Hello @leonggz,
The ADC conversion triggered by the PWM via PDB is possible in MBDT via the configuration blocks of all the mentioned peripherals. I have attached below the main settings, highlighted in the configuration blocks, just as the trigger signal occurs in this chain. First, the initialization trigger for the FTM needs to be enabled. In the PDB block, the trigger of the configured FTM Timer instanced needs to be selected, like below, the FTM3 Initialize Trigger. Finally, here, in the ADC_Config block, the control needs to be grated to the PDB peripheral.
We do provide an example, called ftm_pdb_adc_chaining_s32k14x.mdl and it is delivered with the toolbox. Here, the FTM3 initialization trigger is used for both PDB0 and PDB1, to trigger each PDB instance a channel of the ADC0 and ADC1 respectively, basically converting two ADCs at the same time. The results are read via the PDB ISR, where the ADC block is used to read the values.
Another way of reading the conversion results for the ADC is performed via the ADC interrupt and this method is used inside the Motor Control examples, also delivered with the toolboxes.
What we don't have no in the MBDT blocks is the configuration block for reading data via DMA. If you are interested in particular to read data via DMA we can add the missing part via the Custom code.
Please let me know if you have further questions!
Regards,
Marius
