being allocated to the corresponding structure body array element corresponding to the data block type, the contents in the data block need to be filled into the members of the corresponding structure body array element according to the attribute type. The general format is to divide a data block by a line-break according to the line-break as a separator, and write the attributes describing this variable one by one into its members in the order of the circular division.
After filling in the structural members, the content in the structural members needs to be processed by character strings, and the annotation is added before the available data in the version generated by matlab, so the character strings need to be processed and the data which can be used directly finally is rewritten in the structural members of the type where the character strings are located. The variable database files (.a2l) generated here because of matlab all follow a column aligned format. Only one unified deletion of the content from index 0 to 40 characters is required here, with the remaining characters being written as valid data into the structural members.
And searching the corresponding address information in the corresponding type data segment acquired by the address mapping file by taking the variable name member of the structural member which has been written with the data as the key word of the index, and writing the address information into the corresponding structural member after intercepting the address information, wherein the operation of intercepting the address can also carry out a substring function on the character string according to the unified format of the address mapping file.
If the variable is the standard quantity, the address is processed, the obtained address in the memory is subtracted by the initial address in the memory to obtain the offset of the variable in the data segment, and the offset is added with the address of the standard segment in the FLASH/ROM, namely the address of the variable in the FLASH/ROM. Writing the converted address into the address member in the structure.
Constructing a new file instance and an instance of a write stream file under the address mapping file path specified by the user, writing the head and tail templates of the new variable database file (a 2 l), comprising: macro definition, data segment name and address definition, daq list definition, and calculation method definition. The parameter generator related to the memory space segment and the controller can be automatically obtained from the user configuration information and the address mapping file.
And traversing each structure body array and member, writing a newly generated variable database file (a 2 l), wherein the written position is before indexing of the search key word/end MODULE.
Finally, a statement for all the variable names of the standard quantity is required to be added, and the variable name members of all the standard quantity structures are inserted at the end of the file, namely between the keyword labels/begin REF_ CHARACTERISTIC and/end REF_ CHARACTERISTIC.
And resolving all the instances to release the memory, and calling a generated information window to prompt the user that the variable database file is generated completely. At this time, the file will be stored under the address mapping file (. Map) specified by the user, that is, it is generally convenient for the user to use and manage under the bin directory of the engineering original file.
The device summarizes and abstracts the differences and the particularities of each platform on the basis of the current general special variable database file (. A2 l) file generation tool (only aiming at a single controller platform), opens user configurable options as a borrow, and can support the generation of a2l files on different platforms.
