How to identify GPIO Chip and pin

[simonm...@gmail.com]

Hi,
I am trying to use GPIO with the robot control library.
But I cant find the value to pass to chip and pin

ex : 

int	rc_gpio_init (int chip, int pin, int handle_flags)

Thanks for your help

I've used Derek Molloy's excellent GPIO tables for reference. Regarding your question column "Mode 7" would seem to indicate chip and pin numbers, e.g. gpio1[6] would be chip 1, pin 6.
