Read all assigned keys from Keyboard

[WoodGrain]

Hi All,

I've bought a Ergodox EZ programmable keyboard with layers of key maps (eg, layer 0 = dvorak, layer 1 = numberpad & nav, layer 2 = qwerty, etc), I've also got a small USB screen that can pull information from the registry. What I would like to determine is a way to pull the value of each current key from the keyboard, I can then write the values to the registry and pull them into my USB screen so I can see the keyboard key layout.

I'm stuck with retrieving the key values, I've looked at _IsPressed(), _WinAPI_GetKeyState(), _WinAPI_GetKeyboardState(), _WinAPI_GetKeyboardType(), _WinAPI_GetKeyNameText(), but none of them appear to be able to pull the keyboard key values without user interaction.

The idea being, in pseudo code, bear in mind no error checking etc in this code, "GetKeyValue()" is what I'm needing help with and is a made up function, as is "HardwareKey1" etc:

$keyOnePrev = ""
$numOfKeys = 76
While 1
   $keyOneCurrent = GetKeyValue(HardwareKey1)
   If $keyOneCurrent <> $keyOnePrev Then
      For $key = 1 To $numOfKeys
         $keyToWrite = GetKeyValue(HardwareKey & $key)
         RegWrite("HKEY_CURRENT_USER\Software\myKeyboard", "key" & $key, "REG_SZ", $keyToWrite)
      Next
   EndIf
   $keyOnePrev = $keyOneCurrent
   Sleep(5000)
WEnd

Thanks guys!

typos, update $keyOneCurrent script location

I'm guessing this is not possible?

what is wrong with the built in registry functions? also, while you are at it, pseudo code the GetValue function too.
