玩转12864液晶显示图片,画点,画任意直线 通过上一篇的实验,相信大家都掌握了显示字符的基本用法。
下面我们来看一下12864液晶更高级的用法。
首先是它的绘图功能。
让我们先来显示一整副的图片吧,也就是128x64大小。
在使用绘图功能时,先要打开扩充指令集,然后再打开绘图功能。接着就是送数据显示了。这里我们首先要弄明白ST7920的显示坐标关系。其显示坐标如下。 从图中可以看出,X方向共有8个字(16个字节)Y方向共有0~31 行 分为上下两个屏。
弄懂了之后我们就可以依照此坐标来显示一整屏的图片了。
随便用一个图片的提取转换软件,讲一副126X64大小的图片转换成字节数据,总共字节大小为128*64/8 = 1024个字节。 下面我们来看看这个显示整屏图像的函数
void v_Lcd12864DrawPicture_f( unsigned char code *pPicture )
{
unsigned char i, j, k ;
for( i = 0 ; i < 2 ; i++ )//分上下两屏写
{
for( j = 0 ; j < 32 ; j++ )//行
{
v_Lcd12864SendCmd_f( 0x80 + j ) ;//写Y坐标(第几行上写)
if( i == 0) //写X坐标 (判断在那一屏上)
{
v_Lcd12864SendCmd_f( 0x80 ) ;
}
else
{
v_Lcd12864SendCmd_f( 0x88 ) ;
}
for( k = 0 ;k < 16 ; k++ ) //写一整行数据(一行共16个字节,合八个字符)
{
v_Lcd12864SendData_f( *pPicture++ ) ;
}
}
}
v_Lcd12864SendCmd_f( 0x30 ) ;//基本功能设置
} 看看效果图片如下:显示一个人的图像 下面来看看如何在任意一个位置显示或者是擦除一个点 对于12864这种二值显示屏来说,其显示状态无外乎显示和不显示一个点这两种状态。而在任意位置画点,是我们随心所欲的画线,画圆,画矩形的等GUI函数的基础。
为了让这个位置有一个参考点,我们有必要定义一个坐标系
在这里,我定义的坐标系如下
0,0------------------------------------127,0
| |
| |
| |
| |
0,63----------------------------------127,63 0,0代表屏幕的左上角,127,63代表屏幕的右下角。
对于屏幕上面任意一个点,如果我们想要点亮它,必须先读出此点的状态,然后再修改该点,最后送出去,即 读----修改----写。按照这个步骤,然后再运用C语言中的位操作运算符 可以很方便的完成画点的函数。
由于画点函数涉及到读ST7920内部RAM的操作,因此,我们必须先要完成这个读数据的函数
具体实现过程如下:
unsigned char u8_Lcd12864ReadByte_f( void )
{
unsigned char byReturnValue ;
v_Lcd12864CheckBusy_f() ;
io_LCD12864_DATAPORT = 0xff ;
SET_DATA
SET_READ
CLR_EN
SET_EN
byReturnValue = io_LCD12864_DATAPORT ;
CLR_EN return byReturnValue ;
} 然后是画点的函数,其实现过程如下: void v_Lcd12864DrawPoint_f( unsigned char X, unsigned char Y, unsigned charColor )
{
unsigned char Row , tier , Tier_bit ;
unsigned char ReadOldH, ReadOldL ;
v_Lcd12864SendCmd_f( 0x34 ) ;
v_Lcd12864SendCmd_f( 0x36 ) ;
Tier = X >> 4 ;
Tier_bit = X & 0x0f ;
if( Y < 32 )
{
Row = Y ;
}
else
{
Row = Y - 32 ;
Tier += 8 ;
}
v_Lcd12864SendCmd_f( Row + 0x80 ) ;
v_Lcd12864SendCmd_f( Tier + 0x80 ) ;
u8_Lcd12864ReadByte_f() ;
ReadOldH = u8_Lcd12864ReadByte_f() ;
ReadOldL = u8_Lcd12864ReadByte_f() ;
v_Lcd12864SendCmd_f( Row + 0x80 ) ;
v_Lcd12864SendCmd_f( Tier + 0x80 ) ;
if( Tier_bit < 8 )
{
switch( Color)
{
case 0 :ReadOldH &=( ~( 0x01 << ( 7 - Tier_bit ))) ; break ;
