Hi Norbert,
ich habe eine alte USB Kugelmaus (NoName) versucht, wie es weiter unten schon angesprochen wurde. Auch auf einem Nano Klon lief es problemlos. Evtl. muß man die Datenleitungen tauschen. Bei mir war Data+ das Clock Signal, und D- dann die Datenleitung.
Es kann also auch mit alten USB Mäusen gehen. Wollte ich nur mal mitteilen. Danke für Deine Projekte. Die sind wirklich eine große Hilfe. Schöne Grüße.
Me: Danke für den Hinweis. Ja, die alten USB-Mäuse waren oftmals PS/2-Mäuse mit USB-"Ubersetzer".

Hi Norbert,
I tried replicating your optical_mouse project with the Mouse/M-SBF96 from Logitech, which contains the ADNS2610 I believe. For my first attempt, I soldered the Data,clock,Vdd and ground directly onto the cables of the mouse. That didn't really work, because the mouse wasn't even able to initialize. For the second attempt, I soldered the four cables to the appropriate connections on the sensor itself. Now the values change even if the mouse isn't moving.
Me: I only checked that code with an old mechanical PS/2 mouse. Did you use an Arduino UNO? To what pins of what chip did you solder the cables directly? Some photos of your project could be helpful.

Download file: "computer-mouse.zip"
Folder: "optical_mouse"
Routine: "optical_mouse.ino"
Besides, the variables in question in your routine are "x" and "y". ("mx" and "my" are the names I gave to them, so I think you should also need to guess this from the previous comment.) I'm sorry, please don't get mad. Thanks for you time.
Me: Now I see what you were talking about (without getting mad). Yes x and y are char and so limited to one byte and so ranging from -127 to 127. That's the definition according to the ps/2 protocol and so can't be changed (because the firmware on your mouse won't recognize that change). Its the movement since the last read happened. The only solution is to read in intervals short enough to prevent an overflow from happening before the next read starts.

Hello Norbert.
Thanks so much for your "computer mouse" routine. It is being very useful to me!
I'm trying to use the ps2 mouse to track the motion an unbalanced wheel (a pendulum wheel).
Everything goes fine unless for one thing: "mx" and "my" are limited between -127 and 127. My question is: could I do something to release such limitation? (I wonder this happens because the char varible type, but I'm not sure how to modify it).
Thank you very much in advance!
Best wishes
Me: People tend to think I could always remember each line of all code examples on my pages. The truth is: I can't.
So please say exactly what download file (and subfolder of the packages) you are talking of.

Thanks for the great article.
There are cheap adapters to convert USB mouse to PS2. They simply connect Data+ and Data- lines of the USB to Clock and Data lines of PS2 connector.
So can we do the same to connect a USB mouse to Arduino by connecting those D+ and D- lines to Arduino pins 5 and 6?
Me: All I can say is: try it out and leave another comment if it works with your mouse model. Most, but not all PS/2 mice work with the Arduino software I am using. The chance is higher, the older or the more simple the mouse model is. The super dooper features mice often have extensions to the protocol that cause trouble and so won't work with the simple implementation on the Arduino.

Greetings, Norbert.
I did a replication of your setup. Got permanent x=0, y=0. Please, advise, what means the stat = 1000 (binary), which is also always the same. I'm trying to capture the pulses train on data analyzer. Please, advise the data configuration, 8N1 or something else. What about MSB (most significant bit) first, or LSB first?
Me: What setup exactly? I have made more than just one. Would also be nice to have pictures of what you have built. My mail address is in the column contact.

In the same sketch I see useless 36 line. Nevertheless of condition being true or false nothing then happens.
Me: That line
while(digitalRead(PS2CLOCK)==HIGH);
means the Arduino waits (does nothing) until the pin PS2CLOCK goes LOW. It is an absolute essential line.

Hello!
In "Optical mouse" sketch review 14-17 lines. The pin "pin" declared as INPUT, then toggled to HIGH as OUTPUT.
Me: If set to input and then doing a digitalWrite(pin, HIGH) activates the internal pull-up resistor of the Arduino.

(From your "computer mouse" page) I finished my arduino 4WD car project (with arduino nano), I want to add a spcp168a chip readings, I managed to turn it on with vcc +5 and gnd, but I don't know if the pins are correct, i connected 2 as PD, 3 as SD and 4 as SCLK ... Can you see the datasheet? (Please)
http: //datasheetcafe.databank.netdna-cdn.com/wp-content/uploads/2015/11/SPCP168A.pdf
If they are correct, is the data reading different? how would it be?
Thank you.

