Looking for a simple PS/2 keyboard test program for the PicoMite VGA. I’m testing a number of keyboards for a friend, and the good ones will be donated to Goodwill. Looking for a graphical layout of a standard 101 key keyboard onscreen. I press each key and if the key press registers, the key turns green onscreen. The PicoMite seems a good fit, as it boots in 2 seconds. An old Windows PC takes at least a minute, and you can’t hot swap a PS/2 keyboard. Has anyone written such a program they would like to share? |

You can make this very fancy, but many people will have to look at the keyboard, and then the screen, an then the keyboard, and… But humans can look and listen simultaneous…. Do A$=Inkey$ If A$<>"" Then 'Print Asc(A$) Select Case Asc(A$) Case < 32 Play tone 400,400,100 Case > 90 Play tone 500,500,100 Case Else Play tone 600,600,100 End Select EndIf Loop You can test all keys except num_lock and caps_lock. But these have LED's on a typical keyboard. The tone is different when you press <CTRL-H> or <SHIFT-H> or <H>, that is how you check the control and shift keys. Be carefull about caps_lock when it's ON you cannot detect shift key is operated. Success Volhout Take care with <CTRL>+"C".... Edited 2024-04-12 18:10 by Volhout PicomiteVGA PETSCII ROBOTS |
