#include <ioCC2530.h> #include "LCD.h" void main() { //unsigned char i=0; LCD_Init(); //oled 初始化 LCD_CLS(); //屏全亮 LCD_welcome(); while(1) { } }
首先呢。我们运行这个程序，然后可以看到在LCD屏上显示如下图像。第一行显示，你好这是这四个字，第二行显示协调器这三个字。第三行显示的是一个字符串，第四行显示的也是一行字符串。那么这是如何实现的呢？首先我们打开main函数，可以看到在main函数里面有三个函数，这个代码的最主要的一部分就是LCD_welcome，这个函数里面的内容就是我们显示出来的内容，我们对这个函数进行修改，就能在LCD上显示出我们想要的内容。
lcd.h文件
LCD_P16x16Ch函数
/*****************功能描述：显示16*16点阵 显示的坐标（x,y）****************************/ void LCD_P16x16Ch(unsigned char x, unsigned char y, unsigned char N) { unsigned char wm=0; unsigned int adder=32*N; // LCD_Set_Pos(x , y); for(wm = 0;wm < 16;wm++) // { LCD_WrDat(F16x16[adder]); adder += 1; } LCD_Set_Pos(x,y + 1); for(wm = 0;wm < 16;wm++) // { LCD_WrDat(F16x16[adder]); adder += 1; } }
LCD_P8x16Str函数
/*******************功能描述：显示8*16一组标准ASCII字符串 显示的坐标（x,y）****************/ void LCD_P8x16Str(unsigned char x, unsigned char y,unsigned char ch[]) { unsigned char c=0,i=0,j=0; while (ch[j]!='\0') { c =ch[j]-32; if(x>120){x=0;y++;} LCD_Set_Pos(x,y); for(i=0;i<8;i++) LCD_WrDat(F8X16[c*16+i]); LCD_Set_Pos(x,y+1); for(i=0;i<8;i++) LCD_WrDat(F8X16[c*16+i+8]); x+=8; j++; } }
LCD_welcome函数
转到welcome这个函数的定义，我们可以发现它处于LCD.H文件里。现在我们找到LCD.H文件。代码粘贴到下方了，现在跳转到下方的代码处进行进一步说明。
现在我们看到LCD_welcome函数。由于LCD屏上显示的是四行，可以看到，在我们LCD_welcome函数里面也是主要有四个输出。其中两个是在for循环里面被函数调用。另外两个是直接通过函数调用。
这两个被调用的函数都不一样，他们的定义的代码就写在上方。第一个P16X16CH函数。的功能是显示汉字，第二个P8x16STR函数的功能是显示字符串。我们在分别看这两个函数里面的共同点和不同点，他们的共同之处都是调用了一个LCDSetPOS函数和调用了LCD-wrdat函数，但是呢，他们的不同点在于传到LCD-WRDat函数的参数是不同的数组。
void LCD_welcome() { int i=0; for(i=0; i<4; i++) { LCD_P16x16Ch(16*i+32, 0, i); } for(i=0; i<3; i++) { LCD_P16x16Ch(40+16*i, 2, 4+i); } LCD_P8x16Str(16, 4, "QQ:1366449519"); LCD_P8x16Str(32, 6, "2020-5-18"); }
去观察代码可以发现。LCD杠P16X16CH函数和LCD杠P8x16STR函数。里面的前两个数是坐标的意思，第一个数是横坐标，第二个数是纵坐标，而且。它们的纵坐标。每一行都间隔二。他们的横坐标可以更改字体的位置。对于我们前两个设置汉字的位置的坐标来说，它这个横坐标就是汉字的第一个坐标。从这第一个坐标之后开始写入数字，那么我们就要考虑第一个坐标的位置在哪儿，然后再放下一几个坐标的话，他们整体上是呈现出一种什么样的整体样式。我们这里三个字的话，第一个坐标就是40加16乘以i。也就是说，他第一个坐标是位于40。这么画就说明他前面是空出来了40的间距，这样的话三个字整体上看起来就好像是居中了一样，可见字体的位置呢，就是通过x和Y来进行调整。
我们还可以看到，在P16X16CH函数里面的第三个变量是i，这i就相当于我们目前写的第几个汉字。我们之所以把它分开，是因为那是第一行和第二行，为了看的更清晰，可以看到i呢，是连续的，没有说第一行，从零到三之后，第二行就再继续从零开始写。第二行是从四开始写的。
codetab.h文件
转到数组的定义可以看到他们两个不同的数组都在同一个文件中，这个文件就叫code tab文件。然后我们可以看到在F16X16数组里是一系列的字体对应的点阵。在F8x16数组里面，对应的是一系列字符的点阵。
那么现在我们再次回到LCD杠welcome函数里面，我们来看看我们是如何显示这些。特定的字符串以及特定的汉字的。
