In the section DS1307 RTC on the Wiki, the following is not working for me:
sudo echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
The error message is:
-bash: /sys/class/i2c-adapter/i2c-1/new_device: Permission denied
The file is listed as: –w
1 root root 4096 May 7 15:42 new_device
What am I missing?
