emmmm,i just had a question,i wanna use multiple rti interrupts,but id not know the scope of each individual rti.

I am very sorry that I did not find the tag about rti.

Thank you to every engineer who saw my post. Thank you!

Hello,
Your question is more device specific than tools specific. Hence I will move this thread to the device forum

Thanks

Hello,
RTI module can generate 4 time based interrupts that comes from compare unit and two from free running counters. Free running counters generate interrupts when counter overflows.
Each of the compare registers can be configured to be compared to either counter 1 or counter 2. When the counter value matches compare vaule, an interrupt is generated.
You can find more information on RTI module in device TRM ( www.ti.com/.../spnu515c.pdf ) Section 13.

HALCoGen can be used to configure RTI module.

Best regards,
MIro

I'm sorry I didn't fully describe my problem, but I used the setperiod function in the main function to set the interrupt frequency between compare0 and compare3, and then called various compare.The current problem is, I don't know where to write operations that correspond to different frequencies.

Hi,
If I understand right you don't know where to write ISR. Am I right?
