LAUNCHXL-F28379D: How to update commands for CPU timer? F28379D

Sneha Thakur77

Part Number: LAUNCHXL-F28379D

I have the same issue as discussed in this thread:

https://e2e.ti.com/support/microcontrollers/c2000/f/c2000-microcontrollers-forum/880736/ccs-launchxl-f28379d-how-to-update-commands-for-cpu-timer

I have changed the configcpu timer to ConfigCpuTimer(&CpuTimer0, 200, 5); from ConfigCpuTimer(&CpuTimer1, 200, 1000000);

I want to sample at 200 kHz. I have not changed CpuTimer0Regs.TCR.all = 0x4000;

Now, after some time the PWMs freezes, even though the CpuTimerCount keeps incrementing.

As discussed in the above thread, I am not able to find the solution of what needs to update in CpuTimer0Regs.TCR.all .

Can anyone please help?

Thanks

Hi Sneha,

If you disable the timer do you still see an issue with your PWM output?

The TCR register is the control register for the CPU-Timer. The technical reference manual has the information about the different bits within the register and could help guide you on what needs to be updated. If you only changed the period value then you can leave it as is: CpuTimer0Regs.TCR.all = 0x4000.

Best Regards,

HI Marlyn

Thank you for the reply.

The issue has been resolved. I had used the timer counter at wrong place.

Thanks
