As you can see at this documentation I collected - including datasheet (there are plenty at Internet), the idea is to use a mouse as a very simple camera, or better, as it has a lot of processing power for image movement detection, use it as a movement sensor, telling if the object has moved on this/that direction, or at a robot if there are objects coming on it's direction and so on, Sun movement, target positioning, etc., etc., etc.
What about to have some positioning routines at your unit? :mrgreen:

Nice idea, I will study the documentation you provided.

If you give me your email address I can send it to you.

Has anyone else also problems accessing http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#USB_HID_Keybd?

many thanks

your site not work?
you need host for your site? i can create a sub-domain in my site.

Normally my site works fine. Perhaps the problem is also something like this: http://www.mikroe.com/forum/viewtopic.php?f=88&t=24911&start=2. Please have a look.

Anyway, thanks for the "host" offer, but for now I do not need it!

i have one problem with USB_PS2_Keyboard
i send caracter $38 = / than pc show ;
i need show ?
but / not work

ps... i changed my dns and your page work 100%

Character $38 is both for "/" and "?". The "?" is the shift version, so in byte 0 of the HID input report you will have to set a "shift" modifier bit (e.g. bit 1 or bit 5).

The modifier bits are:

0: LEFT CTRL
1: LEFT SHIFT
2: LEFT ALT
3: LEFT GUI
4: RIGHT CTRL
5: RIGHT SHIFT
6: RIGHT ALT
7: RIGHT GUI

Glad to hear so.

i try byte 0 = 1 and byte 1 = $38, but show "ç"

Great Dany, as always.... thanks again.

Hi Jose,
I studied the link and what I see is (I hope I am not wrong) ideas about how to use a component that is present in some optical mouses (ADNS-2610). This is of course a total different subject than the thing called "PS2 mouse" (what this unit is about), how interesting it may be of course (and it is...).
So, I propose not to add anything to the "PS2 Mouse" unit because of the possible usage of that component.
At this moment I have no optical mouses that I can destroy for component extraction. Perhaps I will look later deeper into the ADNS-2610 possibilities.

Anyway: thanks for the suggestion!

Indeed Dany, it's a complete distinct usage of the "mouse". Meanwile I will try to define better what would be interesting routines/functions for it.

I see at least 2 main classes. Use it positioning functions and it's "camera". I am seeing some articles in "optical flow", that's the tecnique they use and that is being used for movement detection, objects distance, etc. In some applications you even need distinct lenses...

Hi, a small unit has been added to the website:

TimeBase.mpas (see http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#TimeBase). It permits to measure times (e.g. execution times of codeparts or repetitiontimes of events) in milliseconds (max 65535 = 65.5 seconds) or in seconds (max 65535 = 1092 minutes = 18.2 hours).
Can also be used to make things happen after simply a certain amount of time elapsed.

The principle is simple:
- get a time mark at the start of the measurement
- let the event to be measured execute to closure
- get the time elapsed since the time mark taken earlier

The timing resolution is 1 millisecond, hence the unit has a routine "UpdateTimeBase" to be called by a 1 msec timer interrupt.
Also the program that uses the unit has to define the "TimebaseTimerInterruptBit" variable: the interrupt enable bit of the timer used to call "UpdateTimeBase", e.g.

Code: Select all

var TimebaseTimerInterruptBit: sbit at TMR2IE_bit; // timer 2 is the 1 ms timer used here

A small example project: http://users.edpnet.be/rosseel01/DRO/PIC/TimeBasetest.zip.

Have fun!

Hi all,

The following tools have been updated: the "copy to clipboard" feature has been added. In some cases some other small things have been made better or have been added.

Have fun!

Tool:
RamSizes (v4.1), see http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#RamSizes
RomSizse (v4.0), see http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#RomSizes
Function Calls (v3.3), see http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#FunctionCalls
Global Variables (v4.1), see http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#GlobalVars

Hi,

the "FunctionCalls" tool has been equipped with a graphical representation of the call tree of a selected routine, see http://users.edpnet.be/rosseel01/DRO/PIC/index.htm#FunctionCalls.

Have fun!
