TMS320F28379D: F28379D & MATLAB-SIMULINK

user6412891

I am using the F28379D board and simulink to generate a 30 kHz sine wave through the DAC, but when I increase the sample time to more than 1E-6 (sample time) to get more samples the delivered signal is no longer correct.

I appreciate any information.

HI,

I re-uploaded the images in a new comment is the scheme I am using and some settings. my problem is that when lowering the sample time to more than 1e-6, I get a signal that does not correspond to the correct one, from 10 kHz I get 141 Hz. I am using matlab version 2020a and code composer 10.1.0.
