Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a configuration system of an EEPROM (electrically erasable programmable read-only memory) storage interface of a vehicle controller, which is shown in figure 1 and comprises the following components:
the file loading module 11 is used for loading a signal file to be transcoded; the signal file includes a variety of EEPROM signals.
Specifically, a signal file including various EEPROM signals may be input to a designated storage area in the system in advance by a user, so that the signal file in the designated storage area is actively loaded by the file loading module 11 after the system is operated, and is subsequently read.
And a signal reading module 12, configured to read all initial EEPROM signals in the signal file.
It can be understood that the word recognition technology can be utilized, and all initial EEPROM signals are read from the signal file in a keyword extraction mode, so that the EEPROM signals are screened from the signal file; since the EEPROM signals in the signal file may be stored in various types, for example, several types, such as a pool type, a uint8 type, or a uint16 type, when the EEPROM signals are initially read from the signal file, the EEPROM signals still remain the signal types in the signal file, and thus, are referred to as initial EEPROM signals herein to distinguish the EEPROM signals of the subsequent changed signal types.
And a signal type changing module 13, configured to change a signal type that is not supported by the C language in all the initial EEPROM signals into a signal type that is supported by the C language, so as to obtain all the EEPROM signals.
Specifically, in order to enable the EEPROM signals to be stored in the EEPROM in the C language form and to be read and called by the function in the C language form, the non-C language-supported signal type in all the initial EEPROM signals is changed to the C language-supported signal type, so that all the EEPROM signals are obtained, and all the obtained EEPROM signals are the signal types capable of supporting the function reading and calling in the C language form, for example, the uint8 type.
And the attribute extraction module 14 is used for extracting attribute information of all the EEPROM signals.
Specifically, after all the EEPROM signals are read, corresponding attribute information is extracted from all the EEPROM signals, where the attribute information may include a signal name, an initial value, a default value, whether the signal name is a vehicle unique attribute, a signal data type, and other attribute information mutually transmitted by an ASW (application SoftWare layer) and a BSW (base SoftWare layer), and is used for subsequently allocating different storage locations according to different attribute information of each EEPROM.
And a storage space allocation module 15, configured to allocate a storage space of each EEPROM signal in the EEPROM by using the attribute information of each EEPROM signal.
Specifically, the EEPROM includes two storage spaces, one is a space where data is lost after power failure, which is called a removable space, and the other is a space where data is not lost after power failure, which is called an unremovable space, so that it is possible to allocate a storage space of the EEPROM signal in the EEPROM by using whether the attribute information of each EEPROM signal is a vehicle-specific attribute or a signal data type.
And the storage location allocation module 16 is configured to allocate each EEPROM signal and attribute information to a corresponding storage location according to the storage space and attribute information of each EEPROM signal, so as to provide a function call in a preset C language form corresponding to each storage location, and complete configuration of an EEPROM storage interface.
It should be noted that, the configuration of the EEPROM interface may be completed by configuring a function corresponding to the interface function, and different functions correspond to different interface functions, for example, the control interface implements a corresponding storage function for storage, and the control interface implements a corresponding read function for reading, so that if the EEPROM interface is operated in a code in the C language format, only a relevant function in the C language format needs to be configured.
Specifically, after the storage space of each EEPROM signal is determined, the attribute information of each EEPROM signal is allocated to a specific storage location according to the storage space of each EEPROM signal, the storage location may include a cache, a structural body, a fixed storage location, and the like, different storage locations correspond to different functions in the C language format, each function corresponds to a corresponding storage location, the function in the C language format is a pre-generated function template, and by storing the attribute information of the EEPROM signal to the corresponding storage location, the function can read and call the attribute information of the EEPROM signal in the corresponding storage location, thereby assigning the function, obtaining a complete function, and implementing configuration of the EEPROM interface.
Therefore, the embodiment of the invention automatically reads the EEPROM signals in the signal file to be transcoded, extracts the initial EEPROM signals from the signal file, converts the initial EEPROM signals into the signal type supporting the C language form to obtain the EEPROM signals, further extracts the attribute information of each EEPROM signal, distributes the attribute information of each EEPROM signal to the storage space of the EEPROM, distributes the EEPROM signals to the corresponding storage positions by using the storage space and the attribute information distributed by each EEPROM signal to call the function in the preset C language form corresponding to each storage position, completes the configuration of the EEPROM storage interface, realizes the conversion of the EEPROM signals into the codes in the C language form, and automatically completes the automatic configuration of the EEPROM interface, thereby improving the configuration efficiency and accuracy of the EEPROM interface.
