hello all,

Can anyone please look at this code, according to me it must work, with a
littlebit of adjustments it works fine with the 24c65 eeprom. Right now i
think i work according specs of the i2c, but quiet different of peter
anderson's code.

Any help is appreciated!!

More information on the bus mightprove interesting.

You don't mention if you are using the new high speed bus, but if youare, you may find this of interest:

From the year 2000 I2C Specs -

········"Onthe bit level, a device such as a microcontroller with or
········ withoutlimited hardware for the I 2C-bus, can slow down
········ the busclock by extending each clock LOW period. The
·········speed of any master is thereby adapted to the internal
·········operating rate of this device."

the chip i'm using has 8 registers thati want to read, it seems two
readings work fine, rest looks like garbage. with a different startaddress
that two looks fine, rest looks garbage etcetera

Are you using single master, or multi-master ?

many thanks pieter-jan

Yup
