TM4C123GH6PGE: Usage of system Timer (SysTick) in usb_dev_serial example

Hello,

What is the purpose of the system tick timer in the usb_dev_serial example?

3.1.1 System Timer (SysTick) in the data sheet explains the various uses.

However, I do not know what it is used for in this example.  

regards,

Jame,Shin

    Hi Jame,

      It is not necessary to have the systick in this example. It is left there perhaps as a place holder. I remove all the reference to the SysTick in the code and it still works. You can try it too.
