I2C Slave with a PIC

[Wirecut]

Thanks to all of you for your greath wok!

... just to avoid to have trouble in future and have a clear view of a new project, I have in plan to use the slave routine on almost 12 PIC of 18F2550 and one Master with 18F4550.

The idea is that:
I shall have the Master far from the first slaves at about two to three meters and the second slave is far from the first slave around 50 cm, and all other slaves are distanced 50 cm between them.

At the end the total length shall be more than 10 meters. but less that 12 meters.

Also, I would use the RJ45 connectors to make interconnection between the PCBs and use the preassembled CAT5 Ethernet patch cable to carry the supply voltage from the Master to the slaves.

I have thinked to put on pin 1, 2 and 3 the VCC, on pin 4 the Clk, on pin 5 the Dat and on pin 6. 7 and 8 the GND?

The lenght of the cables can be a problem?

The idea to use the RJ45 with the CAT5 patch cable is good?
