BF512 软中断使用

1.方法1：

#include


EX_INTERRUPT_HANDLER(IVG14_ISR)
{
    static volatile u32 count;
    count++;
    if (count % 100 == 0)
        AIO_printf("\r\n>>EX_INTERRUPT_HANDLER %d", count);
}

static void SFInterrupt_Init(void)
{
    ex_handler_fn result;

    result = register_handler(ik_ivg14, IVG14_ISR);
    if (EX_INT_IGNORE == result)
    {
        AIO_printf("\r\n>>EX_INT_IGNORE");
    }
    else if (EX_INT_DEFAULT == result)
    {
        AIO_printf("\r\n>>EX_INT_DEFAULT");
    }
    else
    {
        AIO_printf("\r\n>>Addr = 0X%X OK",result);
    }
}

static void SFInterrupt_Raise(void)
{
    raise(SIGIVG14);
}

2.方法2：

#include

static void UserInterruptFunc(int val)
{
    static volatile u32 count;
    count++;
    if (count % 100 == 0)
        AIO_printf("\r\n>>UserInterruptFunc %d", count);
}

#define SIG_NAME      SIGIVG14//SIGUSR2 
static void SFInterrupt_Init(void)
{
    unsigned short imask = *pIMASK;
    imask |= (1 << 14);
    *pIMASK = imask;
    interrupt (SIG_NAME, UserInterruptFunc);
}

static void SFInterrupt_Raise(void)
{
    raise(SIG_NAME);
}
