Many thanks for this reply!! So for the Master I can use a PIC18F452. (Thanks to the link what you gave me). But for Slaves it would be better to use already ...

Hello Javi, That's a nice and interesting project what you got there. It doen't look very easy indeed. But for only a Master (18F452) it shouldn't be to hard...
Hi Atmoz, The library have 2 sections, one that manages "raw data" through master I2C and the second one that uses previous procedures to implement EEPROM read...
... First try to answer what your goal is. Do you need to transmit information over distance? I2C is not a good solution in this case. For several reasons. Do...
