Detailed Description

Hardware GPIO data types.

Enumeration Type Documentation

GPIO direction (i.e. function) type.

Enumerator
GOS_GPIO_INPUT_PULL_UP	Input with an internal pull-up resistor - use with devices that actively drive the signal low - e.g. button connected to ground.
GOS_GPIO_INPUT_PULL_DOWN	Input with an internal pull-down resistor - use with devices that actively drive the signal high - e.g. button connected to a power rail.
GOS_GPIO_INPUT_HIGH_IMPEDANCE	Input - must always be driven, either actively or by an external pullup resistor.
GOS_GPIO_OUTPUT_PUSH_PULL	Output actively driven high and actively driven low - must not be connected to other active outputs - e.g. LED output.
GOS_GPIO_OUTPUT_OPEN_DRAIN_NO_PULL	Output actively driven low but is high-impedance when set high - can be connected to other open-drain/open-collector outputs. Needs an external pull-up resistor.
GOS_GPIO_OUTPUT_OPEN_DRAIN_PULL_UP	Output actively driven low and is pulled high with an internal resistor when set high - can be connected to other open-drain/open-collector outputs.
GOS_GPIO_CONFIG_NONE	None. GPIO is unregistered.

GPIO external interrupt trigger edge.

Enumerator
GOS_GPIO_TRIGGER_RISING_EDGE	Interrupt triggered at input signal's rising edge.
GOS_GPIO_TRIGGER_FALLING_EDGE	Interrupt triggered at input signal's falling edge.
GOS_GPIO_TRIGGER_BOTH_EDGES	Interrupt triggered on both edges.

enum gos_gpio_t

Gecko OS GPIO ID

Enumerator

GOS_GPIO_0

This is just a placeholder, this is platform dependent.

GOS_GPIO_MAX

Maximum number of GPIOs the platform supports in Gecko OS.

Maximum number of I2Cs the platform supports in Gecko OS.
