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,

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.
