Hi everybody,I think I found a bug in stm32l4xx_hal_exti.h at the definition of the GPIO-ports:#define EXTI_GPIOA 0x00000000u#define EXTI_GPIOB 0x00000001u#define EXTI_GPIOC 0x00000002u#define EXTI_GPIOD 0x00000003u#define EXTI_GPIOE 0x00000004u#defi...

Posted on July 09, 2018 at 18:19Hi everyone,going through the datasheets of STM32L4x1 processors (probably concerns further processors as well) I found that LSE is always limited to 1MHz but my question is what limits it, i.e. can I use LSE > 1MHz i...
