Hello,
Sys/Bios gives the following error when I try to assign INT13 to an HWI.

I thought INT14 was the only timer assigned to the RTOS. Sys/Bios gives the following error If I assign INT14 to the HWI.

Am I allowed to use Timer 1 for an HWI?
Stephen
By default SYS/BIOS will use one timer for the Clock module and one for the Timestamp module. There are ways to tell them use specific timers (for example, the TimestampProvider.timerId parameter) or to tell them to use the same timer (although at the cost of making Timestamp less efficient).
There's a Timer Managment section on this page that may be helpful:
[FAQ] Are there any C28 device specific items with TI-RTOS (SYS/BIOS)? - C2000 microcontrollers forum...
Other Parts Discussed in Thread: TMS320F28069 , TMS320C28346 , SYSBIOS Can you explain any C28 device specific items within the TI-RTOS kernel?
Note: SYS/BIOS
So to answer your question directly--yes, you can use Timer 1 for a Hwi, but you have to use the methods above to configure Clock and Timestamp not to use it first.
