Function Documentation

aducm3029_irq_ctrl_init()

int aducm3029_irq_ctrl_init	(	struct no_os_irq_ctrl_desc **	desc,
		const struct no_os_irq_init_param *	param )

Initialized the controller for the ADuCM3029 external interrupts.

Parameters

desc	- Pointer where the configured instance is stored
param	- Configuration information for the instance

Returns

0 in case of success, -1 otherwise.

aducm3029_irq_ctrl_remove()

int aducm3029_irq_ctrl_remove

(

struct no_os_irq_ctrl_desc *

desc

)

Free the resources allocated by no_os_irq_ctrl_init()

Parameters

desc	- Interrupt controller descriptor.

Returns

0 in case of success, -1 otherwise.

aducm3029_irq_disable()

int aducm3029_irq_disable	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id )

Disable the interrupt.

Parameters

desc	- Interrupt controller descriptor.
irq_id	- Id of the interrupt

Returns

0 in case of success, -1 otherwise.

aducm3029_irq_enable()

int aducm3029_irq_enable	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id )

Enable the interrupt.

In order for the irq_id interrupt to be triggered the GPIO associated pin must be set as input.
The associated values are:

• ID 0 -> GPIO15
• ID 1 -> GPIO16
• ID 2 -> GPIO13
• ID 3 -> GPIO33

Parameters

desc	- Interrupt controller descriptor.
irq_id	- Id of the interrupt

Returns

0 in case of success, -1 otherwise.

aducm3029_irq_global_disable()

int aducm3029_irq_global_disable

(

struct no_os_irq_ctrl_desc *

desc

)

Disable all external interrupts.

Parameters

desc	- Interrupt controller descriptor.

Returns

0

aducm3029_irq_global_enable()

int aducm3029_irq_global_enable

(

struct no_os_irq_ctrl_desc *

desc

)

Enable all previously enabled interrupts by no_os_irq_enable().

Parameters

desc	- Interrupt controller descriptor.

Returns

0

aducm3029_irq_register_callback()

int aducm3029_irq_register_callback	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id,
		struct no_os_callback_desc *	callback_desc )

Registers a IRQ callback function to irq controller.

Parameters

desc	- The IRQ controller descriptor.
irq_id	- Interrupt identifier.
callback_desc	- Descriptor of the callback. If it is NULL, the callback will be unregistered

Returns

0 in case of success, -1 otherwise.

aducm3029_irq_unregister_callback()

int aducm3029_irq_unregister_callback	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id,
		struct no_os_callback_desc *	cb )

Unregister IRQ handling function for the specified irq_id.

Parameters

desc	- Interrupt controller descriptor.
irq_id	- Id of the interrupt
cb	- Callback descriptor.

Returns

0 in case of success, -1 otherwise.

irq_action_cmp()

int32_t irq_action_cmp	(	void *	data1,
		void *	data2 )

Action comparator function.

irq_action compare function

Parameters

data1	- List element
data2	- Key

Returns

0 if the two are equal, any other integer otherwise
