    I have been using I2C between Rpi & PIC16f877 with the PIC running at 3V.

    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

    You can use 3.3V pull up resistors instead of 5v pull up. Otherwise you can refer this also : https://www.adafruit.com/datasheets/an97055.pdf
