WebConfiguring and installing the RTOS tick interrupt. Every official FreeRTOS demo that targets an ARM Cortex-A based embedded processor includes code to configure a timer to generate the RTOS tick interrupt, and install the FreeRTOS tick interrupt handler. The following information is only required if you need to change the provided implementation. WebPolled interrupts are handled by using software which is slower than hardware interrupts. Here the processor has the general (common) interrupt service routine (ISR) for all devices. The priority of the devices is determined by the order in which the routine polls each device. The processor checks the starting with the highest priority device.
