帶中文字庫的128X64是一種具有4位/8位并行、2線或3線串行多種接口方式，內部含有國標一級、二級簡體中文字庫的點陣圖形液晶顯示模塊；其顯示分辨率為128×64, 內置8192個16*16點漢字，和128個16*8點ASCII字符集.利用該模塊靈活的接口方式和簡單、方便的操作指令，可構成全中文人機交互圖形界面?？梢燥@示8×4行16×16點陣的漢字. 也可完成圖形顯示.低電壓低功耗是其又一顯著特點。由該模塊構成的液晶顯示方案與同類型的圖形點陣液晶顯示模塊相比，不論硬件電路結構或顯示程序都要簡潔得多，且該模塊的價格也略低于相同點陣的圖形液晶模塊。 基本特性: 低電源電壓（VDD:+3.0--+5.5V） 顯示分辨率:128×64點 內置漢字字庫，提供8192個16×16點陣漢字(簡繁體可選) 內置 128個16×8點陣字符 2MHZ時鐘頻率 顯示方式：STN、半透、正顯 驅動方式：1/32DUTY，1/5BIAS 視角方向：6點 背光方式：側部高亮白色LED，功耗僅為普通LED的1/5—1/10 通訊方式：串行、并口可選 內置DC-DC轉換電路，無需外加負壓 無需片選信號，簡化軟件設計 工作溫度: 0℃ - +55℃ ,存儲溫度: -20℃ - +60℃ 12864（帶字庫漢字顯示演示程序）

做過一個自行車里程表。上次在群里說起，眾友竊笑 其實也是好玩。4年前2月份到新公司，想知道上班路程到底多遠，做了這 一試，居然單程8公里。不過也不錯，就算健身嘛 最近，天氣已涼，可以常背上相機騎車了。裝上這個里程表吧 單片機AT89C2051，芯片以前作了它用。這次程序重新寫入，久未玩，也頗費了一番工夫

PCF8562是一種能與幾乎所有低復用速率的LCD接口的外圍設備。它為所有靜態和復合的LCD（包含最多4個背極和32段）產生驅動信號。PCF8562與大多數微處理器／微控制器兼容并可以通過兩線雙向的I2C總線通信。通過帶自動增量尋址的顯示RAM、硬件子地址尋址和顯示存儲器切換（靜態和復合驅動模式）可以將通信的開銷降至最低。

關于PCB封裝的資料收集整理. 大的來說,元件有插裝和貼裝.零件封裝是指實際零件焊接到電路板時所指示的外觀和焊點的位置。是純粹的空間概念.因此不同的元件可共用同一零件封裝，同種元件也可有不同的零件封裝。像電阻，有傳統的針插式，這種元件體積較大，電路板必須鉆孔才能安置元件，完成鉆孔后，插入元件，再過錫爐或噴錫（也可手焊），成本較高，較新的設計都是采用體積小的表面貼片式元件（SMD）這種元件不必鉆孔，用鋼膜將半熔狀錫膏倒入電路板，再把SMD 元件放上，即可焊接在電路板上了。晶體管是我們常用的的元件之一，在DEVICE。LIB庫中，簡簡單單的只有NPN與PNP之分，但實際上，如果它是NPN的2N3055那它有可能是鐵殼子的TO—3，如果它是NPN的2N3054，則有可能是鐵殼的TO-66或TO-5，而學用的CS9013，有TO-92A，TO-92B，還有TO-5，TO-46，TO-52等等，千變萬化。還有一個就是電阻，在DEVICE 庫中，它也是簡單地把它們稱為RES1 和RES2，不管它是100Ω 還是470KΩ都一樣，對電路板而言，它與歐姆數根本不相關，完全是按該電阻的功率數來決定的我們選用的1/4W 和甚至1/2W 的電阻，都可以用AXIAL0.3 元件封裝，而功率數大一點的話，可用AXIAL0.4,AXIAL0.5等等?，F將常用的元件封裝整理如下：電阻類及無極性雙端元件：AXIAL0.3-AXIAL1.0無極性電容：RAD0.1-RAD0.4有極性電容：RB.2/.4-RB.5/1.0二極管：DIODE0.4及DIODE0.7石英晶體振蕩器：XTAL1晶體管、FET、UJT：TO-xxx(TO-3,TO-5)可變電阻（POT1、POT2）：VR1-VR5這些常用的元件封裝，大家最好能把它背下來，這些元件封裝，大家可以把它拆分成兩部分來記如電阻AXIAL0.3 可拆成AXIAL 和0.3，AXIAL 翻譯成中文就是軸狀的，0.3 則是該電阻在印刷電路板上的焊盤間的距離也就是300mil（因為在電機領域里，是以英制單位為主的。同樣的，對于無極性的電容，RAD0.1-RAD0.4也是一樣；對有極性的電容如電解電容，其封裝為RB.2/.4，RB.3/.6 等，其中“.2”為焊盤間距，“.4”為電容圓筒的外徑。對于晶體管，那就直接看它的外形及功率，大功率的晶體管，就用TO—3，中功率的晶體管，如果是扁平的，就用TO-220，如果是金屬殼的，就用TO-66，小功率的晶體管，就用TO-5，TO-46，TO-92A等都可以，反正它的管腳也長，彎一下也可以。對于常用的集成IC電路，有DIPxx，就是雙列直插的元件封裝，DIP8就是雙排，每排有4個引腳，兩排間距離是300mil,焊盤間的距離是100mil。SIPxx 就是單排的封裝。等等。值得我們注意的是晶體管與可變電阻，它們的包裝才是最令人頭痛的，同樣的包裝，其管腳可不一定一樣。例如，對于TO-92B之類的包裝，通常是1 腳為E（發射極），而2 腳有可能是B 極（基極），也可能是C（集電極）；同樣的，3腳有可能是C，也有可能是B，具體是那個，只有拿到了元件才能確定。因此，電路軟件不敢硬性定義焊盤名稱（管腳名稱），同樣的，場效應管，MOS 管也可以用跟晶體管一樣的封裝，它可以通用于三個引腳的元件。Q1-B，在PCB 里，加載這種網絡表的時候，就會找不到節點（對不上）。在可變電阻

針對低壓電網中傳統有源電力濾波器（APF）和晶閘管投切電容器（TSC）簡單并聯運行時出現的系統不穩、TSC頻繁投切等問題，提出了一種基于FBD法的統一APF和TSC且共用電抗器的控制方法。該方法只通過一個控制器同時計算出APF的補償指令電流和TSC投切組數控制信號。通過負載電流的變化率dILq /dt判斷負載是否處于暫態過程，來決定是否更新TSC的投切狀態，從而避免TSC的頻繁投切和系統振蕩。共用電抗器的拓撲結構還能節約經濟成本，減小裝置體積。通過仿真實驗，驗證了系統的可行性及有效性，是一種高性價比且性能優良的無功及諧波補償方法。
