[原创] FL032-C0 240*320 TFT LCD的AVR驱动程序，LCD控制芯片ILI9320 并行16bit模式
大家好：经过两个晚上的努力，终于用AVR驱动起来这个型号是FL032-C0 控制芯片是ILI9320 的240*320 TFT LCD. AVR芯片用的是M32
当然这个屏最合适用ARM来驱动。16bit总线，很方便的。
这个液晶屏是从二手交易论坛grant那弄来的，grant由于采购错误买了10块，现在还有6块，我刚才又发邮件定了一块。因此最多还有5块，需要的可以去看看。http://www.ouravr.com/bbs/bbs_content.jsp?bbs_sn=823134&bbs_page_no=1&bbs_id=1011
另外这个屏的资料也全在那里。
闲话少说，上程序：
程序1：
用的是M32芯片，编译平台AVRStudio4.13+WINAVR20070525 -s优化级别，16MHz时钟频率
连线：
LCD M32
D0~D7<--->PA0~PA7
D8~D15 <--->PD0~PD7
CS --->PB0
RS --->PB1
WR --->PB2
RD --->PB4
RESET --->PB5
管脚定义在程序中很容易就可以改的，其中控制脚可以任意更改。
程序完成的功能是，把屏分成八份，显示八种颜色，即RGB的排列组合。
然后程序会在中间显示一幅小照片，鉴于M32的存储空间有限，所以图片很小了。
PS：程序没有注释，大家将就着看了。不好意思
这是程序：

效果图：（抱歉，用手机那30W拍的，不清楚）

程序2：
用的是M32芯片，编译平台AVRStudio4.13+WINAVR20070525 -s优化级别，16MHz时钟频率,这次使用SD卡作存储
连线：
LCD M32
D0~D7<--->PA0~PA7
D8~D15 <--->PD0~PD7
CS --->PB0
RS --->PB1
WR --->PB2
RD --->PB4
RESET --->PC0
SD卡 M32
SO ---〉 MISO
SI <--- MOSI
CLK <--- SCK
CS <--- SS
程序完成的功能是搜索SD卡更目录下的batch文件夹下的bin文件。
这个文件是通过img2lcd 3.2软件生成的。选取方式是16位色，包含头数据，水平扫描，bin文件，240*320。
上一个测试程序也是通过这种方式取的，只不过是不包含头数据，弄成c语言的格式。
找到文件后会依次显示到屏幕上。
注：FAT支持FA16和32， FAT12不支持
这是程序：

把那个batch文件及其文件也附上来：（解压到sd卡就可以了，形式：batch文件夹，里面存放bin文件）

程序的说明：
屏是工作在16位并行的模式下的，色彩65K，还没试过262K呢。
在test2中，我对程序作了整理，放在LCM文件夹下，有相应的c和h文件。以便于使用。
这个程序我只完成了初始化，还有就是显示数据。没有那些显示汉字，字母的程序。这个程序只要稍加改动就可应用于你的其他液晶程序。
这个屏的操作思想是：
初始化 （这个我写好了，不需要管了）
写数据：
先确定XY坐标，然后启动，写数据（可以连续写，地址模块自己会自动增加），结束。这个都有相应的函数。
如果中途改变坐标，则需要重新启动，然后写数据。
相信只要这么多，就行了，另外还有读数据，操作方式跟写数据相同
这个屏有个window功能的，就是写数据只写到设定的窗口内，在test1里我之前也用了这个功能，但是发现这个功能要求，x的起始和结束需要是4的倍数。
搞不明白，手册上又没明说，只提到起始x比结束x小，然后，两者的差要大于等于4，莫非就是这个因素？
后来我就没用这个函数，重新写了个。
好了，如果你有这个屏就试一下吧。献丑了。 厉害！ 要是有SPI接口的TFT LCD，用ST CortexM3核的STM32F103xxx的SPI接口，最快可以做到18M的速度，那显示起来才爽啊。
我要的2.8寸快到了，你要是需要预定要早点给我消息。只是价格我暂时也不是特别清楚，我全部委托朋友搞定，我只能保证会控制在200RMB以下，都是那个17点税搞的。 谢谢grant，我回了你邮件了，我要一块，spi接口的线又少。麻烦你了！ 有SPI接口的TFT，我也想要个，呵呵~~ 你的效率好高哈!今天做了它的小板(6.5CM*6.5CM)的.竟用了70远,(5快),物价果然涨了!好在是和同学平分费用的~ 上面的触摸屏没用上，可惜了。
不过这次要是全部转让完了，我就没了。我买的2.8寸屏很快就到了，是用来配STM32F103R8T6，我额外加了一个EN28J60。倒时那个屏也要做转接板，那个插座麻烦，不想焊在PCB上。
to bozai
我收到你的邮件，我会多定购一块。回头我的MCU板做好了，我送你一块空PCB和主芯片，到时你也TFT也不用焊板了。 不知道楼主可否给我订购一个SPI方式的液晶呢 强帖！ 顶下，呵呵 to: Grant
谢谢！
触摸屏没用上是可惜了，一个也要好几十呢。不过以后可以用上。现在没有触摸屏的控制芯片，在21ic上看到有人用avr的ad直接接的不知道性能如何。这倒可以试试。
另外看了你给的资料，那个2.8寸的把所有接口都接出来了，可以根据选择使用spi还是并行方式。看了尺寸图，那个FPC的脚距也很小，焊起来有难度阿。哈哈，等着你的板子了，多谢了！
还有，那个屏的背光不是3.2v而是12.8v，它把四个等串了起来，所以还得加个dc-dc升压电路，这个不难，你做板时要注意了。
to 7楼：
不好意思，屏是Grant的，Grant是自己定购时顺便帮我多带一块的。
PS：这个屏还是有很多脚的，但其可以工作在spi模式下的 to 【9楼】 bozai 章其波
用AVR的A/D做触摸屏性能还可以，我已经测试过了，好像在论坛里有人已经发过了，那我就在发一次我验证通过的。

