The timer_hw_oneshot example is the equivalent of timer_sw_oneshot implemented with the on-chip timer. In this example, one task is created to process the interrupt and it waits for a notification to unblock and execute. The expiration of the hardware timer triggers an interrupt and the ISR sends a notification to the interrupt processing task. This is done to defer the interrupt processing to a task and minimize time in the hardware ISR that is not part of the RTOS kernel scheduling. After the notification is received, the task is unblocked and prints the current tick count on the terminal window.
