Overview The reference design demonstrates sensorless control of the 3-Phase Switched Reluctance (SR) motor using 56F80x or 56F83XX Digital Signal Controllers. It can also be adapted to 56F81XX Digital Signal Controllers. The concept of this application is that of a sensorless speed closed loop SR drive using flux linkage position estimation. An inner current loop with PI controller is included. The change in phase resistance during motor operation due to its temperature dependency creates errors in the position estimation and significantly affects the performance of the drive. Therefore, a novel algorithm for on-the-fly estimation of the phase resistance is included. The Digital Signal Controller runs the main control algorithm. Rotor position is evaluated using the sensorless flux linkage estimation algorithm. The actual flux linkage is calculated at the rate of the PWM frequency and is compared with the reference flux linkage for a given commutation angle. When the actual flux linkage exceeds the reference, the commutation of the phases is done; the actual phase is turned off and the following phase is turned on. Flux linkage error is used for estimation of the phase resistance at low speeds (US Patent No.: 6,366,865). The actual speed of the motor is determined using the commutation instances. Based on the speed error, the speed controller generates the desired phase current. When the phase is commutated, it is turned on with a duty cycle of 100%. Then, during each PWM cycle, the actual phase current is compared with the desired current. As soon as the actual current exceeds the desired current, the current controller is turned on. The current controller controls the output duty cycle until the phase is turned off (following commutation). Finally, the 3-Phase PWM control signals are generated. The procedure is repeated for each commutation cycle of the motor.

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.

Winners! NXP received a number of creative submissions over the course of the MRFX Design Challenge. We appreciate the enthusiasm from the community as designers were hard at work on their RF projects. Now is the moment everyone's been waiting for as NXP proclaims the MRFX Design Challenge winners. First Place Winner  Russell Kendrick | Bio + Full Project Description Project Video: MRFX1K80H 50 MHz Project Brief This amplifier is intended to be driven with a modern transceiver with 100 watts output on 50 MHz. To protect the MRFX1K80H from overdrive a series of RF pads are used to reduce the input to the proper level. The input matching is accomplished by using a 9:1 conventional RF transformer formed on an Amidon BN 61-202 core. An 82 nH inductance is in series with the high impedance winding of the transformer. This arrangement yielded an input match of 1.3:1 SWR over the entire 6-meter Amateur band when measured without the pads. Shunt gate resistance is used to prevent oscillation at low frequencies. This is the same approach used in the 27 MHz test circuit from NXP. Bias will be supplied by a DAC driven by the microcontroller that will manage the finished amplifier Second Place Winner        Floris Roosen | Bio                                                                         Project Video: Roosen Single-Ended Broadband (87-110 MHz) RF Design         Third Place Winner Mike Mysliwiec | Bio Project Video: 2xMRFX1K80H 1.8-54 MHz HF Amplifier   Overview  NXP is hosting an RF power amplifier design contest.

Overview   Artificial intelligence, and machine learning specifically, is transforming industries from Consumer to Industrial. To date, many applications host AI/ML inferencing on conventional computers in the cloud or locally. Meanwhile, edge computing is enabling other computing workloads to move from conventional information technology (IT) to lower-cost systems close to where data is generated. Although many AI/ML workloads run fine on edge systems’ CPUs, others are more intense: either multiple AI/ML functions must run simultaneously or performance requirements (e.g., frame rates) are too great. The solution to gaining the combined benefits of AI/ML and edge computing is acceleration. At the 2020 Consumer Electronics Show, NXP demonstrated the LS1046A-FRWY platform simultaneously running two or more high-intensity AI/ML functions. These include face recognition, object detection (both general and safety gear), posture recognition, and gaze detection. The scenario demonstrated is factory safety. An operator within a safety zone is monitored for attentiveness, personal protective equipment, and access control. Helping to make this possible is external acceleration based on the Google Edge TPU. Interfacing to the Layerscape LS1046A processor via its copious PCI Express ports, two M.2 TPU cards slotted in the FRWY system offload AI/ML inferencing. Based on the Layerscape LS1046A processor with four powerful Arm Cortex-A72 CPU cores, the compact, cost-effective LS1046A-FRWY platform gives developers a leg up on implementing high-performance AI/ML applications at the edge.   Diagram     Products Product Name LS1046A Freeway Board | NXP  Related Community Documents Document Name NXP Helps Industrial System Developers Apply AI/ML to Their Designs  Five Easy Steps To Deploy Machine Learning On Layerscape 

Overview The Bluetooth® Low Energy heart rate monitor reference design demonstrates the implementation of a wireless electrocardiogram (ECG) acquisition system. It features the Kinetis® KW40Z system on chip (SoC) which includes an Arm® Cortex® M0+ processor together with a 2.4 GHz radio for Bluetooth Low Energy and 802.15.4. The ECG signal is obtained from the finger tips and processed by the Kinetis KW40Z SoC. Then, the user’s heart rate is calculated and transmitted to a smartphone application using Bluetooth Low Energy. The reference design can be powered by a Li-Ion coin-cell battery. Due to the low-power features of Kinetis KW40Z MCU, a 3.6V 200mA/h Li-Ion coin-cell rechargeable battery can provide the power of up to 40 hours of continuous use. The NXP® MC34671 is in used as a battery charger solution for the device. Features Includes the NXP ®  ultra-low-power Kinetis ®  KW40Z SoC Bluetooth Low Energy/ZigBee platform. The low-power features of this solution allow up to 40 hours of continuous operation using a small coin-cell battery.
