How can i modify ADC for multiple channel interrupt?

Sukumar21 — Sun, 08 Oct 2023 07:22:08 GMT

I am using s32k146 EV board, there is an sample code given RTM 4.0.3 adc_hwtrigger_s32k146.

I tried this code for ADC. IT works perfectly. But using same code how can i read ADC for multiple channels.

I want to modify the same code for 8 channel ADC, with ADC channel been used are SE06/07/08/09 and SE12/13/14/15 for ADC0.

This is an swTrigger example, this is good. but i am looking utilise interrupt either adc or pdb. so is there sample code with adc interrupt or using PDB

Hi@Sukumar21

You can take a look at this routine, but with DMA added
