Is it possible and how to use other GPIOs than ADC_INxx as analog inputs ?

[YRAGO]

The Reference Manual of the STM32L1 talks about "Up to 40 external I/OS can be used far data acquisition purpose in conjonction with the ADC interface".

The ADC_INxx pins number is smaller...

I saw that we can root pins with the "Routing Interface" peripheral.

NO

You can put the pins in to an analogue mode, in this context it will turn off the schmitt trigger on the digital side of the input.

They are not available in every 'L1 model, and not in every 'L1 package.

I looked into STM32L151xD datasheet and counted 43 ADC_IN pins (although they repeat so can't be used simultaneously).
