MCU簡化觸覺和段液晶為基礎(chǔ)的用戶界面設(shè)計(jì)

　　許多基于MCU的產(chǎn)品使用觸摸和一個(gè)簡單的LCD輸出來實(shí)現(xiàn)用戶界面設(shè)計(jì)的消費(fèi)，工業(yè)和家電應(yīng)用。這些設(shè)備的例子都在我們身邊：恒溫器，鬧鐘/時(shí)鐘，心率監(jiān)視器，葡萄糖監(jiān)視器，計(jì)算器，電子玩具，安全系統(tǒng)，多米，微波爐，洗衣機(jī)/干衣機(jī)，等等?，F(xiàn)代MCU集成專用硬件的功能來簡化這些類型的設(shè)計(jì)實(shí)現(xiàn)，包括觸摸傳感器接口和段型液晶控制器。

　　為了幫助工程師實(shí)現(xiàn)基于這些功能的用戶界面，還提供了軟件功能，軟件庫，參考設(shè)計(jì)，有針對(duì)性的開發(fā)工具和開發(fā)板廣泛的生態(tài)系統(tǒng)。本文概述了一些最重要的硬件功能，你需要實(shí)現(xiàn)觸摸感應(yīng)（電阻和電容觸摸），以及基于段的LCD控制。從支持生態(tài)系統(tǒng)的一些關(guān)鍵要素的例子也被描述，以幫助選擇一個(gè)特定的用戶界面設(shè)計(jì)的最佳解決方案。

　　Segment LCD Control

　　MCUs are used in just about every piece of equipment that drives a segment-oriented LCD display， due to their low-operating power and programming flexibility. Even MCUs with 8-bit CPUs have the needed computation power and general-purpose interfaces required by many designs. The Freescale MC9S08LC60 adds some special purpose features that further simplify the implementation of segment-based LCD user interfaces. A quick overview of some of these key LCD controller features is a good baseline for evaluating and comparing similar features in other devices.
