I am running CentOS. I added the line : dtparam=i2c_arm=on to the end on the config.txt then reboot. After reboot I ran the test program and still get the error: Unable to open I2C device: No file or directory. You have mentioned manual load the I2C-dev. can you give more details. I am running CentOS.
Does anyone know how to enable I2C for CentOS to use with the WiringPi library on the Paspberry Pi?
I am trying to run the I2CSetup Interface but having the error "Unable to open I2C device: No such file or directory".
