Re: Interrupt problem (beginner) Hi Paja,


Then just modify the drive mode of the input pin in the project to Resistive Pull Down.

Tha should get the project working.

All the best !

Re: Interrupt problem (beginner)  Hi dasq.

Thank you very much for help. The kit I use have a push button connected to +Vcc (I can see it in a data sheet).

I will try your project today.

Thanks once again.

Re: Interrupt problem (beginner) I created a project similar to the one you have stated and tested it on PSoC5 using CY8CKIT-001.

The output LED toggled upon every switch press (SW1).


The working project is attached for your reference.

Re: Interrupt problem (beginner) Hi Paja,


Which kit are you using to test this project?

If you are using CY8CKIT-001 or CY8CKIT-050, then the switch available on board (SW1 and SW2) are push-to-ground.

Hence, configure the input pin's Drive Mode as Resistive Pull Up.



If you are using CY8CKIT-014, the switch is configured as push-to-Vcc. Hence, the drive mode for the pin should be set as Resistive Pull down.

If configured this way, the pins will not be floating.

Secondly, the header file of the pin you are intending to toggle should be included in the isr. Use the macro

#include "Pin_2.h" in the isr_1.c file

Re: Interrupt problem (beginner) Thanx for a fast reply.

I'll definitely try it.

Re: Interrupt problem (beginner) There is a function named ISR_Clearpending(). Have a look at the API and try, this may hewlp you.


Happy interrupts
