You can open the NXP™ FRDM-KL25Z Board block library in two ways.
The MATLAB® Command prompt - this approach is quick, but does not display the other Simulink® block libraries that are available.
In the Command Window, enter: freedomboardrootlib.
Double click on the FRDM-KL25Z block to open the FRDM-KL25Z block library.
Double click on the FRDM-TFC Shield block to open the FRDM-TFC Shield block library.
The Simulink Library Browser - this approach is longer, but displays all of the Simulink block libraries that are available.
