C++ (Cpp) enable_gpio_irq Examples

Example #1

File: windspeed.c Project: i7sid/SkyNet-Dongle

/*
 * you want to use this!
 */
int calcwindspeed(){

	int curtick = 0;
	int speed = 0;
	disable_gpio_irq(2,13);


	curtick = cnttick;
	cnttick = 0;
	float div = Chip_TIMER_ReadCount(LPC_TIMER2)/ticksPerSecond;

	Chip_TIMER_Reset(LPC_TIMER2);
	enable_gpio_irq(2,13);
	DBG("div:%f count:%d\n",div,curtick);

	speed =  curtick*(2.25/(div))*1.609344*100; //mph to km/h to 100m/h
	return speed;
}

Example #2

static unsigned int startup_gpio_irq(unsigned int irq)
{
	enable_gpio_irq(irq);
	return 0;
}

Example #3

static void end_gpio_irq(unsigned int irq)
{
	if (!(irq_desc[irq].status & (IRQ_DISABLED|IRQ_INPROGRESS))) {
		enable_gpio_irq(irq);
	}
}
