    System freezing problem caused by an interrupt

    taehoon.jeong

      Hi all, attached zip file is my working project.

      As you can see in this file, I'm using two push buttons of CY8CKIT-050 PSoC 5LP Development Kit(P6_1, P15_5) to change the strings of LCD module.

      The interrupt associated with the button P15_5 works fine(CY_ISR(subSel)), but when I push the button P6_1(CY_ISR(mainSel)), the system freezes.

      I cannot understand the reason of this phenomenon because these two switches basically do the same thing.

      Thank you in advance.
