Problems solved by technology

[0004] In the traditional test method, the keyboard test usually only includes test items such as the controller (Controller) and the data line (Dataline), but even if these test items are successfully passed, there is no guarantee that the keyboard can work normally in the actual working environment
Because the test object is only the keyboard itself, and the normal operation of the keyboard is not only related to its own quality, but also related to its cooperation with the keyboard interface of the motherboard and the operating system, and is also limited by the type of hardware equipment.
[0005] The traditional test method can only test the keyboard alone. When it is necessary to test the compatibility between the keyboard and the operating system and other computer hardware devices, it is obviously impossible to achieve. At this time, an integrated test for the keyboard is needed. method to solve the above problems

Embodiment Construction

[0059] See figure 1 , this figure is the general flowchart of the testing method of keyboard under the DOS mode of the present invention, explains as follows:

[0060] First read the raw data file (step 110) of keyboard; Then shield the DOS interrupt program, set up the user interrupt program (step 120); then obtain the scan code (step 130) of the keyboard key in the test execution process by this user interrupt program; Next, compare the scan code with the original data file (step 140); finally output the comparison result (step 150).

[0061] The original data file is the key-value file and key-bit file of all buttons, which is stored as a default file and used as a basis for testing. The steps to obtain it are as follows:

[0062] First screen the DOS interrupt program and create the user interrupt program;

[0063] Then obtain the scan code of each keyboard key through the user interrupt program;

[0064] Finally, the scan codes of the above buttons are stored as a basis ...

Abstract

This invention relates to a kind of keyboard testing method under DOS mode. It can be used for testing the integration of keyboard and its mainboard interface and operation system. The method comprises the following steps: reading the original data file of keyboard; shielding the DOS interruption program; creating user interruption program; getting the key scanning code of keyboard during testing by the user interruption program; then comparing the scanning code and original data file; outputting the comparing result.

Description

technical field [0001] The invention relates to a hardware testing method, in particular to a method for integrating and testing the compatibility between a keyboard, an operating system and other computer hardware devices in a DOS mode. Background technique [0002] The computer has become an indispensable tool in our study and work. To ensure that various equipment of the computer can work normally, it is an important means to conduct various tests on it. Keyboard (Keyboard), as an important computer input device, is responsible for receiving various information input by users, and testing it has become one of the important criteria to measure the quality of a computer. [0003] Under the prior art, there is also the method of carrying out keyboard detection in the mode of Windows, but because the contact with computer hardware is more direct under the DOS mode, it does not need to be contacted with computer hardware after a kind of intermediate layer processing under Wind...
