I am trying to go over the TI-RTOS labs.

I am trying to follow this note from lab 1:

Clock_tickPeriod

To use Clock_tickPeriod, remember to include the kernel Clock module header: #include <ti/sysbios/knl/Clock.h>

The value of this variable [µs/tick] is determined when the TI-RTOS .cfg file is parsed. If Clock.tickPeriod = nn; is not present in the .cfg file, the default value is used. Since the tick period can vary between projects, it's useful to include the variable Clock_tickPeriod in calculations that depend on system clock ticks.

What do I need to do to look up the Clock.tickPeriod?

Clicking on the .cfg file in this lab or in any other project is not showing anything.

Thanks,

Priya

When I click on the .cfg file in this lab or in any other project, I am not finding anything.

Where do you want to look this up?
In your c code, you can directly reference Clock_tickPeriod.
On the CC2600, the default Clock.tickPeriod is 1000 (1000us per tick) but this is generally changed to 10 (10us) for an increased clock tick resolution.

I'm using the CC2650 DK. I assumed I'd be able to open some file in the lab1 project or some where in the workspace to find this default value. The tutorial mentions a .cfg file. Can I just assume this value defaults to 10 us?
Thanks,
Priya
