I2c-3 Port on balenaFin


#1

Good evening,

just for curiosity, is i2c-3 provided by the FTDI / FT2232H chip on BalenaFin - or where does this additional port comes from?

Thank you very much,

Nico

Hello Nico,

The I2C-3 is provided by bit-banging on two GPIO pins (42->SCL, 43->SDA). The FTDI chip is used to interface with the Artik020 module.

Cheers,
Nicolas
