Overview   As gaming application needs real time, quick and fast reaction, user would like to have low latency solution for gaming application. Existing BT solution has higher latency. Also power consumption is critical in the design with limited battery capacity. NXP’s gaming headset solution combined with low latency and lower power consumption than competitors. We provide two platforms. One use KL27 MCU and the other one use LPC5528 MCU as processor. The key different feature between these two MCU platform is the audio resolution support. KL27 platform supports 48K sampling rate and LPC5528 platform supports USB audio up to 96K sampling rate. We design USB dongle and headset side solution, either module or Arduino interface H/W design. Also PMIC is important in the headset side. NXP can provide MCU, BLE and PMIC for this application.

Overview The FAA now requires drone owners to register any device weighing more than 0.55 lbs. (250 g). For drones currently in the field, enforcing this new law might be problematic, as it relies on the honor system to some extent. But for new devices, NXP offers an easy enforcement method. How it Works NXP’s drone registration solution uses low-cost NFC technology to easily enforce compliance. Manufacturers could include an NFC reader within the drone housing. NXP makes this step straightforward by providing reference designs for drop-into-place design ease. Upon registration, consumers could receive an official government-issued registration certificate that comprises an NXP encrypted NFC tag in adhesive label form. Upon adhesion to the drone housing, the drone control electronics would wirelessly read the certificate. If valid, the drone microcontroller enables functionality. If not, the drone will not power up. Benefits Electronic registration provides more than just ease to government regulatory bodies, it also facilitates regulation of that drone to ensure the safety of all citizens. Upon application of the registration certificate sticker, the NFC chip inside the sticker could convey identification information to the drone microcontroller, such as the registration number, model/serial number of the drone, and its zoning classification. Because this information would now be housed with the drone, drone manufacturers could choose to broadcast select details, such as the classification information, via appropriate long-range wireless communication while in flight. If the drone flew within restricted airspace (near airports, sensitive government sites, stadiums, large public events, etc.), flight controllers could obtain the classification information (something virtually impossible to obtain visually) from the drone and thereby verify its authority (or lack thereof) to travel within a particular space, in order to help prevent potential catastrophes.   Block Diagram   Recommended Products Category Products Features RFID MIFARE DESFire EV2 | NXP  Contactless interface compliant with ISO/IEC 14443-2/3 A Fast data transfer: 106 kbit/s, 212 kbit/s, 424 kbit/s, 848 kbit/s   CLRC663 plus family | High-performance NFC frontends | NXP  Supports NFC Cockpit and NFC Reader Library RF standard compliance: ISO/IEC 14443A and MIFARE, NTAG ®  and SmartMX ®  families Drone PX4 Robotic Drone FMU | RDDRONE-FMUK66  Proven business-friendly open source software with available enterprise support: PX4, QGroundControl Supports all airframes: Use it for Quadcopters, Hexacopter, VTOL, planes, rovers, cars, and other robots Rapid-IOT to Drone adapter board Rapid-IOT to Drone adapter board  Adapter board fully designed for Rapid IoT Prototyping Kit UAVCAN communication between drone and Rapid IOT Works with PX4 flight controllers such as RDDRONE-FMUK66 or Pixhawk NXP Rapid IoT Prototyping Kit Rapid IoT Prototyping Kit  Expandable to most IoT end-node use cases with 400+ Click boards™ Multiple sensors (Gyroscope, Acc/Mag., Barometer/Temp., Air Quality, Ambient light and capacitive touch)

         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。
