for the porta.4 you must put a resistor 10k to the Vcc 5v but for the rest maybe it is license problem  |

when you use the eeprom do not miss delay >=5ms after writing in the eeprom

Hi all
There is a little trick to simulate the I2C devices on proteus. When you put the pull-up resistors. Click on left button on Edit properties, select Digital instead of Analog. Click on OK button. That's it.
I hope this be useful for everybody.
Elreypic.

hi
change pull-up resistor from Analog to digital not solve the problem for me
values read from eeprom 24c32 change but not the real values that I program on it
thanks for your opinion.
