    Hi, I have been used 2 resistances of pull-up by 1k as suggested by the tutorial of the microchip.
    I will add "end" at the end of the program.
    thanks

    1K might be a bit strong in a single chip situation. Try 4.7K and 10K also.

    Common issues are not pulling WP lead to Vss (ground), not pulling A0:A2 to ground (but this doesn't apply to 2K chips), crossing clock/data lines and the pull-up resistors. I use 4.7K resistors for less current draw. The code looks clean except for the previously noted lack of END at the end of the program. The second 'Pause 10' (after i2cread) serves no practical purpose, but it won't kill the program.

    Is the hardware proven good, as in Mr. Blinky? Is the serial com working okay?

    Edit: I see Mr. Skimask (I'm assuming something here) said it first while I was typing... what he said.
