Interrupt problems

[Erimads]

I ned a function  with 2 interrupts on input pins one on rising edge and one on falling edge.

This is the code.

CY_ISR(PulsOn_interrupt) // Frankfurt Ur interrupt Puls on
{
PulsOn_ClearPending();
PauLen=PulCnt;
PulCnt=0;
PausOk=1;
Blue[18][1]= 0x80;
Blue[19][1]= 0x80;
}

Started with this order.

 PulsOn_StartEx(PulsOn_interrupt);
 The problem is the interrupt is running all the time,

No code outside this interrupt is executed.

I have 2 other interrupts on internal clocks one for timing and one for scanning a LED matrix running allright.

The input pin is set up to no HWconnection, Transparent and Rising edge interrupt.

The interrupt are set up to DERIVED.

I can add som info.

The problem is only with Rising and both edge not with falling edge.

I have tryed pull up and pull up and notthing is connected to the input pin at this test.

Regards Erik.

I have tryed a delay before starting interrupt.

Erik,

Are you willing to share your project with this thread?  This will help to diagnose your issue.

[Erimads]

Yes.

I am making an alarm clock

To this I are using the following.

1. A board from Sparcfun FreeSoc2 with processor CY8C5888AXI-LP096

2. A 16x32 RGB LED matrix to show Time, weekday and date and other info

3. A keypad with 6 buttons to setting time/alarm time

4. Then I need to connect a receiver to get timecode signals from the timecode sender in Frankfurt Germany at 77.5 khz. It is hear I need the HW interrupts.

What files du you need to see the complet project ?

Regards

Erik

Hi @Erimads ,

I understand that you need interrupts on both the rising edge and falling edge in a digital input pin.
You may configure this. In the configuration window -> Pins tab -> Input tab -> Interrupt. You may select "both edges". You may also select "dedicated interrupt" depending on the device that you are using.

I have now find a solution, I have changed the input connection.

Se the cut from TopDesign.cysch showing what works and not works
