I have a ready-made project for STM32F103T8u for an 8MHz oscillator, but I had to replace the oscillator with 16MHz. It would seem nothing difficult to change HSE from 1 to 2 and get the required parameters at the output, but I noticed that now my second lasts half a second and I have no idea what can be checked.
Maybe I phrased it wrong. Despite the fact that I changed the divider and all frequencies should have changed, this did not happen, UART(i set 115200) works at frequencies 115200x2, HAL_delay (1000) lasts 500ms and so on.
