Hi,
I am trying to read a 1 cell lithium ion battery voltage with ADC channel 2 at IO3 on esp32s3
the batt+ is connected to a voltage divider two 10k resistors then connected to IO3 pin.

Re: How to modify IRAM size
Hi @ronnie.zyd
I am facing a similar problem but at earlier stage.
I don't know what to change to be able to modify the DRAM Segments and get more RAM in the static allocation segment.
but you seemed to manage to do so.
Can you offer some help?
How did you know what files and what values to change?
