In my new project I want to use 20 ADC channels. From the document I understood the adc sequencer can support upto a maximum of 8 channels.  so I can use only 16 channels with both ADCs.  How to use all 20 channels.

Regards,

Ramesh

    You have two ADC converters each with four sequencers. If your goal is to sample each of the 20 channels periodically, use both ADCs and use two sequences on each. You can have each ADC do 8 channels on sequence zero then two more on sequence 1. Program all four sequences to trigger off of a timer and set the two sequences to different priority levels.

    Hi Bob,

    Thanks for the suggestion.  I was thinking only one sequencer is allowed per ADC  So I understand now multiple sequence can be programmed per adc. Will trigger all four sequences periodically.
