TMS320F280049: PWM register is not changing

rakhyung lim

Part Number: TMS320F280049

Hi,

I tried to modify PWM register, however that doesn't work.

tried bit-wise and word-wise, but any changing on registers

the register is not protected. eventhough do "EALLO", same result.

any one who can give me a hint?

thank you.

Can you try refreshing the registers window to see if the values were updated and just not shown?

is the epwm clock enabled ?

Hi, Nima.

thank you for quick feedback.

I tried refreshed register window and still same.

the most frustrating thing is that GPIO register could be edited, however, GPIO couldn't.

I even tried forcing register as *(int*)0x4000 = 0xD04A; to modify PWM TBCTL register.

wow..

right that was peripheral clock issue.

how do you know that information. I could find on the technical datasheet.

thank you so much!!!!!
