It's likely even Node.js or PHP could be used if you can control GPIO or Parallel port pins. Net is likely your language of choice (specific flavor C#, VB is up to you). No matter what job I do (excluding hard drive replacements) I run the anti-virus because it 'slows' down their computer, as to whether it effects the 3DMark score, I don't know. If using a Linux based OS, Python is likely your language of choice. ago When they say that the computer runs slow, its often because there's viruses. The control program can be written in any language with that supports the manner of output that will control the 'key' matrix inputs of the keyboard controller, and the usb end plug, plugs into the target computer as a usb keyboard as desired.
Craft your control program using the mapping.Map out the pins either by examining the contact matrix, or by.(It goes without saying, that soldering will be required.) Disassemble it and take the controller and usb plug section, then wire-up your 'controller' to the contact connections intended for the keyboard matrix.Buy a cheap usb keyboard, the ones that are like $5 to $20 or so.However, for any others with a similar question, I propose the following solution: Given the time between the OP and now, this may be moot.
