ADC_LDD and PDB component working together ?

[mkrug]

Hello,

I figured out that you can not directly use a FTM block to trigger an ADC. It has to be done by a PDB (or PIT, RTC which I have not tried yet).

Did someone has successful implement the ADC_LDD and PDB_Init component to work together. All the examples that are distributed uses ADC_Init and PDB_Init to get them work together. However, then your are loosing all the Methods that make live easier to work with the ADC.

Best Regards

Hello,

in FTM there are additional bits that enables the trigger output. See EXTTRIG register for details. However from your issue is not clear if you are using Init_FTM or TimerUnit_LDD with FTM device selected to trigger the ADC.

In case of Init_FTM, there should be no issue if you enable appropriate bits.

In case of TimerUnit_LDD the EXTTRIG register must be additionalt initialiazed in the user code - this is known issue, it should be resolved within CW V10.3.

Regarding ADC_LDD and Init_PDB example, I will try to search some example if exists, otherwise we will try to prepare it for you.

I also would like to understand how to make the ADC_LDD component work with Init_PDB. I cannot seem to get the ADC to trigger using PDB.

Has this been fixed in the latest PEx?
