Hello community ,
I am Naren , I recently was searching for a MCU that suits our application and came across this crossover processor , MCU . I.MX RT 1020
As per the data sheet it says there are two ADC channels with 16 inputs (2 * 16 = 32 inputs ) , but when i go through the reference manual and pinout , i observed that there are multiple ADC inputs assigned to the same MCU pad , because of which it makes only 19 inputs available at a time for use , check the excel of pinmux comment if i am wrong and suggest me a solution , since i need at least 30 ADC inputs but only 19 inputs i can use .
If you look at the image here , for example PAD GPIO_AD_B1_15 has ADC1_IN15 and ADC2_IN15 to select from and here i am losing one ADC channel .
Please share a thought on this .
Hi , Thanks for the response ,
I have made the excel sheet from the same table you have sent found in the reference manual .
Check the same , there are multiple ADCs allocated to the same pad and so do we are losing the ADC channels
GPIO_AD_B0_15 has both ADC1_IN2 and ADC2_IN2 allocated and we can use only one which is losing one channel from describing of 32 channels in the data sheet to 19 channels in reality
check this below image
