interrupts

Tutorial Overview In this tutorial we will add code to a peripheral template generated by the Peripheral Wizard to create a simple timer. The peripheral will generate an interrupt when the timer expires. The Microblaze will process the interrupt through an interrupt handler function which gets called whenever the interrupt occurs. In this example, we will make the LEDs flash by using the interrupt handler function to switch the state of the LEDs and reset the timer. [Read More]

Overview In this tutorial we will improve on the Timer peripheral developed in Create a Simple Timer Peripheral. The improvement is achieved by enabling the peripheral to generate an interrupt when the timer expires. The PowerPC then processes the interrupt through an interrupt handler function which gets called whenever the interrupt occurs. In this example, the interrupt handler function will switch the state of the LEDs and reset the timer. [Read More]
