Hello Kinetis users!   I thought this would be the best place to share this code.  Attached is an example of how to use the power manager in the 1.0.0 release of the Kinetis SDK.  It is essentially the legacy low power demo ported to the SDK.  Now, the SDK doesn't provide functions to de-initialize the pins so some of it is a little messy, but it should still help to show you how to use the power manager and how to get in and out of low power modes.    The supported platforms are:   FRDM-K22F FRDM-K64F TWR-K22F120M TWR-K64F120M TWR-KV31F120M   To install the demo, simply unzip the file to the "demos" folder of your SDK installation.  All of the links in the demo are relative so you shouldn't have any trouble.  However, if you do experience any issues, please let me know so that I can correct the issues.    To run the demo, simply build and download the application (a guide of how to do this is provided in the device specific User's Guide in your SDK installation).  Then perform a power-on reset (you always want to do that when working with low power applications) and connect a terminal utility with the following settings:   - 19200 baud rate - 8 data bits - No parity - 1 stop bit - No flow control   Then follow the on-screen instructions.    As a reminder to those wishing to understand low power operations and the Kinetis devices a little more, we do have an Application Note out there to help explain low power operations:  AN4503 Power Management for Kinetis and ColdFire+ MCUs.  This Application Note is in the process of being updated with Kinetis SDK information and is scheduled to be re-published sometime this year.    Enjoy! Chris

Because I receive feedback from customers, that it is sometimes complicated to execute this demo, I created short tutorial how to set it and execute it in KDS 3.0.0.   1. Physical connection In case of TWR-K64F, is needed TWR-SER and correctly set jumpers. and for TWR-K64F is needed to set jumper J6 to pins 1 and 2.   Be sure, that the TWR-SER and TWR-K64F is correctly connected (by white line) 2. Network configuration For changing IP address, please go to Network and Sharing Center, choose Change adapter settings Right click on Properties and change the IP address (TCP/IPv4) to 192.168.2.100   3.  Downloading the demo to TWR-K64F Go to KDS, File - Import and browse the demo, which is located at C:\Freescale\KSDK_1.2.0\examples\twrk64f120m\demo_apps\web_hvac\web_hvac_mqx\kds Import all libraries and the demo project and see imported sets in Project Explorer Debug the libraries first and then the project. Be sure, what debugger is used on the board and set the debugger. And now go to Resume!   4. Test the connection Go to cmd and ping to 192.168.2.102 (address of HVAC Server)   5. HVAC Web Server.Go to browser and type the address 192.168.2.102, you will see page for HVAC Web Server. Go to HVAC Demo - HVAC Status and now you can observe the temperatures by pressing button. There are set combinations which means see below. LED1: Simulate the Fan’s state LED2: System in the Heat mode LED3: System in the Cool mode LED4: Simulate the heart beat, increase real temperature (i.e., by hair dryer) to see the LED4 go faster and decrease temperature to see it slow down. So, if is needed increased temperature, push the first button (SW1) and Fan and Heat mode run. LED1 and LED2 will be light on and the temperature will increase.   Enjoy! Iva
