RTOS/TDA3: How to disable interruption and task switching in processor SDK vision

Part Number: TDA3

Tool/software: TI-RTOS

Hi,

In Processor SDK Vision 3.00, what is the best way to prohibit interrupts and task switches for a certain period of time on DSP or EVE?

I want to use variables shared by multiple tasks in the same processor. When one task is rewriting the shared variables, I want to disable task switch and interrupt so that the other task or interrupt handler does not rewrite it . Could you let me know how to make it prohibit on the SDK?

Hi Kenshow,

You can explore the usage of Hwi_disable() and Hwi_restore for this functionality. This will block interrupts in the critical section of your code.

Thanks and Regards,

Hi Piyali,

You mean that I can use SYSBIOS function on the SDK framework like usecase.
For example, can I use task_disable() for disabling task switch?

Hi Kenshow,

"You mean that I can use SYSBIOS function on the SDK framework like usecase."

Yes.. You can use SYSBIOS functions in the SDK framework and Usecase.

"For example, can I use task_disable() for disabling task switch?"

Yes... You would need to include the appropriate header files of the modules you want to use Task, HWI, SWI etc.

Thanks and Regards,
