0. 80MHz system clock

This example shows how to set up the STM32 microcontroller to execute at its faster clock speed of 80MHz.

Achieving this speed requires two things:

  1. Setting up the Phase-Locked Loop (PLL) to multiply a source clock up to 80MHz.
  2. Configuring flash wait-states to ensure that the processor does not execute faster than instructions can be fetched.

Once the system clock is set to 80MHz, the Microcontroller Clock Output (MCO) is configured to output the system clock over pin PA8. This output can be viewed with an oscilloscope to confirm the clock's speed.

See main.c for comments describing the configuration steps in more detail.
