Hi community ,
we are using IMX RT 1020 for our next design and we just want to know if there is any provision to read all the 16 inputs i.e (DC1_IN0 to ADC1_IN15 ) with a single trigger .
Here are the available ADC selection , in 24 proposed ADCs we can use only 19 , 16 from ADC 1 and 3 from ADC 2
If there is any provision to read all the 16 sensors data connected to 16 ADCs of the MCU in one shot please let me know since reading individual input is a time taking process and includes latency
Thanks and Regards

Hi Naren chandra,
No, you can't use single trigger to get all the 16 channel ADC data.
In fact, even each ADC module contains 16 channel, to one ADC module, the max configuration adc channel is 8, please check the following register information:
You can find just one ADC_HS register, so to one time, it just can check one channel conversion completion.
But you can configure 8 channels one time. If you use two ADC modules, you can use up to 16 channels.
But, you still need to use the code to process the individual ADC channel value.
Wish it helps you!
if you still have questions about it, please kindly let me know.
Have a great day,
Kerry
