怎样给液晶电视写程序
首先你得有参驱动这个液晶屏的程序，有了程序要有编程器，可以把这个驱动板上的存储IC取下，也可以在线ISp烧录，还要有电脑，基本的 *** 作要会，如果刷错了知道如何判断，就这样
液晶电视写程序怎么写
只需要准备一个U盘就可以更换所有的LVDS接口的液晶屏程序。
U盘升级方法:
把屏所对应的程序复制到U盘中
把U盘插到板上的USB口上
接上按键板,按住按键板上的任意一个按键再通电,直到看到按键板上的指示灯出现红绿交替闪烁后,再松开按键,直到指示灯闪烁结束后,拔掉电源,再拔掉U盘就OK了,重新通电即可
液晶电视怎样写程序
如果你不是做维修的，我建议你不要自己刷，否则有可能废掉主板，刷写程序可不是玩耍玩耍就可以的，得通过专门的程序来刷写，刷写成功，都无所谓，但是刷写失败，若还能刷写成功就成功了，若失败则直接废了，所以慎行啊。
怎样给液晶电视写程序
我卖了个R809F编程器400元，现在只用它改了DVD遥控器，DVD画面，中九。它能读写液晶彩电数据。可写液晶彩电我还没试遇到钉，知道一定告诉你。

如何给液晶电视写数据
维修工具容易买，维修数据难寻啊。以后液晶电视机的内部软件更强大 查看原帖>>
请问液晶电视最简单的刷程序的方法是怎样弄
这个没法刷，除非系统统一升级过。内存太小，一刷就没了

你这个液晶屏不是一般开发板能带有的。大致读了一下：
#include <avr/ioh> #include "boardh" #include "manageh"//调用头文件 #include "scanh" #include "timerh" #include "lcdh"
void sys_init(void);
void bus_reset(void);
int main(void) //主程序
{ uint8_t i = 0; //这里定义了一个计数器，用于指示灯闪烁计时用
sys_init(); //系统初始化，具体程序在下面
int_init(); //又初始化了一个什么东西，先不管
// timer0_init(); //没有用到time0
timer1_init(); //time1初始化，但是就现有程序而言还无法知道计时周期
// timer2_init();
// adc_init();
wdt_disable(); //先禁用看门狗
wdt_enable(WDTO_250MS); //设置看门狗250ms为一周期
wdt_reset(); //复位看门狗
sei(); //禁用中断
// 初始化LCD
lcd_init(); //调用液晶屏初始化程序
while(1) //主程序循环
{ manage(); //应该是处理液晶显示内容用的子程序
if (i & 0x10)
LED_ON(); //0x10个周期后LED闪烁
else
LED_OFF();
i++;
delay_ms(10);
wdt_reset(); //复位看门狗
}
}
// 系统初始化
void sys_init(void) //系统初始化子程序的详细内容（看来只定义了IO口还真不知道这个系统内单片机的定时器如何初始化的）
{
PORTA = 0xf2; //定义IO口
DDRA = 0; // PA7~PA4 键盘输入,PA3: LCD_A0复用电池测量时，输出1
// PA2: 输入,测电池电压, PA1:LCD_CS, PA0:输入，测总线电压？
PORTB = 0xff;
DDRB = 0x00; // PB输出，LCD_DB,PB0~PB4 KEY SCAN
PORTC = 0x80;
DDRC = 0xc0; // PC输出，PC7:LCD_RST,PC6:LCD_LED+,
PORTD = 0x03;
DDRD = 0xf3; // PD7:PWM,PD6:ZL,PD5:ZH,PD4:LED
// PD3返回,PD2开关， PD1:LCD_RD, PD0:LCD_WR
}
void lcd_init(void) //LCD的初始化
{
uint8_t i;
LCD_RST_L(); //应该是复位LCD
delay_ms(2); //延时
LCD_RST_H(); //复位完毕，该复位引脚拉高
for (i=0; i<8; i++) //复位8次看门狗？
{
delay_ms(20);
wdt_reset();
}
write_cmd(0xe2);//system reset 24 //写一个复位命令？
delay_ms(10);
write_cmd(0xeb);//set bias RATIO=1/12 27 =E8 FOR LOW POWER //设置液晶屏偏压
write_cmd(0x81);//set refence voltage ;pm 11 DOUBLE command //设置参考电压
write_cmd(0x83);//set RGB D1 21 //设置RGB方式？
write_cmd(0x2f);//set color mode,65K 22 D4 FOR 256 COLOR 3r-3g-2b//设置彩色显示深度
write_cmd(0x2b);//set line rate,358kps 15 A3//设置啥？不是很明白
write_cmd(0x24);//set n-line 5,TempCompensation 00//设置某种补偿？
write_cmd(0xa2); // 15 set line rate 296k
write_cmd(0xd0);//set partial display 21 D0 BGR//设置一个副屏幕？或许这个彩屏还附带一个小屏幕？
write_cmd(0xd6);//set cen 22 d6 64k color 5-6-5//不明白
write_cmd(0xc0); // 19 LC[2:0]
write_cmd(0xaf); //set display on 18, DC[4:2]=111//仍然不明白
delay_ms(10);
wdt_reset();//重启看门狗
}
void write_cmd(uint8_t cmd)//“写命令”子程序
{
LCD_A0_L();//应该是拉低“命令\数据”引脚的电平
LCD_CS_L(); //片选引脚
PORTB = cmd; //PORTB的8个引脚作为并行口向液晶屏输出数据
DDRB = 0xff; //PORTB的方向定义为输出
LCD_WR_L(); //写LCD引脚电平拉低，看来这程序可能是为了防止被中断或者别的情况打乱，特地发送了两遍
LCD_WR_L();
LCD_WR_H();
LCD_CS_H();
DDRB = 0; //改PORTB为高阻态
//个人觉得后面应该还需要两个语句：LCD_CS_H();和LCD_A0_H();已完成一个“写命令”周期
}
总之，你这块液晶屏应该在市场上不常见。要用这个玩意，你必须有对应这块液晶屏的详细文档、数据手册，否则光这么一个程序很难把这个液晶屏玩转了。
