From: Martin Griffith on 5 May 2008 15:49 I'm working on my pension scheme project. 99% worked out, coded and I just need one little extra. I need to embed text info into my serial datastream ( that is going through my 8051) from the usual PC/mac coming from the keyboard in an open text document, Word, Open Office etc. Probably use FTDI stuff on my 8051 board. That is echo the keyboard to a USB/ serial port, one way only. I don't have a clue of where/who/how to look for it thanks martin

I have to admit that I can't make much sense out of this post and I can see a number of different ways to parse it. Are you asking about a software application for the PC or an embedded device that monitors the keyboard signals? If the latter one of the hardware key logger designs should prove a good place to start. There is an 8051 based design at http://www.usbkeylogger.org/diy.html that you might find useful. -- Andrew Smallshaw andrews(a)sdf.lonestar.org

I'm asking for a bit of PC/mac sw that will send the PC/mac keyboard to my 8051 box of tricks, as well as it's intended application. I will get somebody else to write the user manual :) martin

If you want a hardware wedge, that's fairly challenging for USB, BUT once you've got it working it will continue to work regardless of OS and even across software updates and antivirus scans. A software keyboard wedge is going to require constant maintenance since it is pretty much by definition malware. For Windows it's fairly simple <http://www.codeguru.com/vb/gen/ vb_system/keyboard/article.php/c4829/>. For MacOS it's a bit harder. |
