Demo Owner: Derek Snell   This demo combines several solutions from NXP and our partners. The demo is a thermostat application, using the Kinetis family as a communication gateway between a ZigBee network and connecting to the cloud. The demo runs on the MQX Real-Time Operating System (RTOS). It also uses the NXP PEG graphics library for the user interface displayed on an LCD. The ZigBee communication uses NXP’s BeeStack ZigBee stack, and connects with an NXP wireless development board programmed as a remote temperature sensor. The demo will also connect with an off-the-shelf ZigBee light bulb, and wirelessly controls it. The demo network connection is setup for Wi-Fi, using a Wi-Fi module from Qualcomm. The cloud connection allows the thermostat to be monitored and controlled remotely with mobile devices, and uses a solution provided by deviceCloud.io.     NXP Products Product Link Shield Adapter Module for the Tower System Shield Adapter Module for the Tower System | NXP  Kinetis® KW2x Tower System Modules TWR-KW2x|Tower System Board|Kinetis® MCUs | NXP  Kinetis K70 120 MHz Tower System Module TWR-K70F120M|Tower System Board|Kinetis MCUs | NXP  Serial (USB, Ethernet, CAN, RS232/485) Tower System Module Serial (USB, Ethernet, CAN, RS232/485) Tower System Module | NXP  Graphical LCD Tower System Module with RGB Interface Graphical LCD Tower Module with RGB Interface | NXP    Design Resources Getting Started Guide Development Tools Thermostat Demo Software Firmware updated to v1.0 on 9/9/14      - DCIO Cloud agent now uses SSL from WolfSSL.  This improves WebSocket connections to cloud server through some protected networks.

Linux kernel is not real time OS, while some applications is time sensitive tasks running in Linux environment, this request to extend the real time feature in common Linux kernel, and RT_PREEMPT is one of the methods to enable Linux kernel with real time processing requirement. But RT_PREEMPT is not accepted by kernel, so it needs extra effort to porting this patch-set to i.MX8M family products. This patch-set is based on L4.14.78 for i.MX8M products, customer need to apply patches based on this release.
