Good day! Sorry for my English, I’m from Belarus…
My problem is that I killed the i2c gpio pin on my raspberry pi and now in order to connect the display I need to enable the additional i2c bus. I try to do this by adding the line dtoverlay = i2c-gpio, bus = 3, i2c_gpio_delay_us = 1, i2c_gpio_sda = 17, i2c_gpio_scl = 27 to the /boot/config.txt file. After that the raspberry pi do not start. I tried downloading the official raspbian jessie and then i2c remapping works! The problem is in the Volumio 2 distribution. Please help me!
