GPIO to ADC channel mapping in STM32F105RBT.

Hello,

I'm currently working on an application using STM32F105 uC.

I want to use some GPIO as analog input, so I need to use the ADC converter.

It seems that each channel is linked to one ADC channel. I have found some table with this mapping for other devices, but unfortunately I cannot find this table for this specific device.

(I attach STM32F3 a equivalence table just for your reference.)

With best regards,

Didac

They're in the pinout information in the datasheet. "ADC12_IN12" is shorthand for "ADC1_IN12 and ADC2_IN12".
