Example Description

This example describes how to use one DAC channel to generate a signal with noise waves on DAC Channel1 output.

In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 clock is the 2 frequency division of the Main clock, APB2 clock is from Main clock.
