This post entry provides a detailed description of how a Bluetooth Low Energy (BLE) pairing solution via NFC was developed using two of our reference development boards: The NTAG I 2 C plus kit for Arduino pinout The Freedom KW41Z board. This document has been structured as follows: NFC for easy one-tap pairing solution NFC pairing is one popular feature you can find in cameras, speakers, printer, routers, wearables and many more. Just bringing two NFC-enabled devices close together is all it takes to create a connection. Just to mention a few of examples, with just a swipe you can: Connect your phone to a wireless speaker. Connect your new devices to the home network. Connect accessories to the control unit. In all these scenarios… NFC and Bluetooth are a perfect combination, since the pairing process with NFC becomes: Faster compared to the traditional pairing methods. Easier, reducing technical support More reliable, making sure you connect to the right device. The technical basis for this “tap to connect” process is provided in the NFC Connection Handover specification running atop the NFC Forum protocol stack. It defines a framework of messages and data containers that allow bootstrapping of alternative (i.e., other than NFC) carrier connections in a standardized way. For this reason, NFC pairing solution offers a unified user experience and interoperability across different manufacturers.  NFC solutions to implement secure simple pairing There are two types of solutions recommended to add NFC pairing functionality to designs: NFC static pairing with NTAG 213 The first solution is embedding an NTAG 213 NFC label. In such a case, the pairing credentials need to be previously loaded in to the tag memory as well as in the device MCU during manufacturing. NFC dynamic pairing with NTAG I2C plus The second solution is embedding an NTAG I 2 C plus tag. In such a case, the pairing credentials can be dynamically updated by the device MCU during the product lifetime. In addition, other features such as an automatic wake-up field detection signal are possible. Precisely, the combination of a passive NFC interface with a contact I2C interface allows the product to behave as a tag and be read via NFC and to connect to a host or application processor via  I 2 C. In addition, NDEF messages can be generated and updated by the host MCU depending on the application requirements. Later, these NDEF messages can be read by any NFC phone, including iOS devices with the latest OS version. Hardware setup Mapping the previous diagram to the demo hardware, we have: The NTAG I 2 C plus tag, using the Arduino pinout kit The MCU, using Kinetis KW41Z. The applicatiob logic, which updates the NDEF contents based on different use cases. Some details about the hardware used in the next sections: Kinetis KW41Z The Kinetis KW41Z is a high integrated chip with multi-protocol radio features enabling Bluetooth Low Energy (BLE) and 802.15.4 radio protocols such as Thread. KW41Z has as large memory of 512KB that can support multiple radio protocols running in a single application instace and implements nine low-power modes and a wide operating voltage range (0.9V/4.2V), for optimum current consumption. Finally, the software support package includes: BLE, Thread and 802.15.4 generic network stacks, several sample demo apps, support for RTOS and full integration in MCUXpresso. The Kinetis KW41Z evaluation is supported with the FRDM-KW41Z development board. The board main components are: a reference crystal, an accelerometer, an Arduino header, some LEDs and buttons, a JTAG and OpenSDA connectors,and an external flash memory. NTAG I2C plus kit for Arduino pinout The NTAG I 2 C plus Arduino kit consist of two PCBs stacked together: The upper PCB is the antenna board with the connected tag The lower PCB is an interface adaptor board to the Arduino pinout. This kit can be used to connect and evaluate the NTAG I 2 C plus  into many popular MCUs with Arduino compliant headers, for example:  Kinetis (e.g. KW41Z, i.MX (e.g. UDOO Neo, i.MX 6UL, i.MX 6 ULL, i.MX 7D) and LPC MCUs (e.g. LPCXpresso MAX, V2 and V3 boards). The kit support package includes several software examples, including the BT pairing example based on KW41Z.  