Design of small tft - lcd driver circuit 驅(qū)動電路的設計
Meanwhile , the measuring and result can be displayed at real time on a lcd which is driven by a special lcd driver 同時該系統(tǒng)利用專用lcd驅(qū)動器將測量過程和結(jié)果實時地在lcd上進行顯示。
Thirdly , we designed the client software . in this portion , we designed ethernet card driver software of s3c4510b 、 protocol service software and lcd driver software 在這一部分中,主要介紹了s3c4510b網(wǎng)卡驅(qū)動程序的設計、協(xié)議服務軟件的設計、液晶顯示模塊的軟件設計; 4
The peripheral controller consists of frequency detector , data sample controller , fifo , lcd driver and the interface circuit between dsp and fpga 外圍控制器囊括了硬件系統(tǒng)中幾乎所有的數(shù)字電路,包括頻率/周期測量、數(shù)據(jù)采集控制、 fifo 、 lcd驅(qū)動以及fpga與dsp之間的接口電路等。
Semisilicon was established in may 1995 . our business mainly focuses on ic planning , design , production , and sale . our main products have el driver ic , led control ic and lcd driver ic etc . all these products can be used generally on computer peripheral and consumer products 矽誠科技成立于1995年05月,主要系從事ic半導體設計規(guī)劃、制造及銷售,目前主要的產(chǎn)品包括有冷光片驅(qū)動ic 、 led控制ic等產(chǎn)品,這些產(chǎn)品可以廣泛地應用于消費性或電腦周邊產(chǎn)品上。
High voltage drift drain mosfets ( dddmos ) are nowadays widely applied in circuits of power management , i / o interface , lcd drivers and etc . however , up to now a lack of a standard and accurate dddmos current model still brings much trouble in the circuit design 近年來,高壓雙擴散漏器件dddmos ( driftdrainmosfet )以其優(yōu)良的性能被廣泛地應用于電源管理、輸入輸出接口、 lcd驅(qū)動等電路中。然而,目前在業(yè)界缺少標準和準確的dddmos電流模型,給電路設計者帶來困難。
Its hardware design was analyzed from the master module , imported equipment modules , exporting equipment modules , data storage module , other components and the problem of the printer ’ s continuous printing from interrupted position was fixed in this course ; followed by , the software design including the operating system and the application software was discussed . the kernel of linux system was transferred to the motherboard of the novel fiscal cash register as its own operating system , in which the compilation of lcd driver and the printer driver was mainly focused on , and the application software was divided into the controlled tax software , the commercial software and power - fail protected disposal software for further discussion ; finally , the systemic reliability , security and electromagnetic compatibility were evaluated 首先硬件部分主要由主控模塊、輸入設備模塊、輸出設備模塊、數(shù)據(jù)存儲模塊等部分組成,在硬件設計中解決了發(fā)票打印機掉電續(xù)打的難題;接著對稅控收款機的軟件設計主要從操作系統(tǒng)和應用軟件兩個方面討論:操作系統(tǒng)采用的是linux操作系統(tǒng),先將linux內(nèi)核移植到稅控收款機主板上,著重介紹了lcd 、打印機驅(qū)動程序編寫;應用軟件分為稅控軟件、商業(yè)軟件和掉電處理程序來討論;最后,對本文設計的稅控收款機系統(tǒng)的可靠性、安全性和電磁兼容性等方面進行分析和研究。
A typical calculator chip from rcl semiconductor inc , c9821 , is referenced and developed . the chip of the calculator consists of several function units such as rc oscillator , power management module , microprogrammed control unit ( mcu ) , register group , lcd driver and keyboard interface 在硬件方面,在完成計算器的功能模塊劃分的基礎上,對包括rc振蕩器、電源模塊、 lcd顯示驅(qū)動模塊、鍵盤接口、寄存器組、微程序控制器在內(nèi)的各個功能模塊的系統(tǒng)結(jié)構(gòu)和電路原理進行了分析,掌握了它們的設計方法。
