TMS320F28379D: ePWM frequency

Siomi Shiniji

Part Number: TMS320F28379D
Other Parts Discussed in Thread: BOOSTXL-DRV8305EVM

Hello Community,

  1. Why when I use the DAC modul all signal's frequencies are devided by 2? Shall I do any special configuration to have the same frequency in Simulink and the scope?

  2. I'm trying to generate ePWM signals using the divice TMS320F28379D to control the BoostXL-DRV8305EVM. I made my program using Matlab/Simulink as shown in the figure.

When I configure the ePWM frequency I obtain the quarter of what I want. It mentioned in the help of Matlab that "For a few TI C2000 processors, there may be a PWM clock divider that divides the SYSCLKOUT to derive the PWM module clock."

My question is How to set this clock if I want receive the same frequancy (configured_Frequency=obtained_Frequency)?

Regards.
