Cannot configure multi-channel sampling with ADC produced by CUBE. The value of multi-channel sampling and acquisition is incorrect. After the study, it was found that the underlying function did not clear CHANNEL.
Just add hadc.Instance->CHSELR = 0; in the function to clear the register manually.
Encapsulated Transformers are simply transformers in which one or more of the transformer's components are completely sealed. One example of a component is the transformer's coils. This process of encapsulation protects the transformer from dirt, dust, moisture, and any other contaminants.