case 1 :ReadOldH |= ( 0x01 << ( 7 - Tier_bit )) ; break ;
case 2 :ReadOldH ^= ( 0x01 << ( 7 - Tier_bit )) ; break ;
default :break ;
}
v_Lcd12864SendData_f( ReadOldH ) ;
v_Lcd12864SendData_f( ReadOldL ) ;
}
else
{
switch(Color)
{
case 0 :ReadOldL &= (~( 0x01 << ( 15 - Tier_bit ))) ; break ;
case 1 :ReadOldL |= ( 0x01 << ( 15 - Tier_bit )) ; break ;
case 2 :ReadOldL ^= ( 0x01 << ( 15 - Tier_bit )) ; break ;
default :break ;
}
v_Lcd12864SendData_f( ReadOldH ) ;
v_Lcd12864SendData_f( ReadOldL ) ;
}
v_Lcd12864SendCmd_f( 0x30 ) ;
} 有了画点的函数之后,一切似乎都变得简单了,因为点是一切复杂图形的最基本的组成单位。
下面我们就在这个画点函数的基础上,实现画水平线和垂直线的两个函数。
画水平线:
void v_Lcd12864DrawLineX_f( unsigned char X0, unsigned char X1, unsigned charY, unsigned char Color )
{ unsigned char Temp ;
if( X0 > X1 )
{
Temp = X1 ;
X1 = X0 ;
X0 = Temp ;
}
for( ; X0 <= X1 ; X0++ )
v_Lcd12864DrawPoint_f( X0, Y, Color ) ;
}
画垂直线:
void v_Lcd12864DrawLineY_f( unsigned char X, unsigned char Y0, unsigned charY1, unsigned char Color )
{
unsigned char Temp ;
if( Y0 > Y1 )
{
Temp = Y1 ;
Y1 = Y0 ;
Y0 = Temp ;
}
for(; Y0 <= Y1 ; Y0++)
v_Lcd12864DrawPoint_f( X, Y0, Color) ;
} 下面我们就用以上两个画线函数,在液晶屏上面画一个表格出来
v_Lcd12864DrawLineX_f( 0, 127 , 0, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 7, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 15, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 23, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 31, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 39, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 47, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 55, 1 ) ;
v_Lcd12864DrawLineX_f( 0, 127 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 0, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 15, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 31, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 47, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 63, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 79, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 95, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 111, 0 , 63, 1 ) ;
v_Lcd12864DrawLineY_f( 127, 0 , 63, 1 ) ; 看看显示效果
怎么样,你的实现了吗?
只能画水平线和垂直线似乎太简单和单调点了。
要是能在任意两点间画一条直线就好了,那样我们就可以做很多事情了。
下面就让我们去实现它!
