For using sleep functionality, sleep, msleep, or usleep APIs provide delay in multiples of seconds, milliseconds, and microseconds.

For configuring interval timer functionality, execute the following steps.

  1. Configure the interval period in XTimer_SetInterval API
  2. Register the internal timer handler in XTimer_SetHandler API. This API is executed when the interval time expires.
Note: By default, XilTimer library is disabled in the Vitis classic flow except for the FreeRTOS hello world template app. You can enable it through the library software configuration wizard as needed. However, in Vitis Unified IDE flow, the xiltimer library is enabled by default and all the sleep and ticktimer functionality is acheived through the use of this library.

XilTimer provides the following user configuration BSP settings.
