STM32ARM processor experience sharing [Copy link]

When using the STM32F407 processor for precise timing, you can choose the SystemTick clock (the processor has its own system clock), or you can use the TIM6 or TIM7 clock.

The TIM6 or TIM7 clock should be a basic timer. A precise delay still needs a tick timer.

Choose SystemTick clock, advanced timer, general timer, basic timer. Are they all OK?

It just has an internal timer, which is not so accurate.

Whether it is a crystal oscillator or any other clock, there will be errors
