    T3.5/6 I2c pin re-assignment query

    On T3.5/6, is it possible to re-direct SCL1,2 or 3 to Pin 35 and the corresponding SDA1,2 or 3 to Pin 30.

    Reason being that I'm building a piece of hardware on a Mega protoshield intended to work on either an Arduino DUE or a Talldog DUE breakout. The DUE has a second I2c port on Talldog's pins 35 and 30.

    Thanks in advance for any insights.

    No, not unless you solder wires. The muxes inside the chip for those pins simply do not have any I2C signals connected.

    Thank you Paul. More pins and header shunts to be added so end-user can configure accordingly.

    All the best.
