TMS570LC4357-EP: Example code for configure 1 ms timer using the RTI

Vasu patel

Part Number: TMS570LC4357-EP
Other Parts Discussed in Thread: HALCOGEN, TMS570LC4357

Hello,

I am currently working with the TMS570LC4357-EP MCU and using HALCoGen to configure the peripherals.

I would like to generate a periodic interrupt every 1 ms using the RTI (Real-Time Interrupt) module. I see the RTI configuration options in HALCoGen, but I am not fully clear on the correct steps to configure the counter, compare value, and interrupt to achieve a 1 ms periodic timer.

Could you please help clarify:

What is the recommended configuration in HALCoGen to generate a 1 ms periodic interrupt using RTI?
How should the compare value be calculated based on the RTI clock?
Is there any example code or reference project available that demonstrates configuring RTI for a 1 ms interrupt on the TMS570LC4357?

Hi Vasu,

E2E has some issue, i am unable to upload any images to guide you easily.

You can find one example in below path of HALCoGen:

Help -> Help_Topics -> Examples -> example_rtiBlinky.c

If you open above example there you can see step by step guidance to configure RTI for 1sec interrupt.

You can refer this example and configure your required time period instead of 1sec.

Similarly, you can also refer below e2e:

[FAQ] TMS570LC4357: Examples and Demos for Hercules Controllers (E.g. TMS570x, RM57x and RM46x etc) - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

In above e2e you can find section called "LED Blinky / RTI:" there you can find some attached examples based on RTI, you can directly download and import those into CCS and can do the testing directly.
