前言
结合正点原子以及野火的基础例程，理解了VGA本身基本协议，VGA本身显示像素为640*480，因此注意生成文字或者数字的字模不要太大。本文以VGA显示文字“心率测试”，以及数字“68”
本文不再对VGA驱动的编写作过多叙述，而是在例程的基础上进行修改。
一、VGA显示参数
显示方式从左到右，从上到下。
显示模式：640x480@60
640x480是指VGA的分辨率，640是指有效显示图像每一行有640个像素点，480是指每一帧图像有480行，640 * 480 = 307200 ≈ 300000，每一帧图片包含约30万个像素点，之前某品牌手机广告上所说的30万像素指的就是这个；@60是指VGA显示图像的刷新频率，60就是指VGA显示器每秒刷新图像60次，即每秒钟需要显示60帧图像。
时钟(MHz)：25.175MHz
这是VGA显示的工作时钟，像素点扫描频率。
具体的时钟计算流程野火教程中有讲解。
二、字模生成
如果要显示文字或者数字，前提是要生成字模，通过字模软件把字模导出来。关键在于控制字模数组的长宽。
比如：生成“你”这个字的字模，选用的想字体点阵大小是6464
所以关键在于控制输出字模数组的宽度和深度。因为这个你字我们设置的是6464的，所以输出的数组也要是64*64的。
如何进行修改呢，**主要是改这个每行显示数据这，**点阵数决定了你每行的输出。
输出正确的数组格式为：
因为输出的是16进制，所以横向看起来很窄，换成2进制的话就是64位了。
但是如果你设置不对，输出的数组就不是6464的，到时候显示就会有问题。
错误案例：
显示数据也是同样的道理，但是注意，即使你设置数字的点阵大小也是6464，但是实际数字的点阵大小只需要32*64，英文字母跟数字都只需要文字的一半宽度。因此生成数组要注意，单个字母和数字只需要输出32*64即可。
比如显示数字1
这样生成的数组就是32*64了：
生成完字模之后，就需要把字模数据放到代码里面的数组进行扫描读取即可。
三、代码分析

乱码，建议去下载野火科技的VGA例程，然后对应修改pic部分即可。

3.vga_pic数据准备文件
我是用来显示心率数据的，所以我设置的是4个文字，所以长是64*4=256 宽是64
后面数字显示3位，我是一位一位的显示，每一次显示都是32*64的
如果你只想验证显示固定数字，只需要把HEART_data_h和 HEART_data_l赋值为固定数字即可。
最后注意工作时钟50Mhz，VGA工作时钟25MHz,用一个锁相环ip核产生一下就行。
