Defines a driver to facilitate interfacing with the GPIO pins.
Use this driver to control the behavior of any desired pin, such as driving a 1 or a 0, or as part of other drivers such as controlling the chip-select (CS) line for the SPI driver.
| void wiced_hal_gpio_register_pin_for_interrupt |
( |
uint16_t |
pin, |
|
|
void(*)(void *, uint8_t) |
userfn, |
|
|
void * |
userdata |
|
) |
| |
Register a function for notification of changes to a pin (via interrupt).
- Parameters
-
| [in] | pin | The pin number from the schematic. Range [0-39] Ex: P<pin> |
| [in] | userfn | Pointer to the function to call when the interrupt is triggered Below is the description of the arguments received by the call back. void* user_data - User data provided when interrupt is being registered using wiced_hal_gpio_register_pin_for_interrupt(...) uint8_t value - Number of the pin causing the interrupt |
| [in] | userdata | Pointer that will be passed back to userfn as-is. Typically NULL. |
- Returns
- none
- Note
- This function is independent of configuring the pin for interrupts; a call to wiced_hal_gpio_configure_pin() is also required.
-
Also note that once registered, you CANNOT unregister; registration is meant to be a startup activity. To stop receiving notifications, re-configure the pin and disable the interrupt using wiced_hal_gpio_configure_pin()
-
(!) Note that the function does not need to clear the interrupt status; this will be done automatically.
-
(!) Note that the function will be called ONCE per interrupt, not once per pin (this makes a difference if multiple pins toggle at the same time).
Example:
void gpio_int_test_cb(void *data);
wiced_hal_gpio_configurePin(WICED_P01, (GPIO_INPUT_ENABLE|GPIO_PULL_DOWN|GPIO_EN_INT_RISING_EDGE), GPIO_PIN_OUTPUT_LOW);
wiced_hal_gpio_register_pin_for_interrupt(WICED_P01, gpio_int_test_cb, NULL);
