Hello everyone,
I use the f28379D TI target on the MATLAB 2018a version. I need to use a Timer as independant time base to post interrupts under precise conditions. I see that ther is EV Timer blocks on the c281x librairie:
But about the f28379 I can not find anything that corresponds. Should I use a PWM module and set it?
Also, how to obtain the instaneous value of the timer in order to take action and post interrupts?

Please refer the example 'c281x_asyncscheduling_ert' in which the EV timer blocks are used. And the equivalent model for F2837x 'c2807x_2837xx_asyncscheduling_ert' in which the Timer functionality is realized using ePWM blocks.

Hi Venkatesh, Many thanks for your response. But I would like to reset my Timer on an external evenement. How can I do that using the PWM block parameters?
Thanks.

The Trip Zone unit in ePWM can be used to drive the output high/low based on the external event.
