Hi,
I'm dealing with a AT89C51ED2. I'd like to use the kbd-interrupt, which rises when input on P1.x changes.
But when code is compiled the following error come up:
Error 13: UNKNOWN INTERRUPT [KBD]
Is there a way to solve that problem or isn't this interrupt supported by BASCOM?
Thank you for your help. Smile

Code:

$regfile "89C51ED2.dat"
$baud = 9600                                                  'set your own baudrate
$crystal = 20000000

Dim S1 As String * 16
Dim I As Integer
Dim Count As Integer

On Kbd Kbd_init

Enable Interrupts
Enable Kbd                                                    'set your own crystal frequen

 Do
   Print Count
   If Count > 10 Then
      I = Makeint(p1 , P4)
      S1 = Bin(i)
      Print "Port1: " ; S1
      Count = 0
   End if
 Loop
End

Kbd_init:
Incr Count
Return

you can add them to the dat file.
open it with notepad then make sure the end of the file looks like this :

[MISC]
I_TIMER2 = 2B
I_PCA=33
I_KBD=3B
I_DUM=43
I_SPI=4B
up=89C51ED2
IRAM = 256
org = 2E
clockdiv = 6


to enable the interrupt you manual need to set the register : Ie1.1 = 1
