LCD驱动程序开发指南
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。

LCD12864(ST7920)串行驱动程序
0xf8为写命令的命令字；0xfa为写数据的命令字,这里用的是TI_F28027
在编写和调试过程中借鉴了一些网上的程序，在此表示感谢，
这里是已经调好的，在移植过程中，调试时注意先要通过示波器对函数
void send_data(Uint16 D_Ctrl,Uint16 D_data)
void send_data(Uint16 D_Ctrl,Uint16 D_data)
//LCD_CLK一个脉冲写一位
{
Uint16 i,j;
Uint16 temp;
