mmmmh. Hat das was zu bedeuten ?:

Ds1631 = 158
Ds1631r = 159

&H90 is eigentlch 144 dezimal oder spinn ich jetzt

die ds1631 ist die schreibadresse
ds1631r leseadresse wenn a0,a1,a2 nicht auf GND liegen

Hallo Leute

Vielen dank für eure hilfe ich habs geschafft

Nun der Code der auch funktioniert:

      $regfile = "m16def.dat"
$framesize = 60
$swstack = 60
$hwstack = 60
$crystal = 8000000
$baud = 4800

Config Scl = Portc.0
Config Sda = Portc.1
