I'd like to set a gpio to be an output then toggle it using the GPIO Interfaces module built into linux.
ie.:
gpio_direction_output(unsigned gpio, int value);
gpio_set_value(unsigned gpio, int value);
My problem is what to use for the value unsigned gpio - this is a number that gets mapped to a pin on the processor.
Once I get this mapping then I can refer back to the schematics and choose a pin that is connected to one of the connectors.
I can't find this mapping in the documentation and I am not experienced enough to figure it out from the source code. Although if someone pointed me in the right direction I could probably find it :-)
