BASICSTAMP send key press ENTER(keyboard)

Can·BASICSTAMP send a command key press ENTER (keyboard) to a computer. ? Like barcode reader that can send ENTER key press if detect barcode.

Thanks

You can send any ascii value from a Stamp to a PC using the SEROUT command.

Not directly, it requires an application on the PC to accept the data and use it as keystrokes.· StampPlot Pro has that ability - see the help files:
http://www.selmaware.com/stampPlot_v3/ext_apps.htm
From the BASIC Stamp you can start an application and then send data to it

[color=black]DEBUG "!APPE c:\program files\microsoft office\office\excel.exe",CR[/color]
[color=#000000]PAUSE 5000[/color]
[color=#000000]FOR X = 0 to 500[/color]
[color=black]  DEBUG "!APPS(RTIME){TAB}", DEC x,"{ENTER}",CR[/color]
[color=#000000]  Pause 100[/color]
[color=#000000]Next[/color]

At times I used·it 'cheat' with some on-line games that had very repetative key strokes - hold a button on my BS2 board and have it send the·key·sequence [noparse]:)[/noparse]

Maybe I'm mistaken, but you need that data to go to a specific application that would normally want keyboard input?· That's what my response was focused on.

Thanks for replay

But i not get answer until now.

In my project i want that BASICSTAMP have detect sensor and basicstamp send key pressed to PC(computer) to do something.This key pressed has function to do something Like Ctrl+O(keyboard) on internet explorer to open File and so on or like barcode reader that detect barcode.

It sounds like you want the Stamp to take the place of a keyboard. I don't recall anyone posting an example of this, but I could be wrong.
Here's an article on the PS/2 protocol and the connections required (in general): www.computer-engineering.org/ps2protocol/.
The Stamp is capable of generating the synchronous data stream using the SHIFTOUT statement. You'll need some external circuitry to provide
for the open-collector connection and you'll need to write your own "driver" to handle the communication between the PC and the Stamp, but it should be doable.

In the past a customer has proven that, while the BASIC Stamp cannot receive PS/2 or AT keyboard data it can send them. I don't know if this will help in our application or not.
