Change clock, from external 72MHz to internal 48MHz
Posted: Mon Oct 05, 2020 11:43 am
Hello,
I want to use an STM32F103 without external oscillators. My experiments are on a Bluepill and I am trying to change the clock from external clock 72MHz to internal clock 48MHz. I know which registers i have to change, but i don't think that it is so easy. I can't make it to work.
What is the procedure?
