I wrote an Assembly code to read and write EEPROM (24LC32) from PIC16F877 using I2C protocol. It works when reading or writing is done alone. But when I combine the codes and try to write and read it stops after writing. If anyone has a code for I2C please help me. [/code]

Re: I2C

hi
I faced the same problem before. It was due to bus collosion that was happeneing
Try to poll on the SSPIF after each step in the protocol and it will work

Code: 
BTFSS	PIR1,SSPIF
GOTO	$-1

Kindly try and tell me

thanks
