大橙子网站建设,新征程启航
为企业提供网站建设、域名注册、服务器等服务
将micro:bit连接到电脑。
创新互联是一家集网站建设,高密企业网站建设,高密品牌网站建设,网站定制,高密网站建设报价,网络营销,网络优化,高密网站推广为一体的创新建站企业,帮助传统企业提升企业形象加强企业竞争力。可充分满足这一群体相比中小企业更为丰富、高端、多元的互联网需求。同时我们时刻保持专业、时尚、前沿,时刻以成就客户成长自我,坚持不断学习、思考、沉淀、净化自己,让我们为更多的企业打造出实用型网站。
第一步:将micro:bit连接到电脑,使用microUSB数据线将micro:bit与电脑连接。你的micro:bit会在“我的电脑”上以“MICROBIT”的名称显示出来,不过要注意,它并不是一个普通的U盘哦。
第二步:在电脑上给它编程,你可以用MakeCode编辑器,或者Python为micro:bit进行编程。MakeCode编辑器采用的是拖放积木式的图形化编程,内核语言是JavaScript。在这个例子中,能够让micro:bit上显示闪烁的心形图案。Python编辑器允许用户使用目前流行的Python语言进行编程。试试这个例子,同样能够让micro:bit上显示闪烁的心形图案哦。
第三步:把程序下载到电脑上点击编辑器中的Download(下载)按钮。一个名为“hex”类型的文件会下载到你的电脑里,这是一种专门供micro:bit读取的小体积文件。一旦完成hex文件下载,你可以把它拷贝到micro:bit上,就像拷贝一个普通文件到U盘上一样。在Windows系统中,你也可以右键单击hex文件,选择“发送到→MICROBIT”。
第四步:玩起来当micro:bit在读取程序时会暂停运行,同时后面的黄色LED开始闪烁。一旦完成读取,程序会自动开始运行。

/**

function convertImgToBase64(url, callback, outputFormat){
var canvas = document.createElement('CANVAS'),
ctx = canvas.getContext('2d'),
img = new Image;
img.crossOrigin = 'Anonymous';
img.onload = function(){
var dataURL;
canvas.height = img.height;
canvas.width = img.width;
ctx.drawImage(img, 0, 0);

};
img.src = url;
}
