s32k144 pwm dead time setting

[alice_th]

i have a quesiton, if want to generate waveform like this,

i see there have dead time enable, can the dead time can set longer time, is there have parameter  set ?

another questions, it seems only Adjacent channel(n and n+1) can set the dead time,

does ch0 and ch7 or some other random channel  combination with dead time set ?

third question is can different FTM channel generate same waveform 

with dead time, like FTM0 ch0-ch1 waveform ?

[alice_th]

could you help answer the three question i list , thanks, here is my test project

Hi,

Thank you so much for your interest in our products and for using our community.

In S32 Design Studio for S32 Platform v.3.5 and RTD for S32K1 and S32M24x version 2.0.0 the parameter to set the Dead Time ticks is in the following tab:

On the other hand, the deadtime insertion is only available for each complementary pair, since its purpose is to ensures that no two complementary signals (channels (n) and (n+1)) drive the active state at the same time.

I share with you an attached sample code for the above mentioned software installation.

Hope it helps you.

Have a nice day!

where can download the RTD package ?

i am using 3.5, there is no deadtime paramter setting

i also compile your project share, there lots of error, maybe miss some packages ?

[alice_th]

thank you very much for the information, can different FTMx chx generate these waveform ?

Hi again,

Seems that you are using another RTD, demo works with this setup:

On the other hand, maybe you do not need dead time insertion, for your waveform drawn on paper you need Phase Shift, please refer to the following post:

https://community.nxp.com/t5/S32-SDK/phase-shifted-pwm-channels-in-s32k144/td-p/1894512

Hope it helps you!

[alice_th]

with my tool i can't find the package which you show, only autosar have

[alice_th]

@_Leo_ 

also i search in web, i didn't find the package you mention
