Hi! I have an STM32L0 nucleo board and I want to calibrate HSI using LSE; I have read the application note: AN4631 that explain a solution: at page 12 is possible to see the Hardware connection with TIM21 CH1 in capture/compare configuration;
But... I don't knew how to translate this info into CUBE-MX configurator for a correct result
Could you please tell me how to set it? please help me, thank you very very much.
