Hi, has someone tried implmenting I2C in AT89C51? Did it work? If yes, can you give me some tips in order to get a succesful communication,please?
Thanks for your help
I said "think" because it is what I read or understand for ttl levels. The datasheet said that the ports are ttl , so 3V I think is enough.
Did it?
There will be a section where it specifically defines the threshold voltage levels for logic "High" and "Low". That's the bit you need to read!
