构建追星仪（二）---控制步进电机

耗时：3小时

成果：步进电机初步可控

======================================================

终于空出来了一个下午，开始搭建步进电机

开关电源，连线了HBS57驱动器，电机和控制器做了连线，其实这些都还好，只花了我1个小时左右，是卡在了没有合适的螺丝刀上，后来下楼买了合适的螺丝刀之后，就算OK了；

Arduino开发板在公司，懒得去拿了，然后就用ruff来连接了hbs57驱动器；

电机与驱动器的连接方式，在电机上有写，按照颜色一个个细心接好就行了；

然后，是ruff那边

关键是ruff和hbs57的接线方式，一开始让我迷惑了很久

后来才看懂那张图。实际上最终我用的是共阳极接法

我把PWM的输入给了PUL-，然后VDD信号给了PUL+，OK，就转起来了；

接下来，应该是要看一下：

这个库了，另外用Arduino来控制；

1、安装驱动并且添加设备

C:\Users\lemon\Desktop\ruff-sdk-win-1.11.12\hello>..\bin\rap install servo-mg996r-driver

Downloading package "servo-mg996r-driver"...

Extracting package "servo-mg996r-driver" (0.1.5)...

2、查看连接图

C:\Users\lemon\Desktop\ruff-sdk-win-1.11.12\hello>..\bin\rap layout --visual

3、修改代码到：

'use strict';

$.ready(function (error) {

if (error) {

console.log(error);

return;

}

$('#led-r').turnOn();

$('#hbs57').setAngle(50);

});

$.end(function () {

$('#led-r').turnOff();

});
