Probier mal folgendes:
Code:
'test.BAS: Rote LED an Pin PD3, gelbe an Pin PD4, grüne an PD5
'--------------------------------------------------------------
$regfile = "m8def.dat"                                      'ATMega8
$crystal = 16000000                                         'Quarz: 16 MHz
config portd.3 = output                         'Pin PD3 als Ausgang konfigurieren
config portd.4 = output
config portd.5 = output

Do
set portd.3
wait 1
set portd.4
wait 1
reset portd.3
reset protd.4
set portd.5
wait 1
reset portd.5
set portd.4
wait 1
reset portd.4

Loop
End
