| * | |
| * This is the common API for GPIO. Additional features are available | |
| * in the documentation of the specific modules. | |
| * | |
| * \section io_group_platform Platform Dependencies | |
| * | |
| * The following functions are available on all platforms, but there may | |
| * be variations in the function signature (i.e. parameters) and | |
| * behaviour. These functions are typically called by platform-specific | |
| * parts of drivers, and applications that aren't intended to be | |
| * portable: | |
| * - gpio_pin_is_low() | |
| * - gpio_pin_is_high() | |
| * - gpio_set_pin_high() | |
| * - gpio_set_pin_group_high() | |
| * - gpio_set_pin_low() | |
| * - gpio_set_pin_group_low() | |
| * - gpio_toggle_pin() | |
| * - gpio_toggle_pin_group() | |
| * - gpio_configure_pin() | |
| * - gpio_configure_group() | |
