Detailed Description

GPIO implementation for the BeagleBoard

Definition at line 499 of file main_beagle.cc.

Member Function Documentation

volatile unsigned int* BeagleGpio::getGpioForPin ( int  pin, int *  bit  )

inlineprivate

Gets the correct GPIO MMIO range for a given GPIO pin. The base indicates which bit represents this pin in registers, where relevant

Definition at line 651 of file main_beagle.cc.

void BeagleGpio::initspecific ( int  n, volatile unsigned int *  gpio  )

inlineprivate

Initialises a specific GPIO to a given set of defaults.

Todo:

When implementing within Pedigree, we'll have a much nicer interface for string manipulation and writing stuff to the UART.
