I want to get an Arduino shield working on the Olimexino STM32, but the shield makes critical use of I2C on analogue ports A4 and A5 (D19 and D20 on the Olimexino). If I set D19 and D20 to Input Floating, could I short these two pins (and thereby the I2C signals on the shield) to I2C2 on D29 and D30? Would the D19 and D20 pins interfere with the I2C in any way? Could I disable pins D19 and D20 completely?
Thanks

Hello Bhante,
I cannot recommend anything that has to do with hardware modifications as this will void your warranty.
The safest route here is to buy a bunch of jumper wires and connect each pin to whatever you like.