http://cache.amobbs.com/bbs_upload782111/files_8/ourdev_176170.jpg to 【10楼】 _yu-ming :
谢谢！有空试一下。 to bozai
我已经申请了触摸屏的IC，拿到后我会送你几片，免得触摸功能浪费了。俺别的没有，就是芯片多，特别是MCU。
2.8寸的屏是支持SPI、8位、16位并行方式、YSYNC接口。上面已经说了，我暂时也不知道具体的价格。这块2.8寸屏是不带触摸屏的！
真要需要的，我可以多拿几块。不过这块屏的价格可能会高一些，因为前面的那块2.4寸的时没有开票拿的，后面的这块2.8的要含17点的税。 to Grant:
哈哈，Thanks a lot！
to 【4楼】 cddyy & 【7楼】 RENMA :
还等什么，需要的赶快联系grant哦，是捎带哦，不是卖的。晚了就没了。 呵呵，我的邮箱：cddyy@sohu.com
希望Grant能看到，对了，能发给我模块的资料么？ 留个记号 to：Grant
能否也帮我多定一个SPI的屏呢
谢谢 bozai 章其波 你的触摸屏部分搞好了吗？ 我把M16A/D采集触摸屏的代码已经上传了。 【17楼】 _yu-ming
谢谢！已经下了。
昨天太累了，没试，公司事也比较多。 谢谢bozai的共享，热心会员啊 :) 给我发邮件的几位，我暂时不能答复是否还有剩下的，因为有几个网友订了，但我一直没查到到账，我既然答应了他们，再等一下，下周一之后如果还没确认付款，我只能对他们放弃！到那是我才能知道还能剩下多少块，所以之前有给我发邮件的，我都没有回复。
转让这块屏我是亏了本的，只是没亏那么多罢了。所有不要指望我有很多这样的屏。
to migzan：我当初登出转让消息时，感觉被你挤兑了，就这个价格全新的屏还带触摸屏你还嫌……，我觉得和你交易不会是一件爽快的事情。为了避免你我之间不必要的误会，我只能说非常抱歉，我无法为你提供购买渠道，也许在TaoBao上你会找到更好的机会的。
to cddyy：
由于一些意外，我暂时还不能发给你2.8寸的全部资料。
to bozai：
出了一点意外，今天早上朋友打电话过来，如果2.8寸的含税的话，价格有点高了快接近我的目标。我之前已经订了10pcs，是用在我自己的系统中的，没有多出的数量。我打算叫我朋友在帮我找找有没有可以不用加税的2.8寸或3.2寸屏，当然也要是能支持SPI接口的，要是找不到合适的，就只能再追加定购了。如果有什么消息我再邮件告知你。
哦，对了你对宽屏介不介意？听说现在的2.8和3.2流行宽屏啊？模块的具体尺寸我也不是特别清楚，在等提供数据手册。 to Grant:
无所谓的，都可以。
另外如果找不到合适的，追加订购又比较麻烦的话，那个屏我想就不要找了吧，已经很麻烦你了，呵呵。 to Grant:
等您在这里发消息 to：【20楼】 Grant
你的做事原则我喜欢，你那么想我也不想说什么，一件小事也不想多说了
有论坛这个好氛围，这个好地方，贴点路费我想你也不怎么在乎，没觉得亏了
我曾经帮助过论坛几个哥们在北京中发买芯片，有的没货我去定货，前后跑了几次，不说那点车费，光时间就耽误不少了，不图一点利益，就只因为是论坛的朋友，有共同的爱好。
影响你转让了，说声抱歉，并不是存心或者恶意，事情就此OVER吧，Grant你也不用回我帖了 2.8的屏到了没有？？
想要一块！！！
最好能带STM32F103R8T6的板子！！！
有的话发我条短信：13586540855 ST现在官方给出的Cortex－M3 STM3210B EvalBoard上用的TFT LCD与我之前搞错的TFT使用的是相同的驱动，不过它使用的是SPI接口，而我本身买错的屏只有并行接口。我在STM32演示板下面找到它使用的ILI9320底层驱动，有画点、画园、画线等函数可以参考，如果有帮我转购这个屏的朋友，需要使用的时候可以参考它的部分函数。记得由于接口不同，读、写函数是需要改变的，代码最后的LCD_SPIConfig函数对不是使用STM32F10x芯片控制是没有用的。

