【向金老师原创】掌控来贺：“国庆快乐”
本帖最后由 rzyzzxw 于 2018-10-3 00:13 编辑掌控来贺“国庆快乐”向金掌控收到已经好几天了，但是由于忙于“世界人工智能大会”的分享事情，所以耽误好久没有动手做点东西。借着国庆，想看看能做点什么，看了官方的介绍后，想试试中文显示。结果第一次真的失败了：原因很简单，把PEPL交互模式和刷入下载模式开始搞混了。好了，闲话少说，我们不如正题，首先看看视频效果：http://v.youku.com/v_show/id_XMzg0NTM2NTgwNA==.html?spm=a2h3j.8428770.3416059.1制作过程：一、 处理图片：1、 随便网上搜索“国徽”、“天安门”然后下载到本地。2、 将图片处理成45*45（国徽）、81*48（天安门）分辨率的图片，这个有很多工具，但是我的电脑上没有安装任何图片处理的软件，所以就在用了一个在线的图片处理平台：改图宝http://www.gaitubao.com/（为什么使用这个像素：那是因为掌控屏幕的分辨率是128*64，考虑到第一行显示中文，占用了128*16的分辨率，所以只剩下128*48） 3、 利用取模工具对图片进行取模。网上有PCtoLCD、lcd image converter等取模软件，可根据自己喜好自行选择。以下使用的是Img2Lcd工具。l 步骤1.导入刚才修改后的图片 l 步骤2.选择参数,输出数据类型、 扫描模式[水平扫描]、输出灰度[单色]、宽高（注意：一定要根据实际图片效果来调整亮度和对比度，已达到最佳显示效果）l 步骤3.保存数据：点击保存，填写好文件名，自动会弹出图像的取模值。但是我们在使用的时候一定要注意：前面的注释部分（下图中的蓝色部分）不能写入一会儿的程序中。二、 做好上面的工作后就可以开始编写程序，对于新手来说，可以逐步来编写。1、第一个程序：显示“国庆快乐！”程序如下：from mpython import * #导入库文件display.DispChar('国庆快乐！', 38, 0) #显示字符串（可以是中、英、日、韩文），后面两个参数代表显示的起始数列和横列的像素点的坐标display.show() #执行显示命令小编注：小白一定要注意正确的下载和运行方法：首先：点击连上掌控板后，利用mPython软件编写好程序后点击上面的“刷入”按钮，如下图：等待掌控板三次蜂鸣后在软件的下方会出现如下两个方框。其次：选择刚才下载到掌控板的那个文件名，单机右键，选择运行，等待掌控板一次蜂鸣后开始运行程序。如下图：2、第二个程序：显示“国庆快乐！”加国徽：程序如下：程序分为这几个部分第一部分：调用库文件第二部分：设置图片的数组，该部分数组来自图像取模工具，就是刚才我们生成的那个c文件，第三部分：创建缓存，读取图片第四部分：主程序部分完整代码如下：from mpython import *

display.blit(fb1,38,16)#将fb1帧缓存送至oled显示，起始位(38,16)
display.show() 3、第三个程序：制作一个交替显示的动画。其实这不是动画，而是两个“文字+图像”交替显示，程序如下：这里和上一个程序最大的区别如下：（1）、多了一个图像的数组，所以第二个数组命名时我使用了bmp2（当然您可以自己命名，但不能有重名）；（2）、缓存区也有对应的有两个，所以命名也不能重名；（3）、增加了循环、延时、清屏三个命令（见注释）。完整的程序代码如下：from mpython import *
