Hi Sir:

Is it possible to use DPWM1,DPWM2, DPWM3, DPWM4 to sampling trigger EADC1/CLA1 consecutively?

How to set DPWM to realize this? do you have any example source code?

thanks a lot

You can't do that on the 3028 or any UCD30xx family member. If you want to do fancy things with sample trigger, you have to go to the UCD31xx family with the loop mux. Then you can do all kinds of things with the sample trigger.

In the 30xx family, each DPWM and EADC are tied together. Notice that the control registers for each pair of DPWM/EADC are even in the same address space. That tells it all.
