When I type sudo i2cdetect -y 1 or 0, I get "... No such file or directory"
I have read several articles and posts.
I have enabled i2c in raspi-config
When I type lsmod | grep i2c, 2c_dev and i2c_bcm2708 show.
I have uninstalled and reinstalled python-smbus and i2c-tools.
I have tried it with the device tree on and off.
config.txt contains
dtparam=i2c_arm=on
dtparam=i2c1=on
dtparam=spi=off
device_tree=
There is no blacklist file
uname -a shows ...raspberrypi2B 3.18.10
My older Pi works fine. I have noted the in the /dev/ folder on the older Pi, there are files i2c-0 and i2c-1. These files are not in the /dev/ folder for the B+
Since this is new, I'm not sure a fresh format and reload would help. A hammer may make me feel better for a short time. Any other suggestions?
