关键词：BMP图片；SD卡；ARM微控制器；STM32；片上系统第一章绪论1.1本课题设计的背景随着国民经济的起飞，现代社会的不断进步，广告的在新时期又有了新的发展。

进入新世纪LCD显示屏的技术和产业都取得了长足的发展，作为重要的现代信息发布媒体之一，LCD显示屏在证券交易、金融、交通、体育、广告等领域被广泛的应用。

0.96寸OLED显示屏使用手册一、OLED简介OLED，即有机发光二极管（Organic Light Emitting Diode）。

OLED 由于同时具备自发光，不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异之特性，被认为是下一代的平面显示器新兴应用技术。

LCD 都需要背光，而OLED不需要，因为它是自发光的。

这样同样的显示OLED效果要来得好一些。

以目前的技术，OLED 的尺寸还难以大型化，但是分辨率确可以做到很高。

在此我们使用的是0.96寸OLED显示屏，该屏有以下特点：1）0.96寸OLED有黄蓝，白，蓝三种颜色可选；其中黄蓝是屏上1/4部分为黄光，下3/4为蓝；而且是固定区域显示固定颜色，颜色和显示区域均不能修改；白光则为纯白，也就是黑底白字；蓝色则为纯蓝，也就是黑底蓝字。

2）分辨率为128*643）多种接口方式；OLED裸屏总共种接口包括：6800、8080 两种并行接口方式、3线或4 线的串行SPI 接口方式、IIC 接口方式（只需要 2 根线就可以控制OLED 了！），这五种接口是通过屏上的BS0~BS2来配置的。

4）本屏开发了两种接口的Demo板，接口分别为七针的SPI/IIC兼容模块，四针的IIC模块。

两种模块都很方便使用；希望大家根据实际需求来选择不同的模块。

二、产品特点2.10.96寸OLED裸屏外观裸屏为30pin，从屏正面看左下角为1，右下角为30；在设计的时候一定要注意不要搞反了。

具体的接口定义请大家查看0.96寸OLED官方数据手册；里面有详细介绍。

6800系统监控接口通信协议1. 范围本通信协议适用范围是指CSU与监控PC间之通信协议。

2. 依据本通信协议是依据中国电信总局1999年3月「通信局（站）电源、空调及环境集中监控管理系统前端智能设备通信协议」之「开关电源系统通信协议」订定。

3. 定义与符号3.1监控模块– SM（Supervision Module）设备监控模块，此即CSU（Chroma 6802、Chroma 6803）。

3.2监控单元– SU（Supervision Unit）指局站监控计算机（PC）。

4. 监控内容6800系统是属于整流配电设备监控内容可分为三部份：交流屏（交流配电单元）、整流器、直流屏（直流配电单元）。

4.1交流屏（交流配电单元）遥测：三相输入电压、三相输入电流。

遥信：三相输入过压/欠压，缺相，开关状态。

4.2整流器遥测：整流器输出电压每个整流模块输出电流。

7. 信息类型及协议的基本格式7.1. 信息类型信息分两种类型：（1）由SU发出到SM的命令信息（简称命令信息）。

（2）由SM发出到SU的响应信息（简称响应信息）。

常见液晶驱动控制芯片详解前言因此各位朋友在选择LCD液晶模块的时候，在考虑到串行，还是并行的方式时，可根据其驱动控制IC的型号来判别，当然你还需要看你选择的LCD模块引脚定义是固定支持并行，还是可选择并行或串行的方式。

一、字符型LCD驱动控制IC市场上通用的8×1、8×2、16×1、16X2、16X4、20X2、20X4、40X4等字符型LCD，基本上都采用的KS0066 作为LCD 的驱动控制器。

