Hello @ALİ ÇALIŞKAN​ ,

The LL_ADC_SetChannelPreSelection function set the pre-selection of channel configuration.

• Caution: Channel selections is dependent to ADC instance and IP version: For STM32H72x/3x this is applicable only for ADC1/ADC2. For rest of STM32H7xxx this is applicable only all the ADCs instances.

Please have a look at the UM2217 "Description of STM32H7 HAL and low-layer drivers", which detailed description of each peripheral driver: configuration structures and functions.
