I have tried using the example given for the I2C memory, but continue to read either 0 or 255 on the inVal when using debug.  The 0 is with the pull-up resistor removes and the the 255 with it installed.  i have used two different new memory chips with the same result.

I have grounded pins 1,2,3,4 and 7.  pin #5, SDA goes to RA.2 and pin #6, SCL goes to pin RA.3.  Both of the RA lines have a 4.7 K pull-up resistor.

In the step mode, I can see the SDA and SCL pulsing.

I am usign version 3.2

 

Any ideas?
