(Reporter) How do I stop waiting for n seconds before renewal? (SOC) (de2) (nio ii)

Abstract
Since the CPU speed is too fast, many people cannot see the result at all. Therefore, how can we find C in the case of niosii if we want to stop running for n seconds and then try again?

Introduction
Environment: US us II 7.2 SP3 + niosii eds 7.2 SP3 + de2 (Cyclone II ep2c35f627c6)
This example uses(Formerly known) de2_nios_lite 1.1 (SOC) (nano II) (Systems builder) (μC/OS-II) (de2)For example

The usleep () function is provided in unistd. H. You can stop running n micro-seconds. To stop running for n seconds, it is equivalent to usleep (N * 1000*1000 );
