Function Documentation

changeInterruptTrigger() [1/2]

void changeInterruptTrigger ( miosix::GpioPin gpio, InterruptTrigger trigger )

inline

Changes interrupt trigger on an enabled interrupt.

Parameters

gpio	Pin (eg: PC4)
trigger	Interrupt detection trigger (rising edge, falling or both)

Definition at line 97 of file external_interrupts.h.

changeInterruptTrigger() [2/2]

void changeInterruptTrigger	(	unsigned int	gpioPort,
		unsigned int	gpioNum,
		InterruptTrigger	trigger )

Changes interrupt trigger on an enabled interrupt.

Parameters

gpioPort	Port of the pin (eg: GPIOC_BASE)
gpioNum	Pin number (eg: 4 for PC4)
trigger	Interrupt detection trigger (rising edge, falling or both)

Definition at line 411 of file external_interrupts.cpp.

disableExternalInterrupt() [1/2]

void disableExternalInterrupt ( miosix::GpioPin gpio )

inline