The OM29110ARD is a generic interface board which offers support for connection to any PCB implementing Arduino connectors. It exposes: 3.3V and 5V power supply pins. I 2 C , SPI and UART host interfaces. Generic GPIOs (e.g. to be used for field detect, interrupts, reset pins or others) As such, it allows the NTAG I 2 C plus to be plugged into Arduino devices seamlessly. Once the NTAG I 2 C plus  board is stacked on the KW41Z, the pining routing between the two boards is as follows. It uses:  The  I 2 C  interface pins. The 3.3V supply pin. One GPIO is routed for the field detection pin. The Vout, for the energy harvesting pin. The ground reference. BLE pairing with NFC on KW41Z and NTAG I2C plus This section details how the Bluetooth Low Energy (BLE) pairing with NFC on KW41Z and NTAG I 2 C plus works. The following block diagram is a simplified representation of the demo that shows: The Bluetooth and NFC interfaces The buttons and LEDs involved in the process. Starting BLE advertising After SW4 is pressed: The application goes from IDLE to searching mode, advertising the BLE device The LED 3 starts blinking in RED color. Writing BLE pairing NDEF message Once the BLE advertising is activated, the next step is for the KW41 to write the pairing message into the NTAG I 2 C  plus memory. After SW3 is pressed: The KW41 uses the  I 2 C interface with the NTAG I 2 C plus to load a pre-defined NDEF message with the BLE pairing details. At the same time, the LED 4 is set to GREEN. Pairing with the BLE device While the LED 4 is set to green, the BLE pairing message is exposed through the NTAG I 2 C plus  RF interface. During this interval, any NFC-enabled device: Can read out the NDEF pairing message. Pass the BT credentials to the Android system or the host processor. And automatically create a Bluetooth link according to the exchanged network credentials. In case of an Android system, no third-party implementation is needed on this part as long as the pairing message follows the NFC Forum specifications. Writing default NDEF message Once the pairing information is read out of the NTAG I²C plus, the KW41Z removes the pairing content and turns back to normal operation mode. In addition, in this specific demo, the NDEF pairing message is programmed to remain in the NTAG I²C plus memory for only ten seconds. After these 10 seconds: The green LED is switched off. And the pairing NDEF message is overwritten by the default NDEF about the NTAG I²C plus demo app. Video The following video shows how the Bluetooth Low Energy (BLE) pairing with NFC on KW41Z and NTAG I 2 C plus works. How to integrate NTAG I2C plus into FRDM-KW41Z hid_device sample project In this section, we describe, step by step, how NFC is integrated in an existing default demo application taken from the KW41Z support package.   FRDM-KW41Z startup In the board website, there are very clear instructions on how to get started www.nxp.com/demoboard/FRDM-KW41Z. For instance: How to test KW41Z. How to get the tools, in our case: MCUXpresso, and the SDK for KW41Z. How to import, build and runn the examples included in the SDK for KW41Z, in our case: the ones inside the wireless_examples folder Importing FRDM-KW41Z SDK and hid_device sample project After that, we import the FRDM-KW41Z SDK and we import the sample project used as a basis for adding NTAG I 2 C plus support, this is the hid_device example located under the wireless/Bluetooth folder. Importing NTAG I2C plus middelware The NTAG I 2 C plus  middleware can be easily imported as a new folder in the project tree using the MCUXpresso File / Import menu. Once imported, the internal structure of the middleware should have this structure: HAL_I2C: The HAL_I2C files support access to the Kinetis I 2 C interface. HAL_ISR:  The HAL_ISR files support the interrupt handling and callback registration for the Kinetis MCU. HAL_NTAG: The HAL_NTAG source files provide an API that allow you to communicate with the NTAG chip and implements the NTAG command set to perform memory access operations from the I 2 C interface.  For instance, this API can be used to perform: Read / Write memory operations on EEPROM and SRAM (for example, to read data, you just need to indicate the memory address and length of the data to be read) Read / Write access to NTAG I 2 C plus registers (for example, you just need to indicate the register macro to be read). Functions for enabling the pass-through mode and handling the data exchange between interfaces (setting the data transfer direction is as easy as using this function). HAL_TMR: The HAL_TMR files support access to the timing hardware of the Kinetis MCU. Adding / changing GPIO pin settings All pin and GPIO settings are defined within the pin_mux.c file. For our application, the I 2 C pins need and a GPIO for the field detection need to be enabled.  