ti.sysbios.family.c28.Timer.Instance#0 : Invalid Timer RunMode: 2?

Steve,

This error is thrown because the dynamic reprogramming timer mode (RunMode_DYNAMIC) is not supported on C28 devices. 

If you want to have variable periods at runtime I think the only way to do this is to dynamically create one shot timers (RunMode_ONESHOT) at runtime, specifying the next period for expiration.

Scott,

    Thanks for the quick answer. A follow up question then is why, if the BIOS timers map to hardware timers and the hardware timers can be configured dynamically, is there the limitation imposed by BIOS? Seems like it would be easy for the Timer_setPeriodMicroSecs just to go change the value stored in the register.

Steve,

Sorry for the confusion!  I was too focused on telling you that RunMode_DYNAMIC was not available on C28. :OP

As an alternative to dynamic one-shots, yes, you can indeed create a periodic timer (RunMode_CONTINUOUS), and then change the period dynamically, as described in the cdoc description:

 key = Hwi_disable();    
 Timer_setPeriodMicroSecs(period);      
 Timer_start();
 Hwi_restore(key);
