anactrl_measure_frequency#

Overview#

The anactrl_measure_frequency Example project is to demonstrate usage of the KSDK anactrl driver. In the example, you can set a reference clock and target clock. The project will calculate the frequency of the target clock according to the reference clock frequency.

Supported Boards#
