Hello,

I'm trying to detect rising edge with one handler and falling edge with another handler. Is it possible with the BL4S200 API?

With the code next, only the photocell_up_isr() is called on falling edge!

// Rising handler
root void photocell_up_isr()
{
photocell_up_count++;

// Turn off all interrupt flags serviced by this handler
RSB_CLEAR_ALL_IRQ(photocell_up_handle);
}

// Falling handler
root void photocell_down_isr()
{
photocell_down_count++;

// Turn off all interrupt flags serviced by this handler
RSB_CLEAR_ALL_IRQ(photocell_down_handle);
}

void photocell_init()
{
int result;

photocell_up_count = 0;
photocell_down_count = 0;

photocell_up_handle = addISR(PHOTOCELL_1, BL_INPUT_BLOCK, 0, photocell_up_isr);
photocell_down_handle = addISR(PHOTOCELL_1, BL_INPUT_BLOCK, 0, photocell_down_isr);

result = setExtInterrupt(PHOTOCELL_1, BL_IRQ_RISE, photocell_up_handle);
result = setExtInterrupt(PHOTOCELL_1, BL_IRQ_FALL, photocell_down_handle);

result = enableISR(photocell_up_handle, 1);
result = enableISR(photocell_down_handle, 1);
}
Thank you for your comment.
