How to change the clock freq of FRDM-KL05Z

[zz642040273]

Hi,

I am using the MBED online compiler to program the MCU, but how do I set a lower clock frequency in order to reduce the power?

Best,

Hi @zz642040273 

Not using mbed, but you can easily do this with the Freescale/NXP Kinetis Design Studio and Processor Expert in the Cpu and Clock settings:

You can easily configure all different low power modes and switch between them:

If using mbed, you can look at the code which is used for this.

I hope this helps,

Erich