Regarding the host interface: the I 2 C  pins for NTAG communication are configured using the BOARD_InitI2C() function, it sets the required I 2 C  port (port 0 for this MC) and set the right mode for the clock (SCL) and data (SDA) lines. Regarding the field detection: it is defined within the source code even though it is not used so far. It is left defined for future use. Within the pin_mux.c file, there are other functions which initialize; for instance, the buttons, LEDs, etc. These functions are called during the hardware initialization. NTAG I2C plus software and hardware initialization We move to the main_application, where some pieces of code need to be added. All code that has been added, is inside the #ifdef NTAG_I2C clause. First, we added: The I 2 C_driver and the ntag_app header files . The ntag_handle handler declaration. Then, the HW initialization is performed calling I2C_initDevice and the NFC_Initdevice() function is called to fill the  ntag_handle software handler. HID_device demo extensions The BLE demo application is written in the hid_device.c file and the whole behavior is handled in this file. The C-code printout in the blue box  below shows the content of the BleApp_HandleKeys() function, which handles the BLE activity and the changes made related to the NFC use case. Similarly, all new code additions are within the #ifdef NTAG_I2C clause. Mainly, the BleApp_HandleKeys() function function was extended to: Copy the pairing NDEF message to the NTAG I 2 C plus chip when the button SW3 is pressed. Set the LED 3 to green while the pairing NDEF message is available. Start a timer counter from the moment the SW3 button is pressed In addition, when the time counter is expired (expiration was defined to 10 seconds): The memory content of the NTAG I 2 C plus chip is overwritten by default NDEF message. The LED 3 is set to off. NDEF message for BLE pairing definition The last part missing to cover the NFC integration into the KW41Z refers to the files created within the application to declare the NDEF pairing and NDEF messages. The NFC Data Exchange Format (NDEF) is the NFC Forum specification defining an interoperable, common data format for information stored in NFC tags and NFC devices. The spec also details how to enable tags to deliver instructions to an NFC device so that the device will perform a specific action when a particular tag is read (open a browser, initiate a phone call, pairing, etc.). Every NDEF message can be automatically processed by any NFC device and execute the appropriate action without requiring the installation of any customized software / application and independently of the hardware manufacturer. There are several NDEF record formats that you can use in your implementation. Each NDEF record indicates to the application processor which kind of payload the message carries. In our demo app, the default NDEF message used belongs to a smart poster record and the NDEF pairing message, follows the protocol defined in the NFC Forum connection handover specification. Going to the source code, two application files for the NDEF handling were created: The app_ntag.h declares the two NDEF messages used in this demo. The app_ntag.c, implements a function which writes the NDEF message into the tag. As mentioned, the NDEF used for this BLE pairing was built according to the Connection Handover and BT secure simple pairing specifications and rules. On the image below, we copied the declaration of the NDEF pairing message. This is actually the hex bytes that are written into the tag memory. To highlight son relevant parts: We find the capability container and the NDEF TLV. These two fields are used by the NFC device to detect if the tag is loaded with NDEF formatted data into a Type 2 tag (like the NTAG I 2 C plus). After that, we find the record type name. This is the MIME type for the Bluetooth out of band pairing (written in its ASCII representation). It is followed by the device Bluetooth MAC address, and the complete local name (Freescale HID). The terminator TLV In case you are interested to know more about the NDEF message structure, you can check the NFC Forum specifications The data (MAC address 00:04:9F:00:00:04 & device name FSL_HID) read by the NFC device is sent to the Bluetooth controller to establish the Bluetooth connection. Default NDEF message definition  The NDEF used as thedefault_ndef message consist of two records: The first record was built according to the SmartPoster specification from the NFC Forum, which describe how to store a plain message followed by an URL. The second record is what is called Android Application record. On the image below, we copied the declaration of the NDEF default message. To highlight son relevant parts:   As the NDEF BLE message, the first data fields we find correspond to the container and the NDEF TLV structure for a Type 2 Tag. Then, we find the smart poster record, which includes a text field. In this example, it codes the text “NTAG I2C Explorer”  and a URI field which codes a the NTAG Explorer kit website URL. After that, we find the Android application record, which is used to automatically launch the app  or, if the app is not installed, redirect the user to Google Play. Finally, the terminator TLV. After 10 seconds, the application removes the BLE pairing NDEF and replaces it by the above described NDEF message. This can be easily demonstrated by tapping the phone after these 2 seconds, and validate that the NTAG I 2 C plus demo is automatically opened.