Me: There is more than just one mouse project on that page. You must tell me EXACTLY what sample codes you refer to and what reading you want to get. X/Y coordinates or do you want to play with the camera hack of the optical mouse?

Hi,
First of all, Thanks for this, it alredy helped me a lot with my school project(ofc im giving you the credits you deserve)!
Now i can get the vector position and so the abs position of the mouse in a 2d coord.
Im trying to 100 understand the code.
Im not really sure how the read/write process happens do it read/write a 8 bit mask?
In the mouseInit, why do you pass 0xFF and 0xF0 to the Write()
I would really appreciate your help, although you alredey helped me a lot!
Vielen DANK!
Me: Since I have written more than just one mouse project it's always a good idea to tell me exactly what file (download package, included folder, code line et cetera) you are talking about.
I guess you are talking about the optical mouse connected to an Arduino (computer-mouse.zip optical_mouse). It is indeed transmitting and receiving 8-bit data and passing special characters is required because of the PS/2 protocol the mouse uses for transmission. Details about that protocol are available at: https://isdaman.com/alsos/hardware/mouse/ps2interface.htm.
Nice to see that I am back in school - somehow ;)
Bitte gerne!

Hi
I'm looking for a device can 3d printing and PCB milling It should cheap. Can you suggest me one. Or do you sell your devices?
thanks.
Me: 3D printers don't have to fight sideloads (except inertia), the print head and mechanics must be lightweight. Milling machines must fight sideloads and so need a stiff, heavy mechanics. that's why you'll never find a cheap machine that can do both. I'd suggest buying a 3D printer like one of the Zonestar series and modify it to a milling machine afterwards if you don't expect too much of it (and that's what you never can from what ever cheap machine you buy).

Hi, may I know why do my serial monitor doesn't appeared any numbers?
It said after I load the sketch:
"Sketch uses 3222 bytes (9%) of program storage space. Maximum is 32256 bytes.
Global variables use 241 bytes (11%) of dynamic memory, leaving 1807 bytes for local variables. Maximum is 2048 bytes."
I'm using Arduino Uno for the Data Transmission. And my mouse did compatible with the PS/2.
Can you help me?
Me: So compillation of program and upload succeeded. Did you set the correct baud rate in the serial monitor window? If you would have told me exactly what sketch you are talking about (I have written more than yust one) I could tell you what baudrate to set.

I have added the snippet below to:
computer-mouse.zip :: optical_mouse.ino
in the
void PS2MouseInit(void)
routine.
The PS/2 optical mouse is made by Cherry and has a 8-pin sensor.
Thanks again!
Me: The question is if this mouse supports different physical resolutions and if the bytes you send are actually the right ones. Standards are sometimes weirdly implemented, that's also true for PS/2 communication...

Hi Norbert,
I have hoked up a PS2 mouse to an arduino, and the readout works, but I am unable to change the mouse-resolution by adding the following code to setup():
PS2Write(0xE8)_ //set resolution
PS2Read()_ //We receive a code 0xFA
//adding delay $here doesn't help
PS2Write(0x00)_ //resolution 1 counts per mm is requested
PS2Read()_ //We receive a code 0xFA
delayMicroseconds(100)_
Any idea what may be amiss? Did changing the resolution work for you? Thanks!
Me: I did not play with the resolution. Can't give a better answer as long as you don't say exactly what software package you are talking about. I have used more than one example on my pages...
Probably your mouse doesn't support changing resolutions that way.

i did your coordinate project. its working fine. but i dont want to read delta x or delta y. i want to read actual position .for example this is on my comport monitor:
11000 delta X=-1 delta Y=1
11000 delta X=-1 delta Y=0
1000 delta X=0 delta Y=0
1000 delta X=0 delta Y=0
11000 delta X=-1 delta Y=2
11000 delta X=-1 delta Y=0
its getting zero when i stoped to movement. i want to read coordinates like on your optical encoder project. which part of codes should i change ?

Me: I am very confident you understood something of the source code - which package exactly are you talking of? (I have written more than one example code). So read it again and ask more specific questions about it - that's the only kind of help I can offer.
