ADC1 channels numbers

Hi community,

I have a custom board with iMX RT 1062 XVN5B, i want to measure 15 ADC channels separate in 2 groups :

Group 1 : 8 channels ADC1.1 to ADC1.8, trigged by CH0_XBAR_TRIG, 0 » PIT_TRIGGER0 (100 uSec)

Group 2 : 7 channels ADC1.9 to ADC1.15, trigged by CH0_XBAR_TRIG, 1 » ADC_ETC_XBAR0_COCO0

I use the config tools like this :

ADC1 : 15 channels

When i read the ADC_ETC_TRIG _0 results « ADC_ETC_GetADCConversionValue(ADC_ETC, ADC_ETC_TC_0, 0 to 7) » corresponding to (ADC channel 1 to i get correct values.

When i read the ADC_ETC_TRIG _1 results « ADC_ETC_GetADCConversionValue(ADC_ETC, ADC_ETC_TC_1, 0 to 7) » corresponding to (ADC channel 9 to 15) i get nothing.

I am looking for a solution to read the 16 channels of ADC1
