CCS/TMS570LS3137: how to generate high resolution PWM signal?

Hello guys

I want to generate two pwm signals with 10 kHz + 50 Hz and 10 kHz - 50 Hz. but I don't know what I should do.

to increase the resolution I should decrease the "Loop Time", but when I set it to the very small values, it doesn't work anymore. could you please tell me what I should do?

thanks a lot.

Hello Hamid,

Simple PWM signals can be configured in Halcogen. Can you upload your Halcogen HCG and dil project files so we can take a look at how you have ti setup? If you don't use Halcogen, can you upload your HET configuration and program code so we can have a look?

Thanks Chuck for your attention and your quick response.

generating a pwm signal is very easy but its resolution is too low for my application. I don't know hot to set "Loop Time" correctly. how should I know the instructions count of NHET?

these are my HALCoGen configurations:
