Hi all,

Working C code for PIC16F87x (100Khz for XTAL 10Mhz).
Configure:
InitI2C();

Read RTC:
aux_buff[0]=1;
GetI2C(0xD0, 1, 2, aux_buff);
seconds=0;
minutes=BcdToDecimal(aux_buff[0]&0x7f);
hours=BcdToDecimal(aux_buff[1]&0x3f);

Write RTC:
aux_buff[0]=1;
aux_buff[1]=DecimalToBcd(minutes);
aux_buff[2]=DecimalToBcd(hours);
SendI2C(0xD0,3,aux_buff);

NOTE:
RC3 and RC4 should be Outputs.

Hope Helps,

NeuralC
