Hello everyone! Does anyone here have some experience with CC1101? I wanted to know how hard would it be to control its frequency with a microcontroller. I have read that people do it either by writing data to this chip's registers or by modifying capacitors/chokes on the circuit. Which approach is correct? is it even possible to do that? Thanks in advance.

Does anyone here have experience with CC1101? From what I know, it is possible to make a circuit for multiple frequencies with a single chip but I couldn't find any reliable information about it. People either mention writing to internal registers or changing capacitors/chokes. Which solution is correct? I would like to control the frequency with a microcontroller in the similar way that flipper zero does it. Are there any examples I can take advantage of?
