I2C comunication between 1 16f877 master and 2 16f873 slaves

[moacir_mendes]

I had a lot of problems during implementation of this circuit, more specifically with i2c protocol.
To get and send bytes between the master and one slave it works perfectly. But when i tried comunicate with other slave PIC no one more comunicate.
To solve this problem i do a test with SSPOV and BF bits, what indicates overflow on the buffer.
If one of that are high i make it low.

I had a lot of problems during implementation of this circuit,......

Most if not all the problems with I2C master/slave of PIC16 have been fixed with 7.5 SP3.
HOWEVER - as Dave states - you'll need to prove to us you've been using a legal copy of Proteus or you won't receive any support from us ! It shouldn't that hard to understand ?
