首先是最后实现的效果
所需要的器材：
一块8*8的ws2812点阵
一块arduino uno
杜邦线若干
所需要的软件
取模软件
arduino ide或者mixly
开始！
首先我们需要确定我们WS2812点阵的方向，这个要和之后的取模软件的设置一致
在这里，我的WS2812点阵的方向如下
所以，我就以我的点阵的方向为例
在确定了点阵的方向之后，我们打开取模软件
将软件设置和下图一样
接着我们新建一幅8*8的图像
然后点击图中的点阵，画出自己想要的图案，左击是画上，右击是删除
如果在后面显示的时候发现显示的图像是左右反转的，可以点一下程序中的这个按键
画好图案之后点击下方的生成字模
得到以下字符
未命名文件(0)
0xFF,0x10,0x10,0xFF,0x10,0x28,0x44,0x82;"未命名文件",0
/* (8 X 8 )*/然后打开电脑自带的计算器，设置为程序员模式
选中16进制，然后连续输入刚刚获得的16进制数
便得到64个2进制数
1111111100010000000100001111111100010000001010000100010010000010接着我们需要将这一段数字每隔一个加一个分号，改成如下格式
1,1,1,1,1,1,1,1,0,0,0,1,0,0,0,0,0,0,0,1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,1,0,0,0,0,0,0,1,0,1,0,0,0,0,1,0,0,0,1,0,0,1,0,0,0,0,0,1,0
那么如何将那一串数字改成如下格式呢，二个办法，一个是手动加，不过这样很麻烦，所以我用的是第二种，借助EXCEL表格来完成。
首先我们打开EXCEL
在A1单元格粘贴刚刚那一串2进制
接着右键A1单元格，设置单元格格式
设置单元格格式为文本
接着在B1单元格中粘贴以下代码
=LEFT(A1,1)&","&MID(A1,2,1)&","&MID(A1,3,1)&","&MID(A1,4,1)&","&MID(A1,5,1)&","&MID(A1,6,1)&","&MID(A1,7,1)&","&MID(A1,8,1)&","&MID(A1,9,1)&","&MID(A1,10,1)&","&MID(A1,11,1)&","&MID(A1,12,1)&","&MID(A1,13,1)&","&MID(A1,14,1)&","&MID(A1,15,1)&","&MID(A1,16,1)&","&MID(A1,17,1)&","&MID(A1,18,1)&","&MID(A1,19,1)&","&MID(A1,20,1)&","&MID(A1,21,1)&","&MID(A1,22,1)&","&MID(A1,23,1)&","&MID(A1,24,1)&","&MID(A1,25,1)&","&MID(A1,26,1)&","&MID(A1,27,1)&","&MID(A1,28,1)&","&MID(A1,29,1)&","&MID(A1,30,1)&","&MID(A1,31,1)&","&MID(A1,32,1)&","&MID(A1,33,1)&","&MID(A1,34,1)&","&MID(A1,35,1)&","&MID(A1,36,1)&","&MID(A1,37,1)&","&MID(A1,38,1)&","&MID(A1,39,1)&","&MID(A1,40,1)&","&MID(A1,41,1)&","&MID(A1,42,1)&","&MID(A1,43,1)&","&MID(A1,44,1)&","&MID(A1,45,1)&","&MID(A1,46,1)&","&MID(A1,47,1)&","&MID(A1,48,1)&","&MID(A1,49,1)&","&MID(A1,50,1)&","&MID(A1,51,1)&","&MID(A1,52,1)&","&MID(A1,53,1)&","&MID(A1,54,1)&","&MID(A1,55,1)&","&MID(A1,56,1)&","&MID(A1,57,1)&","&MID(A1,58,1)&","&MID(A1,59,1)&","&MID(A1,60,1)&","&MID(A1,61,1)&","&MID(A1,62,1)&","&MID(A1,63,1)&","&MID(A1,64,1)
设置好了之后点回车
就可以看到B1中的内容变成了
然后复制B1的内容右键，粘贴值到B2
然后B2中就是我们要的数据了，为了保证数据的长度没有问题，我们在B3中输入以下代码
=LEN(B2) 可以看到B2那串数据的长度为127，这个长度是正常的
最后我们将B2的那串字符复制到程序中
接线为
arduino WS2812
vcc vcc
gnd gnd
d2 vin
mixly程序
把B2那串字符串复制到以下位置
arduino代码，复制到xxx数组就行
#include <Adafruit_NeoPixel.h>
Adafruit_NeoPixel rgb_display_2 = Adafruit_NeoPixel(64,2,NEO_GRB + NEO_KHZ800);
int XXX[64]={1,1,1,1,1,1,1,1,0,0,0,1,0,0,0,0,0,0,0,1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,1,0,0,0,0,0,0,1,0,1,0,0,0,0,1,0,0,0,1,0,0,1,0,0,0,0,0,1,0};
void setup(){
rgb_display_2.begin();
}
void loop(){
rgb_display_2.setBrightness(20);
for (int i = 0; i <= 63; i = i + (1)) {
if (XXX[(int)((i - 0) - 1)] == 1) {
rgb_display_2.setPixelColor((i)-1, 125*65536+125*256+0);
} else {
rgb_display_2.setPixelColor((i)-1, 0*65536+0*256+0);
}
}
rgb_display_2.show();
}然后上传程序，就可以看到效果了
