Is it possible to do serial I2C communication with other than SDA and SCL pins. Can I use PGD and PGC pins ?

I have tested your Proteus project with PIC16F877A and works fine. Then I decided to replace PIC16F877A with […]

Your library handles only single byte of information. ////SLAVE CODE DATA READ // if(!SSPSTATbits.D_nA && !SSPSTATbits.R_nW) { z = SSPBUF;//Address Read while(!BF); d=SSPBUF;      //data Read SSPCONbits.CKP = 1; inputflag=1; }

In PIC I have 20Mhz XTAL and in Atmega also. I think that the problem is in Atmega(Slave), because when i run the program in PIC, the SDA and SCL  works well ( i see this in oscilloscope). […]

I would like to use 5V on all circuits and supplies. Is it possible to use 5V on the I2C pins of RPI? I cannot see that a levelshifter will work, please help. Thx
