Calling a function periodically

Nithin Ramesan

Hi.

I'm trying to write a program that will call a function to read data from memory periodically, i.e, every 1 ms. How might this be accomplished?

Thanks.

Hi,
You may have to write ISR routine to call that function for every 1ms.
What is your processor ?

I'm working on a C66x EVM. I'm trying to write the program for the CorePac DSP.

Could you direct me to the necessary documentation necessary to implement an interrupt service routine?

Hi Nithin,

Please refer below wiki for interrupt configuration in keystone,

Please refer the examples available in MCSDK and below threads for usage,

Thank you.

Hi. Thank you for your reply. I am however using the 6614 EVM, and as such, do not have access to the 6678 PDK mentioned in the links you shared. Is it possible for you to share the timer example here on the forum?

Hi Nithin,

Attached the timer example here.

Please find the MCSDK 2.x download and user guide link below my signature.

Thank you.

Thank you. Just to confirm, the timer can be configured to call a function periodically as well, right? Not only for a one-time call?

It depends on how you configure the timer.