PMSM/BLDC motor are excellent choices for many appliances and industrial applications that require low cost and high-performance variable speed operation This design will employ sensorless FOC to control a PMSM and a sensorless algorithm to control BLDC The hardware design supports both motor types with the algorithms fully implemented digitally via software running on the 56F8013 DSC Features General: For PMSM the motor control algorithm employs Field-Oriented Control (FOC). The power stage switches are controlled by means of Space Vector Pulse Width Modulation (SVPWM) The feedback hardware elements are limited to the motor stator phase currents and the bus voltage. No position information devices or stator flux measurement are used; sensorless speed methods are employed The Motor is capable of forward and reverse rotation and has a speed range of 500rpm to 6000rpm The user controls motion profiles, rotation direction, and speed.

         LittleVgl作为一款开源免费的嵌入式GUI得到越来越多工程师的厚爱，我们可以看到很多小型HMI项目或者一些开源社区都在使用它作为GUI的框架，同时也受益于用户群的不断扩大以及一些半导体原厂的青睐（通俗点就是说有赞助有钱儿了），LittleVgl本身也在快速的不断更新迭代，易用的组件和相关的辅助开发工具在不断的增加，而RT1050/1060/1170系列作为一款带有LCD控制器的平台，自然成为了LittleVgl最佳的载体之一了。         LittleVgl本身的组件已经很丰富了，但是遗憾的是一直没有加入对中文输入法Keyboard的支持（看了下它在Github上的Contributor List没有华人），这让它在我们国内的应用有了一些限制（注意在某组件上显示中文和真正的中文输入法是不同的概念），所以本项目旨在解决该问题，即把一个简单轻量的中文输入法框架嵌入到LittleVgl并跑在RT1050平台上，并把它开源开放出来，所以不要小看了我的“公益心”，哈哈。下图是该示例设计的UI界面        下面进入正题，首先把测试环境给出来，方便有兴趣有能力的朋友可以自行搭建（当然应一部分偷懒的强烈需求，我随本文档也附赠了完整的移植好的工程），然后我再一步一步地给出如何移植这套框架到用户自己的工程里，当然我已经把代码本身做了很多优化，尽量减小环境依赖，力求最少步骤的移植过程，理论上来讲不太会出现移植后编译出一堆Error的问题，咳咳。。。下面我们赶紧开整吧： 测试环境： SDK版本：SDK_v2.9.1 SDK参考例程：boards\evkbimxrt1050\littlevgl_examples\littlevgl_demo_widgets LittleVgl版本：v7.4.0 IDE工具：Keil_v5.31 开发板：MIMXRT1050-EVK + 480*272 RGB LCD屏 软件说明： 我们先看下这套中文输入法所需的几个文件，如下图所示，.c和.h文件加起来一共7个，其中nxp_logo.c只是我额外加的一个NXP的官方logo图标转成的C数组文件供littleVgl调用显示，属于锦上添花的东西，可有可无，真正跟输入法相关的是剩下的6个文件，下面我们逐一介绍下这几个文件的作用： 1. qwerty_py.c/.h：        实际上这两个文件才是这套全键盘拼音中文输入法的核心框架，实现了对输入的拼音字母进行索引匹配对应的汉字候选列表，这部分我是移植了如下链接中网友分享的代码，所以这两个文件我的角色只是一个大自然搬运工，不过说实话我是很感激该网友的无私分享的（这也是我一直推崇开源分享精神的源动力），之前对平时使用的各种输入法里面的算法原理一直充满好奇，直到看了这篇文章后才豁然开朗，“So that is what it is!”