Enumeration Type Documentation

Current an output pin can drive in active and sleep modes.

Definition at line 35 of file gpio_arch.h.

void gpio_pm_sleep_enter ( unsigned mode )

Called before the power management enters a light or deep sleep mode.

Parameters

mode	sleep mode that is entered

void gpio_pm_sleep_exit ( uint32_t cause )

Called after the power management left light sleep mode.

Parameters

cause wake-up cause

int gpio_set_drive_capability	(	gpio_t	pin,
		gpio_drive_strength_t	drive
	)

Set the drive-strength of an output-capable pin.

Sets the drive-strength for an output-capable pin in active and sleep modes. The default drive-strength is GPIO_DRIVE_20 (20 mA).

Parameters

pin	GPIO pin
drive	drive-strength GPIO_DRIVE_5 for 5 mA GPIO_DRIVE_10 for 10 mA GPIO_DRIVE_20 for 20 mA (default) GPIO_DRIVE_30 for 30 mA
