STM32C0 - use internal oscillators

[STbeginner]

Hi all,

i have selected the MCU STM32C051G8GU6 as the main controller of the RFID system and i am trying to use the MCU without using any external crystals or oscillators, can anyone please guide me how to use the internal oscillators.

Thanks in advance

Easiest way would be to just get CubeMX to configure it for you.

Even if you don't end up using the generated code in your final project, it will show you everything that needs to be done.

 

Otherwise, you will have to study the Reference Manual - that will have all the details of clock configuration, etc.
