Hi all! I do not understand. My code {.......... /*Initialize PORT B*/ hard.PortB = gpioOpen (BSP_DEVICE_NAME_GPIO_B, NULL); periphMemWrite(0,PORTB_BASE+PORT_DDR); periphMemWrite(0,PORTB_BASE+PORT_PER); periphMemWrite(255,PORTB_BASE+PORT_IENR); periphMemWrite(255,PORTB_BASE+PORT_IPOLR); archInstallISR(&(pArchInterrupts -> MpioB), PortBISR); periphMemWrite(0,PORTB_BASE+PORT_IAR); /***********************/ .................................................. } Why do not work interrupt?
