MOD-ZIGBEE-PIR interrupt

vlcak · March 28, 2016, 10:47:40 AM

Help my, please.

Testing MOD-ZIGBEE-PIR and still generate interrupt , someone advise me where I am wrong?

Environment : board MOD-ZIGBEE-PIR, programer PIC-KIT3, MPLAB X IDE v. 3.20, compiler XC8

Below it is a simple example to test interruption PIR and buttons. Interrupt buttons is OK, but comparators PIR sensor reports constantly interrupted.

Thanks!
