alt_write_word(h2p_lw_led_addr, Mask );

The Mask in this statement decides which bit in the data register of the PIO IP is high or low.  The
bits in data register decide the output state of the pins connected to the LEDs. The program for the
HEX controlling is similar to the LED.

Since the linux operate system support mult-thread software. The software for this system creates
two  threads  one  for  controlling  the  LED  and  the  other  for  controlling  the  HEX.  We  can  use  the
system  call  pthread_create  to  complete  the  job.  The  function  is  called  in  the  main  function  and  a
sub-thread is created. The program running in the sub-thread is to control the led flashing in a loop.
And the main-thread in the main function is to control the digital shown on the HEX changing in a
loop. The LED and HEX’s state changing at the same time when  the FPGA is configured and the
software is running on HPS.
