- Mon Feb 08, 2016 6:22 pm #40740 When using I2C using the Wire library I can use the default pins for SDA/SCL (from the good old Arduino it was A4, A5) or choose my own pins.
Many libraries use the Wire library themselves but do not let me choose the pins.

Is there any generic method to add pin suport for any library? (it it usually not very comlicated to clone the library's init method an add support for pins, but it is not convienient...)

just init the i2c in your sketch as you need. This should override and set the defaults for the library.
