There is a demo that looks a useful starting point for anyone developing low power applications:
\KL05-SC\klxx-sc-baremetal\src\projects\low_power_demo
but no pre-built binary and no visible instructions for building this in CodeWarrior for a FRDM-KL05Z.
Any tips?
IMHO it would be very useful if someone could convert this into a Processor Expert project....
Alternatively, are there other CodeWarrior projects that provide working examples of putting a KL processor into the low power modes? It is a key feature of the hardware but I have not so far found working examples of power management.

Hi Charles,
My suggestion would be to make a copy of the LED_Blink program in the KL05 sample code and simply remove the LED_Blink sources and add the sources for the low power demo that you want.
But if you are using Processor Expert, there is a Processor Expert low power demo in the KL25_SC package that you could use as a starting point. That package can be found under the downloads section of www.freescale.com/frdm-kl25z.
Hope this helps,
Chris
Hello Charles,
have you get to tried this suggestion? Did it work?
Please keep us posted :smileywink:
Best regards,

Hi Monica
I was able to build a working demo for the FRDM-KL25Z to allow me to get my head around the clock modes. It is incomplete, but did allow me to move to one of the very low power modes (LLS) and back again with both a timer and a switch wakeup event.
I am happy to share this, and can send the zipped project file if you like.

Charles,
that is just great! :smileygrin:
I'm happy too to see it worked out! Is up to you if you'd like to share your project, I would do it in a separate discussion or even Create a Document, but as I said, is up to your decision.
Thanks for the update!
Best regards,
Monica.
Hi Monica
I have copied the project here:
https://dl.dropboxusercontent.com/u/472780/LP_Test4.zip
It's over to you whether you use it or not. If you do then you might
want to polish it, add it to your existing app note AN4503 etc.

Hi Charles
Would you have a more complete version of the LP_test project that you could share with me?
I am going through the AN4503 right now; looked a little bit at your project and I liked what I saw.
When I mean more complete I am wondering if you had a chance to implement the VLLSx cases:
case VLLS3:
printf("Not yet implemented.\n");
break;
case VLLS1:
printf("Not yet implemented.\n");
break;
case VLLS0:
printf("Not yet implemented.\n");
Thanks, Ioan