，让我获益匪浅（可能人的学习曲线和知识体系就是这样一点一滴的积累吧），而且更关键的是，如果让我继续往下开发诸如拼音联想和多汉字输入等功能的话，我更多关心的可能只是逻辑搭建的工作量问题，而不是纠结于Yes or No的问题了，因为咱已经了解了其最底层的工作原理了，所以很多复杂的事情，我们如果能抽丝剥茧的找到其最底层的本质（虽然这真的很难），那很多让人抓耳挠腮的问题很快就可以理清思路。说到这里我思维又发散了，呵呵，我想起让Linus Torvalds等一波老大神们一直头疼的Linux内核维护后继无人的问题，其实我的个人理解有很大一部分原因是如今的Linux太庞大了以至于几乎没有后辈的人对Linux的理解能赶上这些老辈大神，而这些老辈大神的最大优势是他们创建了Linux最早期的底层框架而且难能可贵的是一直在follow Linux每个版本的历史。总之，推荐大家看看如下这篇文章吧（实际上主要内容也都是代码），希望能各有所获； https://www.amobbs.com/thread-5668320-1-1.html?_dsign=0939dcbd 2. lv_chs_keyboard.c/.c文件：        这部分就是我的工作了（咱也不能啥都搬运…，这是体现咱的value的东西不是），我把它当作littleVgl的一个补充组件来写的，里面的大多数API参考官方littlevgl的lv_keyboard.c，所谓的文章开头的嵌入中文输入法到LittleVgl GUI环境中实际上就是这两个文件干的活，即将上面提到qwerty.c/.h实现的拼音输入法与LittleVgl框架结合到一块，起到一个桥梁的作用，所以如果你想把这套中文输入法嵌入到其他GUI环境中的话（比如emWin，GUIX，TouchGFX等），那主要的工作就是参考这两个文件的内容了； 3. lv_font_NotoSansCJKsc_Regular.c字体文件：        虽然littleVgl官方源码包里自带了一个中文字体文件（\lvgl\src\lv_font\lv_font_simsun_16_cjk.c），但是它只包含了1000个左右最常用的字，我实际体验了下很多我们想用的字都找不到，所以这个时候就需要自己去做一个更全一点的字体库了。这里面涉及到两个问题需要考虑，第一是很多我们常见的中文字体是收费的（咱PC机的Microsoft Office套件里的中文字体都是微软付费买的，所以咱也理解下早年正版Windows为啥辣么贵了，那你问为啥现在便宜了？因为人家现在不靠这个赚钱了呗），第二个是字体转换工具的问题，我们网上找到的字体都是TTF或者OTF格式的，但littleVgl是不认的，需要转换成它支持的字体格式。        对于第一个问题，我网上搜了好久最终选择了目前用的比较多的Google开源免费的字体，Google真乃金主也，它维护的网站里面字体各种各样啥都有且是开源免费的，如下链接，我选择的是NotoSansCJKsc字体（最后面的sc表示simplified Chinese，简体中文），然后它里面又包含了各种字形（regular, bold, light等），可以根据需要自行选择，整个包很大（100多MB），拆分成不同字形的就小了（每个14~16MB左右）； https://www.google.com/get/noto/        对于第二个字体转换工具的问题，LittleVgl官方自带了一个字体转换工具（online font converter）,我个人觉着不太好用（对OTF字体支持的不行），这里推荐阿里大神自己做的一个LittleVgl字体转换工具（LvglFontTool），非常方便好用，且支持加入Awesome图标； http://www.lfly.xyz/forum.php?mod=viewthread&tid=24&extra=page%3D1        关于字体这部分我需要再补充个问题，就是它占用的memory大小，毕竟我们是在嵌入式MCU平台Flash和RAM的资源是受限的，如下图所示，该字体文件占用大概1Mbytes的rodata空间（即可寻址的Flash空间，当然该大小可以通过在上图转换工具中增减一些文字来调 整），所以在移植本套输入法之前需要预留足够的Flash空间，当然对RT平台来说这部分还好，毕竟其本身就外扩至少几MB空间的QSPI Flash作为存储空间的。 4. lv_demo_chineseinput.c/.h文件：        这两个文件属于应用层实现了，主要关注该文件中下图的ta_event_cb函数（即textarea事件的callback，点击文本框的输入时回调），在里面我们需要按照1，2，3去调用即可（这三步的API均在lv_chs_keyboard.c/h文件里实现）；        至此，这套全键盘拼音中文输入法框架所需的几个文件就介绍完了，用户只需要把这几个文件放到自己的工程设置好文件搜索路径，并参考随本文档附带的代码工程示例，再结合自己产品的GUI样式，把这套中文输入法嵌入到自己应用当中。
