How to use an external barometer with navio2

Navio / Edge Hardware
2

@Guiboy Hi! There are two ways to do this:

  1. Hardware way:
    a: Unsolder MS5611 chip from the Navio board.
    b: Connect external MS5611 with address set to 0x77 (using address selection pins of the chip) to the I2C port on Navio.

  2. Software way:
    a. Change Ardupilot code by setting MS5611 address for Navio to 0x76 and compile it.
    b. Connect external MS5611 with address set to 0x76 (using address selection pins of the chip) to the I2C port on Navio.
