Nikolaj,

when dinosaurs roamed the earth the 8051 had no HW I²C and was a very popular I²C 'driver' (it still is, but now many derivatives have HW I²C). Thus, you can find plenty of working code (albeit for a different processor) at places such as 8052.com ANYHOW DO NOT CONTINUE untill you have scoped your SCL, I am VERY suspicious of your 'delay' and the use thereof Erik
