EXT_CHANNEL_23 in S32K146

[bjrajendra]

Hi,

I'm trying to use S32K146 module & standard SDK_GCC in order to use ADC module.

As the S32K_RM suggests S32K146 -144LQFP supports ADC with 24 channels which can be selected using ADCSCR register.

 But in the adc module which I selected from the library is not showing EXT_CHANNEL _23 instead it shows only till EXT_CHANNEL_15.

Also I observed that it takes CPU with 100 pin but I couln't able to see how can I modify to 144 pin

Kindly help in this regard.

Hi,

if you have active 100pin package in your project the ADC component cannot allow you select channels above 15.

So you need to switch to 144pin package, see steps given here