在这里我们采用Bresenham画线算法,关于这个算法,网上有很多资料,请大家以它为关键字到网上去搜索,在这里就不啰嗦了。
下面是算法的具体实现过程:
void v_Lcd12864DrawLine_f( unsigned char StartX, unsigned char StartY, unsignedchar EndX, unsigned char EndY, unsigned char Color )
{
int t, distance; /*根据屏幕大小改变变量类型(如改为int型)*/
int x = 0 , y = 0 , delta_x, delta_y ;
char incx, incy ;
delta_x = EndX - StartX ;
delta_y = EndY - StartY ; if( delta_x > 0 )
{
incx = 1;
}
else if( delta_x == 0 )
{
v_Lcd12864DrawLineY_f( StartX,StartY, EndY, Color ) ;
return ;
}
else
{
incx = -1 ;
}
if( delta_y > 0 )
{
incy = 1 ;
}
else if(delta_y == 0 )
{
v_Lcd12864DrawLineX_f( StartX, EndX,StartY, Color ) ;
return ;
}
else
{
incy = -1 ;
} delta_x = ABS( delta_x );
delta_y = ABS( delta_y );
if( delta_x > delta_y )
{
distance = delta_x ;
}
else
{
distance = delta_y ;
}
v_Lcd12864DrawPoint_f( StartX, StartY, Color );
/* Draw Line*/
for( t = 0 ; t <= distance+1 ; t++ )
{
v_Lcd12864DrawPoint_f( StartX,StartY, Color ) ;
x += delta_x ;
y += delta_y ;
if( x > distance )
{
x -=distance ;
StartX +=incx ;
}
if( y > distance )
{
y -=distance ;
StartY +=incy ;
}
}
} 老规矩,我们用这个函数随便画任意斜率的几条直线看看。
v_Lcd12864DrawLine_f( 0, 0, 127, 63, 1 ) ;
v_Lcd12864DrawLine_f( 0, 63, 127, 0 , 1 ) ;
v_Lcd12864DrawLine_f( 12, 0, 127, 63, 1 ) ;
v_Lcd12864DrawLine_f( 52, 63, 127, 0 , 1 ) ;
v_Lcd12864DrawLine_f( 32, 63, 98, 0, 1 ) ;
v_Lcd12864DrawLine_f( 67, 0, 127, 63 , 1 ) ; 下面是具体的效果图:
要能画波形,有一点是至关重要重要的,那就是打点,所谓打点,就是能在指定的X,Y的坐标处打上一个小黑点,12864液晶的操作就像大多数16位以上的处理器一样是字节或字或双字操作的,不像51和彩色液晶一样的位操作,所以要在12864上打点,就必须用“与或”的方式。下面把打点的函数贴上,这是以前做温度波形显示的时候做的 /****************打点******************/
void point(uchar x,uchar y)
{
uchar y1,hang,lie,m***_data,l***_data,temp=0x01;
if(y1!=y)
{
m***_data=0;
l***_data=0;
}
y1=y;
if(y<32)
{
hang=0x80+y;
lie=0x80;
}
if(y>31)
{
hang=0x80+y-32;
lie=0x88;
}
if(y>63)//return;
{
lcm_com(0x80);
_nop_();
hanzi("温度超出显示范围");
while(1)
flash();
} lie=lie+x/16; if(x%16==0)
{
m***_data=0;
l***_data=0;
} if(x%16<8)
{
m***_data=m***_data|(temp<<(7-x%16));
l***_data=0x00|l***_data;
}//保留以前的数据,把第x个点亮
if(x%16==8)
{
m***_data=m***_data|0x00;
l***_data=l***_data|0x80;
}
if(x%16>8) 大于24小于32
{
m***_data=m***_data|0x00;
l***_data=l***_data|(temp<<(15-x%16));
}
lcm_com(0x34);//扩充指令集
lcm_com(hang);
lcm_com(lie);
lcm_dat(m***_data);
lcm_dat(l***_data);
lcm_com(0x36);//绘图显示开
}
打点完成之后波形就相应的出来了,比如说要记录一个波形随时间变化,x坐标随着时间自动增加,x增加一个单位时相应y的值就得确定,在送个打点函数,波形就出来了。这是一种实时波形 还有一种波形,比如正弦,余弦,等等数学波形,可以添加math.h这个头文件。然后里面相应的函数得到x,y的关系,就能画出这个波形了,下面把正弦波的函数贴出来 /**********正弦波*********/
void fsin()
{
float x,y;
uchar x1,y1;
for(x=0;x<(4*3.1415);x+=0.1)
{
y=sin(x);
x1=10*x;
y1=31-(10*y+0.5);
point(x1,y1);
}
} y1=31-(10*y+0.5);这条语句是对y值进行四舍五入! 在网上找了很久都没带字库12864画点波形显示程序,全是不带字库的,于是自己动手修改了一个。 只是在前一个驱动程序上加了俩子函数。 #include
