how to configure ADC3 multi channel using interrupt method in NUCLEO-H745

[ggowd.1]

Hello Team,

I am unable to configure ADC multiple channels in NUCLEO-H745ZI if I configure multiple channel ADC, voltage at channel 1is same as channel 2 but I have supplied channel 1 voltage as 3.3v and channel 2 voltage as 1.6v but it is reflecting 3.3v in both channels. How do I overcome this?

Use DMA to convert multiple ADC channels.

Hello TDK,

Using ADC in DMA I need configure external timmer trigger but unable to get output in that. So that without DMA i am configuring external timmer trigger i am getting output in that so I need to use multi channel ADC. Is there any configuration in ADC_DMA as external timmer trigger??
