智能手机传感器的数据端口解决方案
智能手机正在成为普及的计算和通信平台。随着每一代新一代智能手机在执行过程和数据密集型应用程序,一旦需要电脑或专用设备得到更好的。现代的多核和多核处理器正在使用几年前所需功率的一小部分来完成实时任务。
智能手机正在取代离散的手持仪器在相同的方式,个人电脑和笔记本电脑取代大,笨重,更昂贵的设备成为了用户界面和流程引擎。在这种情况下,更好的和更快的数据端口之间的插件,插件,或无线传感器/传感器是必要的。
本文探讨了常见的智能手机数据端口,并介绍了如何在工程师可以使用这些解决方案,连接各种传感器和外设,利用,根据需要,智能手机作为一个高清晰度显示,触摸屏,过程引擎,并链接到云。
In the beginning
Early computers used handy serial ports like RS-232 as a de facto standard for linking peripherals and terminals as well as for computer-to-computer connection. Printers, plotters, programmers, in-circuit emulators, and all sorts of common and specialty tools took advantage of serial ports to allow easy and universal connectivity. However, while the popular UART-based RS-232 ports are no longer available on smartphones, serial connectivity is still one way in. The lowest cost and simplest I/O link solution is the audio-in and audio-out ports, which are accessible using a small stereo in/out audio jack. Plugging into a headphone jack for example, provides two (stereo 44.1 KHz) audio outputs, which are capable of reliably passing two independent MODEM streams of data very long distances using low-cost, twisted pair or shielded cables.
