But they certainly have a counterpart in the ADC library of f0xx.
That's all I can think of.:smiling_face_with_smiling_eyes:

I made a correction in the code let's try deleting the unit16_t part in while
Uint 16 in loop should be Uint 32 or Uint should not be written.

Thank you. I have now only this error. Because i use STM320XX.h i change the code.
ADC_ChannelConfig(ADC1, ADC_Channel_9, ADC_SampleTime_55_5Cycles);
ADC_StartOfConversion(ADC1);
that doesn't work yet :(

ADC_RegularChannelConfig(ADC1, ADC_Channel_9, ADC_SampleTime_55_5Cycles);
should be

Unfortunately, no. Does not work yet
