How to improve the ADC precision?

[zhujt4github]

The default precision of stm32G0 is 12 bits. How can I increase the precision to 13 bits or higher?

Hi,
simply use analogreadresolution():

Anyway G0 max ADC resolution is 12 bits so increasing the resolution will simply map the resolution which will not be very precise.

Thanks for your reply,
In the stm32g0 manual I found this below:

A native 12-bit analog-to-digital converter is embedded into STM32G030x6/x8 devices. It
can be extended to 16-bit resolution through hardware oversampling.

Do we have this feature or similar features? If not how can I achieve this feature.

No oversampling is not managed.
If you want achieve this then you will have to use HAL to configure and use ADC with the oversampling.

Got it, thank you very much!
