Referring to fig. 7, in one embodiment, in step S150, changing the physical address of the DIO interface according to the state information configured for the DIO interface and the mapping relationship between the preset state information and the address information includes:
Step S151: and obtaining a virtual memory address distributed by the Windows system according to the physical address of the DIO interface.
In general, the Windows operating system manages the physical addresses accessed by application program processes by using a virtual memory management technology, each process is allocated with a 4GB virtual address space, and the virtual address space of each process is divided into a null pointer assignment partition, a user mode partition, a 64k forbidden partition and a kernel mode partition depending on the bottom layer implementation of the operating system; the null pointer assignment partition is used to help a programmer capture assignment of a null pointer, and cannot be assigned, accessed or used by a program dynamic memory allocator, and if a thread in a process tries to read or write a memory address located in the partition, an access violation is caused. The user mode partition is that all exes and dynamic link libraries in the Windows operating system are loaded into the region, and accessible resources of the process are loaded into the region. The purpose of the 64k forbidden partition is to isolate the user mode partition from the kernel mode partition, preventing user programs from crossing into kernel space. Kernel mode partitioning is where code resides for an operating system; the code for threads, memory management, file systems, network support, and driver related programs is loaded into this region, which is common to all processes. The physical address of the DIO interface is located in the kernel area, and the operation needs to be performed on the kernel address to change the state of the physical address of the DIO interface. Specifically, after the physical address of the DIO interface is obtained, the system of the electronic device uses the physical address of the DIO interface as a virtual memory address, and at this time, the virtual memory address can be directly changed.
Step S152: and changing the virtual memory address according to the state information configured for the DIO interface and the mapping relation between the preset state information and the address information.
Step S153: and calling a kernel driver to change the physical address of the DIO interface according to the changed virtual memory address and the preset mapping relation between the virtual memory address and the physical address of the DIO interface.
After changing the virtual memory address, the physical address of the DIO interface may be synchronously changed, and mapping between the virtual memory address and the physical address of the DIO interface needs to be established, specifically, a kernel driver is loaded by calling a function ZwMapViewOfSection () provided in a system core file ntdll, and the kernel driver is notified of which virtual memory address the mapped address is specific, so that mapping between the virtual memory address and the physical address of the DIO interface is established, thereby changing the physical address of the DIO interface.
According to the embodiment of the application, the configuration of the DIO interface configuration interface to the state information of the DIO interface is realized through the mapping relation between the preset state information and the address information and the mapping relation between the preset virtual memory address and the physical address of the DIO interface, so that the physical address of the DIO interface can be configured, and the configuration of the DIO interface is realized rapidly.
Referring to fig. 8, in one embodiment, the address information includes address bits that need to be changed and values on corresponding address bits; in step S152, changing the virtual memory address according to the mapping relationship between the state information configured for the DIO interface and the preset state information and address information includes:
Step S1521: and determining the address bit of the virtual memory address to be changed and the value on the corresponding address bit according to the state information configured for the DIO interface and the mapping relation between the preset state information and the address information.
For the state of the DIO interface, the state change can be realized only according to the values of the main board model on certain address BITs, for example, for the main board model CIS-RKBU-LW01, if the DIO interface is to be changed into the input state, the values of the address BITs of the 0 th BIT, the 1 st BIT, the 8 th BIT and the 9 th BIT of the DIO interface are only required to be changed into x, x,1,0 respectively, that is, the change BIT [9,8,1,0] =value [0,1, x ] is set, and the DIO interface can be changed into the input filling.
Step S1522: and changing the virtual memory address according to the address bit which needs to be changed of the virtual memory address and the value on the corresponding address bit.
According to the embodiment of the application, through the preset mapping relation between the state information and the address information, the automatic change of the address can be automatically realized according to the state information configured for the DIO interface.
In one embodiment, the DIO interface configuration method based on the Windows system may further include the following steps:
step S160: calling a kernel driver to read the configured physical address of the DIO interface;
Step S170: acquiring the state information of the DIO interface according to the physical address of the DIO interface and the mapping relation between the preset state information and the address information;
Step S180: and displaying the identification information of the DIO interface and the state information of the DIO interface on the main control equipment.
After the display is completed, the kernel driver is unloaded through ZwUnmapViewOfSection () to reduce the memory occupation.
Referring to fig. 9, after DIO Port1 is input in the DIO interface identification information input box and the output high-level state trigger button is clicked, the DIO Port1 is configured, and then the DIO Port1 is configured successfully and the current state of the DIO Port1 is fed back in the DIO configuration interface.
According to the embodiment of the application, the configured physical address of the DIO interface is read, so that the state information of the DIO interface is fed back, and a user can learn the current configuration condition of the DIO interface in real time.