二、图形点阵型LCD驱动控制IC2.1、点阵数122X32—SED1520。

2.2、点阵数128×64。

（1）RA8816，支持串行或并行数据操作方式，内置中文汉字字库。

（2）KS0108/RA8808，只支持并行数据操作方式，也是最通用的12864点阵液晶的驱动控制IC。

（3）ST7565，支持中行或并行数据操作方式。

（4）S6B0724，支持中行或并行数据操作方式。

（5）RA6963，支持并行数据操作方式。

2.3、其他点阵数如192×64、240×64、320X64、240X128 的一般都是采用RA6963驱动控制芯片。

2.4、点阵数320X240，通用的采用RA8835 内置ASCII字库，以及RA8806驱动IC内置ASCII和中文等字库。

这里列举的只是一些常用的，当然还有其他LCD 驱动控制IC，在写LCD 驱动时要清楚是哪个型号的IC，再到网上去寻找对应的IC 数据手册吧。

后面我将慢慢补上其它一些常见的。

三、12864 液晶的奥秘CD1601/1602和LCD12864 都是通常使用的液晶，有人以为12864是一个统一的编号，主要是12864 的液晶驱动都是一样的，其实12864只是表示液晶的点阵是128*64点阵，而实际的12864 有带字库的，也有不带字库的：有5V电压的，也有3.3V工作电压：归根到底的区别在于驱动控制芯片，常用的控制芯片有RA8816、KS0108/RA8808、RA6963等等。

RS485通信标准自从上世纪80年代以来，以其传输距离远、抗干扰能力强、布线成本低等优点，在工业控制领域中得到了广泛应用[1]。

工业领域中的PLC 、变频器、电能表等设备大多采用RS485通信标准，为了方便用户实时监测这些设备的状态信息，设计了一种RS485通信标准的显示屏，可以读取工控设备的状态信息并实时显示到显示屏上，在工控领域有着广阔的应用空间。

1 系统硬件设计系统硬件组成框图如图1所示。

如图1所示，工控设备通过RS485接口把数据传输至MCU ，MCU 将数据解包后，得到需要显示的数据，如果数据中包含文字则会从字库芯片中查找字模，最后将数据显示到12864液晶屏上[2]。

1.1 MAX3485通信芯片MAX3485是MAXIM 公司生产的一款3.3V 供电的RS485电平收发芯片，静态电流仅300uA ，最高可达到2.5Mbps 传输速度，使用广泛。

MAX3485应用电路如图2所示。

MAX3485的2脚和3脚是使能管脚，低电平为接收状态，高电平为发送状态，因此2脚和3脚可以短接，仅需MCU 一个IO 口即可控制。

1.2 STC12LE5A60S2单片机芯片STC12LE5A60S2是STC 公司生产的一款3.3V 供电的单时钟/机器周期（1T ）的MCU 芯片，指令集和管脚兼容传统8051单片机（如图3所示），速度比传统51单片机快6~12倍，在工业控制，强干扰场合比较适用。

本系统运行中涉及到字库读取、字模运算等操作，对MCU 运算性能要求高，因此速度快性能强的STC12LE5A60S2是系统正常工作的保障。

LCD的接口简介（8080模式）
整理人：雨山2013-01-10
一般的lcd简介当中都会出现这么几个词，lcd的接口为16位的80并口，那么什么是16位的80并口呢？
其实，80并口全称为8080并口协议是有因特尔公司提出的，除8080接口协议外还有摩托罗拉的6800接口协议，其不同在于控制器，如下
8080是通过“读使能（RE）”和“写使能（WE）”两条控制线进行读写操作6800是通过“总使能（E）”和“读写选择（W/R）”两条控制线进行
很多MCU或者LCD模块外部接口一般采用并行方式,并行接口接口线的读写时序常见以下两种模式:
(1)8080模式。

这类模式通常有下列接口信号:
/RES（复位线），DB0~DB7(双向数据线),Ｄ/Ｉ（数据/指令选择线，1:数据读写,0:命令读写），CS（片选信号线，如果有多片组合,可有多条片选信号线）,/WR（MPU 向LCD写入数据控制线）,/RD（MPU从LCD读入数据控制线）；
(2)6800模式。