我发邮件给你了 不知道楼主的图片是怎样将它的二进制数据查出来的。
要是有软件的话还希望楼主赐小弟一份。
不过楼主的软件中的pgm_read_word（）函数取出来的一个字是高低颠倒的。unsigned char LCD_DrawPicture2(unsigned char startX, unsigned char startY, unsigned int *pic, unsigned char sizeX, unsigned char sizeY)
{
unsigned int i,j,k ,l;
if((startX+sizeX)>240 || (startY+sizeY)>320)return 1;
for (j = 0; j<sizeY; j++)
{
LCD_Set_XY(startX,startY);
LCD_Write_Start();
for(i = 0; i<sizeX; i++)
{
k = pgm_read_word(pic++);
l= k;
k = k<<8;
l =l>>8;
k= k+l ;
LCD_Write_Data(k);
}
startY++;//换行
}
LCD_Write_End();
return 0;

SPI的速度真的可以吗?我看现在用这些屏的手机都是用并行线的啊. 画面不错 弱问搂主：ili9320逻辑电平是3.3，而mega32在3.3v时做大8M晶振，迷惑中。。。。
“用的是M32芯片，编译平台AVRStudio4.13+WINAVR20070525 -s优化级别，16MHz时钟频率” 准备玩tft lcd，标记一下 ili 9320 驱动的TFT LCD 横竖显示任何设置？ 学习 我用M16驱动了一片9320的块，用并行16BIT接口就显示OK
但是改为用8BIT接口就死活无显示。硬件连线上按SPEC上要求IM3:0接成0011，DB口用DB10-DB17，其它DB口全部接地。连线是没有问题了。
一直怀疑写的时序有问题，但同样的写寄存器的时序用在51上就可以正常点亮此屏。十分困惑，请高人指教。十分感谢！

我测试连续读GRAM时，也发现地址不能自动加1。不知你的问题解决了没？还望赐教。 我也网购了一块240*320的.相同的驱劝芯片.
正在实验中...... 波仔出品，必属精品。
哈哈 很好! 程序写的不错 我又块3.2寸的屏，驱动器也是ILI9320的，出现了个问题，
就是在前大约50行写数据什么都很正常，但是后面的就什么也不显示了，
请用过这款屏的高手指点
我连续按单片机复位键，偶尔会出现一次想得到的效果，
我手头有两块一模一样的屏，都这样 楼上可以重点检查一下复位时序和初始化中的几个等待时间。另外，你前50行写数据都正常是写汉字或者图片吗？我也遇到过只显示一部分图片（前几十行）的情况，但显示的图片不正常，感觉被压缩了。 谢谢楼主的程序。
我试了一下。基本可以用。
我将其搬到LPC2458上却出现些问题。
就是不能从XY:00处写数据。写的时候前面有一小部分数据没有显示出来。如果在TEST_LCD的FOR中加入延时则能减少丢失的数据。
当延时达到8000NS时则可以从XY:00处开始写。
后来改动初始化时的值及顺序就解决了。 我修改的程序，驱动液晶ILI9325不太行，楼主有时间帮我看看吗？我的QQ号：498088997 记号 请教大家，我用AVR 8位数据线方式驱动TFT彩屏。8位数据线连接 DB8~DB15,DB0~DB7接地。屏也设置为8位方式了。
使用如下写寄存器函数：
#defineLCD_Reg (*(volatile uchar *)0XE000)
#defineLCD_Data(*(volatile uchar *)0XE001)
void LCD_WR_REG(uint reg16,uint data16)
{
uchar dataH,dataL;
uchar regH,regL;
dataH=data16/256;
dataL=data16&0xff;
regH=reg16/256;
regL=reg16&0xff;
LCD_Reg=regH;
LCD_Reg=regL;
LCD_Data=dataH;
LCD_Data=dataL;
}
初始化完毕后，读取ID寄存的，返回值是不对的，读取时使用
LCD_Reg=0;
LCD_Reg=0;
xx1=LCD_Data;
xx2=LCD_Data;
请教各位，可能会是哪里出了问题。硬件连接方面已经自信检查过； 16位数据分两次发送的 MARK 兄弟，请问下看。我一个屏，用的芯片是HX8347的。它有8位。16位模式。如果我只想用8位传数据应该怎么设置呢。是硬件上设置还是在寄存器里进行设置。应该和你的屏差不多的。说说你是怎么弄的看。行不 请问ＬＳ有没有１６ＢＩＴ模式的程序，我的调不出来。
我看HX8347得规格书有脚设置的，但应该没有引出LCD的接线处。 mark mark 我找了一个搞批发的ILI9320液晶屏+触摸+背光而且还是3.5寸屏才90元，不过是拆机件，3.0、2.8寸的80元全新的。有要的我帮大家搞几片，邮资自费.
