TIDA-00951: some of the PWM signals are not work

michael coletti

Part Number: TIDA-00951

Hi,

i am checking the firmware before i will modified it for my used , and i am menuall trigger the DSP circuit by apply to the adc's the right voltage.

when i am in the boost mode i dont see that the HV_PWM1/2 are triggerd at all even that i can see that one of them get the new compare value.

and why is the other HV_PWM is commented?

i am not sure if i need to see HV PWM, but im asumme that i am, can you please clear it for me?

Thank you

Michael

Hi, Michael

I see you have get two PWM , so what do you mean by "not triggered "?

the CMPB seems not been used here, it is an action trigger for the same PWM, not another new PWM module.

Hi,

thank you for your answer,

the photo was taken at Boost Mode.

Only the LV PWM's are trigger - at the photo you can see them LV_PWM_PH1 and LV_PWM_PH2 while HV_PWM_PH1 and HV_PWM_PH2 are flat.

At boost mode HV_PWM_PH1 and HV_PWM_PH2 need to be active?

because they are not. and i am not sure if its ok.

again, thank you for your support

Best Regards

Michael

Hi, Michael

I didn't do this code, and can not help too much with coding.

You may modify the code with your understanding. Thanks.
