Function Documentation
| void gpio_irq_disable | ( | gpio_irq_t * | obj ) |
Disable GPIO IRQ.
This is target dependent, as it might disable the entire port or just a pin
- Parameters:
-
obj The GPIO object
| void gpio_irq_enable | ( | gpio_irq_t * | obj ) |
Enable GPIO IRQ.
This is target dependent, as it might enable the entire port or just a pin
- Parameters:
-
obj The GPIO object
| void gpio_irq_free | ( | gpio_irq_t * | obj ) |
Release the GPIO IRQ PIN.
- Parameters:
-
obj The gpio object
| int gpio_irq_init | ( | gpio_irq_t * | obj, |
| PinName | pin, | ||
| gpio_irq_handler | handler, | ||
| uint32_t | id | ||
| ) |
Initialize the GPIO IRQ pin.
- Parameters:
-
obj The GPIO object to initialize pin The GPIO pin name handler The handler to be attached to GPIO IRQ id The object ID (id != 0, 0 is reserved)
- Returns:
- -1 if pin is NC, 0 otherwise
| void gpio_irq_set | ( | gpio_irq_t * | obj, |
| gpio_irq_event | event, | ||
| uint32_t | enable | ||
| ) |
Enable/disable pin IRQ event.
- Parameters:
-
obj The GPIO object event The GPIO IRQ event enable The enable flag
