After more tries, i found out that only the pin A0 and the pin A2 are working. I think i can't use the other one as analog input, like we can see on that picture : So, the other pins are useless ?

So, the other pins are useless ?

Yes, these Arduino pins are not connected to MCU pins...

See User Manual, it seems that you can connect A1 pins to PA_0 with SB7, A3 to PA_4 with SB8, A4 to PB_9 with SB11 or PH_0 with SB, and A5 to PB_8 with SB12 or PH_1 with SB10

Ok, thanks for all !
