<h3>1、团队介绍</h3>
<p>大家好我是来自济南的一名电子爱好者。前几届立创电子设计大赛都有看过一些项目,有些做的确实不错,从中也学到了不少东西,但是作为受到开源项目受益的人也不能一直白嫖😊,还是应该有所奉献,业余时间也想做一些有趣的小东西,况且嘉立创的5元PCB打样是真香,也确实方便。最后希望给大赛增加些人气,也顺便拉低一下获奖率😄。</p>
<h3>2、简要介绍项目</h3>
<p>夏天到了,很多小盆友尤其是学生党应该会买一些USB风扇吧,这些USB风扇往往会带有两档调节包括高低档,而且调节还不方便,一些稍微高档一点的风扇往往会带有多个挡位,但是价格往往就比较美丽了,作为一名电子爱好者,我们会花那些冤枉钱,不可能的的哈哈。
没错,以上就是我想要做这个产品的初衷,当然它的功能还不只如此,它还支持恒压、恒流(酷毙灯调光)、红外遥控(方便调节)等等功能,具体描述见下方项目描述详情。</p>
<h3>1、描述项目详情</h3>
<ul>
<li>开机USB滚动动画。</li>
<li>低硬件成本,采用STM8S003单片机,单价一元左右,整体硬件成本约6元</li>
<li>5V USB供电,可用充电宝供电,支持3.0V - 12V直流输出。</li>
<li>PID调节,支持恒压、恒流模式。</li>
<li>软件缓启动、过流、过压保护。</li>
<li>当前室内温度显示。</li>
<li>采用3位数码管可显示实时电流、实时电压、实时温度等。</li>
<li>配置断电保存功能。</li>
<li>支持在机身的轻触按键及红外遥控配置电压电流等参数。</li>
<li>支持遥控关机和单独关闭屏幕功能。</li>
</ul>
<h3>2、描述项目所面临的挑战及所解决的问题</h3>
<h5>问题:</h5>
<ul>
<li>STM8引脚的数量不是很多</li>
<li>MOS管的快速关断</li>
<li>STM8主频不是很高,pwm的频率低</li>
<li>遥控器长按按键的支持</li>
<li>数码管进入菜单,单独菜单功能码闪烁的实现</li>
</ul>
<h5>解决:</h5>
<ul>
<li>充分利用单片机管脚,使用74HC595驱动数码管,减少引脚使用</li>
<li>改进MOS驱动电路,工作原理详见➡<a href="https://blog.csdn.net/qq_25848569/article/details/107807090" target="_blank">链接</a></li>
<li>通过增加电感值,弥补PWM工作频率低的问题</li>
<li>通过定时器中断,解析脉冲的时间长度实现遥控器长按的支持</li>
<li>通过对指定位的跳过位选开启实现单独功能码的闪烁功能</li>
</ul>
<h3>3、描述项目硬件、软件部分涉及到的关键点</h3>
<ul>
<li>中断方式红外码采集,按键长按支持</li>
<li>面向对象化显示菜单处理</li>
<li>PID调节,恒流恒压模式</li>
</ul>
