裸奔程序在屏幕上显示变量数据的可行性
大家好，我是用TQ2440ARM板在裸奔运行自己写的一些程序。为了在屏幕上显示汉字我自己建立了汉字库，并实现了汉字的显示。但是现在想在屏幕上显示数据，即阿拉伯数字。关键是这数字是个变量，可能是10到100，每次结果不确定的。这可怎么显示？我的想法是将数字也放到汉字库里，用循环比较来确定这个变量到底是多少，然后再输出。但这样貌似很麻烦。请高手指点指点。 搞了一下午搞出来了。思路就是将0到9也写入到字库里去。（注意：数字通过汉字取模工具时取出来只有16个数字，要修改其点阵大小使其与汉字一样，然后再修改像素位置，将数字显示在中间部分，以取得更美观的效果）由于我要显示的变量位数不超过3位，我将此变量i/100得到的结果显示就是百位，将i%100再除以10就得到十位，再显示出来，以此类推。。。程序长了些，不过终于实现我要的功能了，呵呵。 你 很 能 搞 2# xiao_menghan自己制作的字库？
制作出来让网友们使用感受一下呀 由于我现在用这个做毕业设计，程序现在还不方便全给出来。我的程序全是在test程序的基础上改出来的。上面说的字库，我是用汉字取模软件将我要用到的几个汉字和0到9几个阿拉伯数字放到汉字库中。要在液晶屏上显示时再用LCD_Paint_Hz（）函数调用字库输出。 程序太长了，贴出来也不方便。等毕业了再全部上传。把主要函数说下吧。LCD_Paint_Hz(70,140,16,1,&hz16,0xffff,0x0000);这句中70和140是输出的字在屏幕上的位置，16和1我也没仔细看懂是啥作用，我一般默认这两个参数。hz16[]这个数组保存着字库中所有字取模后的数据（一般每个字为32个数据）。0xffff,0x0000为输出字的颜色和背景颜色。字库见附件。我上面这句函数输出的就是“第”字。有兴趣的可以试试。修改hz16中的224可以输出字库中其他字，如将224改为256，输出的就是“一”字。当然这些仅仅是基本的字库输出演示。晕了，不支持上传.C文件。汉字字库的代码贴下面吧。顺便说下，我的屏是东华3.5寸液晶屏。
#include "LCD_TFT.h"
#define WIN32
#if(LCD_Type == LCDW35) // 3.5寸屏
unsigned char hz16[] = {