在这种模式下,/RES、DB0~DB7、D/I的功能同模式(1),其他信号线为:R/W读写控制(1:MPU读, 0:MPU写)。

E,允许信号(多片组合时,可有多条允许信号线)。

M68是摩托罗拉的标准接口，I80是英特尔的标准接口。

0.96寸OLED显示屏介绍0.96 寸OLED 显示屏使用方法（以中景园电子的0.96 寸OLED 显示屏为例）0.96寸OLED显示屏实物图七针SPI/IIC 0.96寸OLED显示屏使用方法：七针SPI/IIC 0.96寸OLED显示屏共有七个管脚，1～7 分别为GDN、VCC、D0、D1、RES、DC、CS。

此模块支持四线SPI、三线SPI、IIC 接口。

0.96寸OLED显示屏裸屏是支持五种不同接口的，除了前面的三种还有6800、8080 并口方式；由于这两种接口占用数据线比较多；而且不太常用，所以模块在设计的时候没有引出来。

模块的通信接口是通过BS0,BS1,BS2三个管脚来配置的。

在SPI 接口中，R1,R2,R8 三个电阻是不焊接的。

在IIC 接口中，需要将R3换到R1上，R8 可以焊接也可不焊接。

七针SPI/IIC 0.96寸OLED显示屏正面丝印如下，如果想用IIC接口，在IIC接口中需要将RES接高电平，可以与VCC对接,使OLED复位脚一直操持高电平，也就是不复位的状态；同时需要将DC,CS 接电源地；IIC 通信中只需要GND ,VCC,D0(时钟信号)，D1(数据信号)四根线。

如果感觉比较麻烦；也可以直接选用四针的IIC接口的0.96寸OLED显示屏。

四针IIC接口相对比较简单一些，只有两个信号线。

1、GND：电源地。

2、VCC：电源正（3～5.5V）。

3、SCL：OLED 的D0 脚，在IIC 通信中为时钟管脚。

4、SDA：OLED 的D1 脚，在IIC 通信中为数据管脚。

LCD驱动程序开发指南LCD驱动开发指引1、LCD驱动概述LCD驱动程序调试，是整个⼿机研发过程中⾮常重要的⼀个环节，在每个新的机型开发的初期，最先都要调试LCD驱动程序，我们俗称“点屏”。

“点屏”的调试包括两个部分，⼀是点亮LCD的背光，⼆是调试LCD显⽰。

背光驱动调试的⽅法与技巧，会在背光⽂档中叙述，暂不在这篇⽂档⾥讨论，本⽂将重点讨论LCD的电路原理、驱动程序分析、LCD驱动调试经验总结和具体驱动调试案例的分析。

2、LCD原理及电路分析相关概念：LCD：全称是Liquid Crystal Display 液晶显⽰屏LCM：全称是Liquid Crystal Module指的是液晶显术模块，包括液晶屏及液晶的外围FPC电路和结构件。

LCD的FPC电路：指LCM模块中的液晶外围电路，这部分电路由LCD模组⼚家按照我们对LCD的接⼝要求进⾏设计的。

在LCD驱动调试中，看FPC电路图也是很重要的⼀个环节。

LCD外围电路：我们通常也简称为LCD电路，指的是baseband端的LCD接⼝电路部分，这部分电路由我们⾃⾏设计。

LCD模组⼚家：指信利，天马，京东⽅这些⼚家。

他们将LCD制作成可以供我们⽣产使⽤的LCM模组。

2.1LCD芯⽚介绍⽬前⼿机使⽤的⼤部分显⽰器件都是LCD（Liguid Crystal Display）器件，⽬前康佳使⽤的LCM模块由信利、京东⽅、天马、凌达这⼏家⼚商供货。

但是LCM⽣产⼚家对我们调试驱动并没有任何关系，我们需要了解的是LCM所使⽤的IC型号。

因为，我们实际上是对LCD的IC进⾏编程，间接控制LCD⾯板，常⽤的IC有HD66773、S6B33B2/ S6B33B6、HD66777等。

LCD驱动的编程，除了要关注IC的型号，还要关注LCD FPC的电路设计，LCD外围电路设计，基带芯⽚的LCD接⼝单元，背光IC的控制等⼏个⽅⾯，当然也包括软件的上层程序。

下⾯我们就先了解⼀下LCD IC的内部结构，这是编程要关注的最主要⽅⾯。
