Everybody help, about the question of the mouse

The working principle of the scroll wheel mouse is: there is a ball that can roll freely at the bottom of the mechanical mouse, and two internal encoder rollers that are supported at an angle of 90 degrees are installed in front of the ball and on the right, and when the mouse is moved, the ball rolls with it, and the encoder roller next to it will be driven, the front roller represents the forward and backward sliding, the right roller represents the left and right sliding, and the two axes moving together represent the non-vertical and horizontal sliding. This allows the encoder to recognize the distance and orientation of the mouse movement, and generates a corresponding electrical signal that is transmitted to the computer to determine the correct position of the cursor on the screen.

If you press the mouse button, the number of times you press and the position of the cursor when you press it will be transmitted to the computer. After receiving this signal, the computer and software can work accordingly. Among them, there are two forms of mechanical mouse encoder: organic and photoelectric.

Electromechanical encoders use mechanical contact contacts, which are low accuracy and easy to wear. At present, a large number of optoelectronic encoders are used, and such mice are often referred to as opto-mechanical mice.

The other type is the photoelectric mouse, which works by using a special grating plate as a displacement detection element, and the distance between the upper compartments of the grating plate is. There is a light-emitting element and two focusing lenses inside the mouse, and the emitted light is focused by the lens and shoots down from the small hole at the bottom, illuminates the grating plate under the mouse, and then reflects back into the mouse. When the mouse is moved on the grating board, because the light and dark stripes on the grating board have a change in intensity, the reflected light with the change in intensity will be turned into an electrical pulse inside the mouse, and the distance of the mouse can be measured by counting the electrical impulses.

The photoelectric mouse must be used on a special board, and the range of movement is limited, but its positioning accuracy is high, and the dustproof performance is good, which is conducive to engineering drawing, but it is more expensive.

In addition, there is a mouse called a "trackball", which works on the same principle as a mechanical mouse and has a similar internal structure. The difference is that when the trackball works, the ball is on top and directly dialed by hand, while the ball seat is fixed. Therefore, the trackball occupies a small space and is mostly used in portable computers.

The trackball has two buttons, one for the user to click or double-click, while the other provides the action needed for selecting the menu and dragging the object.

Mainly rely on IO control chips.

The middle button is the scroll wheel, and the right button is sliding? How do you slide the right button? Kind of don't understand.

Let's talk about the solution.

1.Take a look at the mouse options in the control panel, and whether you have selected the main button and the secondary button. If there is, cancel it. After removing it, see if the mouse is normal or not.

2.If it's not normal, borrow someone else's mouse to try it, if someone else's mouse is normal, it's caused by the wires inside the mouse.

3.If someone else's mouse is like this, it may be caused by installing some software, look at the settings from the boot startup item, cancel all the things you don't need, and don't let them participate in the startup.

4.If it's not good, you'll have to redo the system.

Double-click with the left mouse button.

There are four workarounds.

If it's just stealing food from the Internet or something, this thing is enough.

2. After-sales: Generally speaking, regular manufacturers have at least 1 year warranty, and generally warranties can be taken with invoices and complete packaging.

3. Repair: If the electrician is good, directly disassemble the mouse, replace the left button micro movement and the side button middle button micro movement, or disassemble a usable micro motion welding from other poor mice.

If the electrician is not good, go to the pharmacy and buy a bottle of anhydrous alcohol (about 10 yuan, which is not expensive).

Then take the mouse apart, and soak the circuit board and micro switch in the left button directly with alcohol for half an hour (you can press the micro movement to let the inside fully contact the alcohol) ......Then dry in the shade for a day or so, and put it back on.

It can temporarily solve the problem for a period of time (depending on the character, according to the results of my experiments, sometimes it can be solved at one time, and some can be solved on the spot within a few hours, and this situation can only be changed to micro-movement).

4. Buy new ones.

Don't explain it......

Don't explain it. There is a question to ask the question point.

Please take Kena.

1. First of all, you need to find and right-click the name of the "menu" button, and then you need to find and click the name of the "run" button at the bottom of the drop-down menu that pops up next, enter the "control" command in the pop-up page box, and click the "OK" button

2. Then you need to count your pants in the next pop-up "Control Panel" page box, find and click the button named "File Explorer Options".

3. Finally, you only need to check the "Open project by double-clicking" option to solve the problem that the left mouse button often turns into a double-click
