Changing the system clock source is a fastidious task because of AHB, APB1 and APB2 limits, -//! which are chip-dependent. This example assumes a STM32F429 chip. -//! -//!

Since the APB1 frequency limit is satisfied now, the system clock source can be safely changed. -//! -//! ```rust,ignore -//! clocks.set_sys_clock_source(SysClockSource::PLL); -//! ``` -//! -//! ## Another example of changing the system clock to PLL for STM32F429: -//! -//!

As an alternative, the AHB prescaler could be configured to change both APB1 and APB2 -//! frequencies. -//! -//! ```rust,ignore -//! // Changing it to 2 wouldn't work, because it would give a frequency of 50MHz for the APB1. -//! clocks.set_ahb_prescaler(APBPrescaler::DivideBy4); -//! ``` -//! -//!
