run without sudo

[ajal-fh]

Is there anyway to run the app without sudo? I would like to use this library to write a ros package and I need to run the code without sudo. I already tried adding "pi" to usergroup "i2c" and "gpio" but doesn't help

Based on the information I have collected, it seems quite impossible to achieve that with the current implementation.

However, this library for GPIO access looks promising. But, it requires to refactor the leptonSDK lib from current repo.
