The keyword is in SherpaDoug's reply _optimise_. It takes slightly more space, and time, to call a routine that is actually 'separate', than the same code 'embedded' as an 'inline block inside an exis ... |

Hi,
I was out of ROM when I added those two instructions to my program:
printf("\n\r Buffer full");
buffer[5]=0;

thank you again Mr Ttelmah,
it seems that I have some work to do.
The I2C declaration for a 'slave', cannot have a clock speed associated with it.
should I remove "FAST" then ?

Seriously, your problem is not with the I2C.
If the RS232 was working, it'd create a potential problem by spending too long in the RS232 handler (since the hardware buffer is only two characters long ... |

Are you using the I2C interrupt?.
If so, then the problem is almost certainly, that you are spending _too long_ in the handler for this. Look at the example I2C handler, and search here. The key with ... |

If the MCLR pullup doesn't work, there may be a bad connection between your PIC and the LCD. The LCD driver routine features a wait - there's a while (pin low) or something like that which will cause ... |

Put a 10K pull-up on the MCLR pin. (Or use 47K if you're using the
CCS ICD-U40).
The MCLR pull-up resistor is important. Put it in all your designs with the 16F877A.
thank you PCM for you ... |
