please friends help a beginner with i2chello people I'm in big trouble i2c, I'm using

[nomad]

also need to add "TRISB = 0" somewhere before using lcdout. (default is input, need to set to output)
Also, make sure Low voltage programming is disabled, it uses portb.4.

HELLO personal thanks for replying,
I pulled the ADCON1 and put the CMCON = 7 and appeared error symbol

Nor did the case of states i2c address you explain to me or write code to perform this address
because the lcd was already running and the data were recorded in eeprom 24c32a
the difficult that even this reading is made of the data in the EEPROM and show lcd

thanks for helping me

sorry, i'm lost as how to help. your code should not compile at all.
(I tried in microcode studio, fixed all the errors, and posted the result.)
Are you sure you've selected 16f628a? it has comparators and uses cmcon.
I've used them before and checked against my old projects and the data sheet.
what I posted compiles fine here with no errors. (Although I did not correct the i2cread section to get the full string for display)

If nothing at all is displaying, there's bigger issues.

make sure 16f628a is the chip youre using, and it is selected in your program!
