Hello,

I have bought STM3220G-EVAL board (model number MB786) and I am not sure

which ADC module is used for potentiometer RV1 voltage sampling. I have found

that the potentiometer is connected to PF9 pin and I have found in the datasheet

CD00237391 on page 48 that PF9 pin is probably connected to ADC3 module

channel 7. Can anybody confirm to me that it is right? Thank you in advance.

    Hi

    steven

    ,

    Yes you are right ,A potentiometer RV1 is connected to ADC3of STM32F207IGH6 (PF9 ).

    Please refer to BSP example under the STM32F2 firmware package:

    STM32Cube_FW_F2_V1.4.0\Projects\STM322xG_EVAL\Examples\BSP: This example provides a description of how to use the different BSP drivers.
