Specifically, because the PE developer provides a Dynamic Link Library (DLL) of the burner, the embodiment of the present application may use the calling Library function node to control the burner to burn the to-be-burned automobile electronic module. The dynamic link library is relative to the static link, is a file which allows a program to share and execute a special task, can enable a process to call a function which does not belong to executable codes of the program, can not be directly operated, and only provides a group of functions for an application program to call.
In order to make those skilled in the art further understand the recording apparatus for an automotive electronic module in the embodiment of the present application, the following describes in detail a recording method related to the recording apparatus for an automotive electronic module in the embodiment of the present application.
First, the function of the library function of the lower burner part is described.
connect _ to _ cycleprep _ by _ ip: the input parameter of the function is a character string type, the function is connected with a burner through an IP address, and the IP address of the burner is set to be in the same local area network with an upper computer. The type of the return value of the function is an unsigned 32-bit shaped value, and each connection generates a special value as an input parameter (cyclonexaxhandle) of other functions, and the connection is failed only when the return value is 0.
update _ image _ with _ file: the function has two input parameters, the function is used for updating the information of the burning File in the burner, one parameter, namely, cyclic _ to _ cyclic _ epromax _ by _ ip function, is the return value of the connect _ to _ cyclic _ epromax _ by _ ip function, and the other parameter, namely, File, is the path of the new burning File. The return value of the data type is a Boolean type in the C language declaration, and the Boolean type has no special data type for transferring between the DLL function and the LabVIEW VI, and can be transferred by using a numerical value type, wherein the return value of the data type indicates that the updating is successful when the return value is 1, and indicates that the updating is failed when the return value is 0.
start _ execute _ all _ commands: the function is to start the burning. Since one burner can store a plurality of burning files, the value of the parameter image _ id needs to be specified, and if only one burning file exists in the burner, the image _ id should be set to 1.
check _ cycleprotamax _ status: the function is used for inquiring whether the burning is finished or not, the return value is 0 to indicate that the burning is finished, and the return value is 1 to indicate that the burning is in progress.
get _ last _ error _ code: the function is used for inquiring whether the burning is successful or not, the burning is successful only when the return value is 0, errors are caused during the burning when the return value is other values, different values represent different error reasons, and a user can search the reasons of the burning failure according to the values.
Next, referring to fig. 2, a program design of the LabVIEW call burner DLL file is described.
The interconnection interface → the library and the executable program → the calling library function node are sequentially selected in the LabVIEW program block diagram, the node is placed in the program block diagram, and a configuration dialog box for calling the library function node appears by double clicking the node icon or right clicking the icon to select a configuration item. Selecting a path of a DLL file library in the library name/path, or checking a path designated in a program diagram, and selecting a function to be called in the function name. The "thread" is used to set in which thread the called function is running, and the default may be selected. The 'calling specification' is used for indicating the calling convention of the called function, stdcall is generally used by the Windows API, Ccall is mostly used by the library function of the standard C, and when the selection is wrong, LabVIEW breakdown can be caused. Next, the parameters of each function need to be set under a parameter tab, the three most commonly used data types for transferring parameters between the DLL and the LabVIEW are numerical values, numerical value arrays and character strings, and the set parameter names and data types are all consistent with the called functions. The settings in the other two tabs remain default.
After the library function node configuration is completed, the corresponding input/output terminal is displayed, and then a connection burner VI is created, and a block diagram of the procedure is shown in fig. 2.
The return value of the connect _ to _ cycleprotamax _ by _ ip function is connected to a branch selector of the conditional structure, when the return value is 0, the connection is failed, at this time, source in an error cluster is assigned with open cycle failed to represent error information, code is assigned with 100000 to represent error codes, and status is respectively assigned with True to represent errors. If the connection fails, the system processes errors and displays error information and error codes; conditional branch 1 is set to "default", meaning that this branch is executed when the return value is other than 0.
As shown in fig. 3, the system hardware related to the recording device of the automotive electronic module mainly comprises an industrial control computer, a recorder, a recording clamp, a power supply (programmable power supply) and the like. When in burning, the inside of the burner can be selected to supply power to the product or the outside can be independently supplied with power, and because the power supply voltages of different products are different, the programmable power supply is selected to supply power to the product; the voltage acquisition module is used for acquiring the voltage of the pin of the automobile electronic module to be burned; the fixed position of the burning clamp is provided with a probe, and the pin of the automobile electronic module to be burned is connected with the pin of the burner after the cylinder is clamped.
