鼓捣了一晚上搞出一个基于原子哥LCD库V3.0的画坐标系图象的几个函数。
使用方法如下：
- void LCD_Plot_Init(u16 width, u16 height, u16 xUnit, u16 yUnit, u16 xOrigin, u16 yOrigin, u8 GridSwitch); //最后一个参数GridSwitch用来设置是否画栅格
- void RefreshPlot(u16 NewValue); //直接输入一个数就可以画图了
支持函数有
- typedef struct tagPlot_Init
{
u16 xOrigin;
u16 yOrigin;
u16 xUnit;
u16 yUnit;
u16 height;
u16 width;
u8 GridSwitch;
} Plot_Init;
void DrawFrame(Plot_Init PLOT_INIT); //用来绘制坐标系的外框
void DP(u16 x,u16 y,u16 color); //快速画点 其实就是给LCD_Fast_DrawPoint()套了个壳
以上部分定义在lcd.h中 在lcd.c中定义了两个全局变量，数组PLOT_NUM[]用来存放显示数据和坐标系参数结构体PLOT_INIT
具体实现代码如下
void DP(u16 x,u16 y,u16 color)
{
LCD_Fast_DrawPoint(x,y,color);
}
void LCD_Plot_Init(u16 width, u16 height, u16 xUnit, u16 yUnit, u16 xOrigin, u16 yOrigin, u8 GridSwitch){//×ø±êϵ³õʼ»¯

PLOT_INIT.width=width;
PLOT_INIT.xOrigin=xOrigin;
PLOT_INIT.yOrigin=yOrigin;
PLOT_INIT.xUnit=xUnit;
PLOT_INIT.yUnit=yUnit;
return;
}
void DrawFrame(Plot_Init PLOT_INIT){
u16 i;
//PLOT_INIT.width=width;
if(PLOT_INIT.GridSwitch){
for(i=PLOT_INIT.width/PLOT_INIT.xUnit;i>0;i--){
