I would like to generate 10 signals with a period of around 50us.

I looked in the GTM module on the TC277 and was able to do so, but only with different duty cycles.

But it is required to set for some signals also a different frequency e.g. half.

It is crucial that all of these signals are also exactly edge aligned.

A next step is to send out some SPI commands on one edge of those signals.

I was thinking to use here some DMA features, but I’m not so familiar with that.

Do you think this is possible with the Aurix? And can you give me an example maybe?

Here also a drawing how some signals should look like.

Thanks for your help!

Hi @FMCW ,

Hi
Thank you for your interest in Infineon Semiconductor products and for the opportunity to serve you.
Yes, the GTM is able to generate the above PWMs and you can refer to the application note.
BR,
Jeremy
