hello,
Im trying to make a voice activated keyboard. Im trying to send the scan code that a keyboard sends through the ps2 to the CPU by using a microcontroller. can we send the keyboard scan codes using a microcontroller? will the system accept this data? ( when i tried, the system is getting hanged with some beep)
Stuck at that point anyone plz help me...

Yes you can do that and yes a computer will accept the input provided the data is sent in the proper manner. At what point during the boot process or after it are you adding your PIC voice keyboard?

What's MoonTaj.com??

The website doesn't work.

What's MoonTaj.com??

The website doesn't work.

Were you receiving 403 Forbidden? My apologies, this was likely caused by overly broad server security settings. The issue has now been resolved.

 

[Mr RB]

No it hasn't.

Correct, sorry, an upstream rule chain was still in effect.... NOW it has been resolved, thanks for letting me know.

Now it comes up with a web page, which contains a lot of "should be up shortly".

 

[jimlovell777]

Unfortunately that's accurate. I'm the only maintainer for the site and it's taking me some time to go through everything and get it posted. It's not the only project on my plate so time spent on the site is not what I would prefer. I appreciate people taking an interest, I'm doing what I can.

Maybe I'm being a bit curmudgeonly here, but if "It's not the only project on my plate so time spent on the site is not what I would prefer.", why post the link and take everyone else's time looking up an empty page? It really irritates me when companies put up a home page that has links to "all" of their product or service pages only to find some (many...most) are only labled "Under Construction" or image blocks labled "Coming Soon".

Rant over. Now I'll go get some coffee.

I apologize for wasting anyone's time, that's not something I want to be doing.

Perhaps that line read wrong, I want to be spending more time on the site, not that I see it as a nuisance. In fact I'm working on it as I type this.

Perhaps I put the cart before the horse in this instance but really I didn't want to drag out the site release and wait for everything to fall into place. I'd rather let things slowly roll out and gain standing based on merit. Gaining page rank, users, pageviews, content all takes time, due to my present circumstances time is not something I can afford to waste.

thanks for ur reply, jimlovell 777.... can u tell me what that 'PROPER MANNER' refers to?

I am in the middle of intelligent traffic lights system and I need to be guided or helped about the circuit diagram or how to connect distance measuring sensors

 

[jimlovell777]

Proper manner meaning you're sending data in accordance with the PS/2 spec. When you're trying your project out do you have a second keyboard attached? If so PS/2 or USB? Has the computer booted into the OS before you attempt to send scan codes with your microcontroller?

To get help with your project please start your own thread if you have not already done so.

 

[srikanth.kallakuri]

ya this is the thread started by me. And i have all the possibilities using ps2 ( with a second keyboard, with the second, restarting after connecting the pic circuit, sending the data in the required frequency and with required start stop parity etc....................) but i dont understand why the system is not accepting my code. Can anyone confidently say that the system accepts the information given in the keyboard format from a mc through the ps2 port? im about to stop trying in this direction and start with usb. If anyone know such projs plz reply me.....

 

[jimlovell777]

Yes it can/will work If you've done everything right the computer won't know the diference between a uC and a real keyboad.

 

[srikanth.kallakuri]

is there anything that im overlooking like the response at the time of bios check etc???

 

[jimlovell777]

It's hard to say without knowing more about your project. Do you have a schematic we can look over? Source code? Compiler? etc....

Perhaps this might be of help uC PS/2 Protocol

 

[srikanth.kallakuri]

ya we use a similar link for guidance... neway thanks for ur reply. I will catchg u up tomorrow with the schematic and complete details. right now i dont have those details
