1. If you are reading other pins on Port B, which ones are they ?

2. Do you guarantee that there is no ICD2 or ICD or anything similar
plugged into your board ?

what i meant by saying ...

There are two possibilities:

1. It could be some low-level problem with TRIS or a Read-Modify-Write
problem, that affects the hardware i2c port.

2. It could be a design error in your ...

output_low_all();
if (INPUT(S8)==0) slave_buffer
if (!INPUT(S8)) slave_buffer[2]=88;
[/code]

thanks for correcting me, but it works if i read inputs from port A. it hangs only when i use ...

ooops, sorry about that.
here comes the program. This is the shortest i can give you, cause you need to know the i2c routine interrupts and anything shorter than this will not be much useful i guess. ...

1)thanks for the pointer, even some of port A pins take ANALOG inputs.

2)i2c bus is working fine when i use Port A pins as inputs, and it only hangs if i use any of the port B pins as inputs ( ...

Iam attaching what you asked for,

1)
#include <16F87.H>
#fuses HS, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP,NOMCLR
#use delay(clock = 20000000)
#use i2c(slave, sda=PIN_B1, scl=PIN_B4)

2) ...

2. Do you have NOLVP in your #fuses statement ?
If not, then add it.[/quote]
