Hi there,
The allocation process is allocating some pins as "X".
This means that, automatically, were allocated MCU pins not wired to C4MINI connectors (which causes your issue) but also every needed peripheral's configuration. Take each configuration detail as a reference.
The golden rule to make a system work is that "all the pins displayed on the connection matrix MUST be connected". So your GPIOS and NTCs have to be allocated manually to some available MCU pin.
To do that you should take a look to the AEK_MCU_C4MINI extended connector, which can be also found on the C4MINI User Manual.
The pins you want to allocate are ADCSAR, so you should search in the scheme above which MCU pin are allocable as ADC.
When you find it:
In red you can see which P"x"y" combination configurable as ADC (i.e. PG5)
Then open
In the top left of the screen search for the pins you are looking for:
our C4MINI should have every pin allocated already, so you should see it highlighted in green.
If you click the pin, you will find it highlighted on the ADCSAR Outline window:
NOW, left click on the pin previously displayed with the "X" and copy the name from the General setting window:
Then right click on the PIN and deallocate it, selecting NOT USED:
Now deallocate the PG5 (if already allocated) and allocate it once again, as:
Make sure to paste the name you copied before!
Remember the name of the peripheral (ADCSAR12b_S) and the Channel number.
Now by clicking on lowleveldrivers from the project explorer, select SARADC Settings, and check if the corresponding SARADC is enabled:
then create a new SARADC Configuration (if you are creating from scratch) or use the one generated, making sure to have the following configuration:
And the correct channel selected:
Repeat the procedure also for other ADCs, then Save all, clean and compile.
Your application should no more have "X" pins allocated and the correct ADC configurations.
