<div class='showpostmsg'><p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif"><span style="font-family:宋体">首先感谢</span>EE<span style="font-family:宋体">的这次树莓派</span>Pico<span style="font-family:宋体">测评活动,这次活动我学习了很多</span>Pico<span style="font-family:宋体">的硬件和相关软件的知识。下面对</span>Pico<span style="font-family:宋体">学习内容,优点,缺点三大类和大家汇报一下测评心得。</span></span></span></p>

<p style="text-align:justify">&nbsp;</p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif"><span style="font-size:16.0pt"><span style="font-family:宋体">一,学习内容</span></span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">1<span style="font-family:宋体">,学习了</span>Pico<span style="font-family:宋体">的硬件电路设计的一些思想,主要分析了</span>DC/DC<span style="font-family:宋体">电路。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">2<span style="font-family:宋体">,学习</span>Pico<span style="font-family:宋体">的最小电路,调试程序的方法,和相关的软件安装。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">3<span style="font-family:宋体">,学习了</span>Pico<span style="font-family:宋体">的基本外设(</span>IO,PWM,<span style="font-family:宋体">等)的使用方法。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">4<span style="font-family:宋体">,学习了一些常用外设的驱动方法(</span>LCD1602,DS18B20,FAN<span style="font-family:宋体">等)。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">5<span style="font-family:宋体">,学习了</span>MicroPython<span style="font-family:宋体">的基本语句和编程方法,我是一名硬件工程师,平时会一点</span>C<span style="font-family:宋体">编程,这次学习</span>MicroPython<span style="font-family:宋体">感觉没有</span>C<span style="font-family:宋体">严谨和有效率,在对时间控制比较严格的情况下感觉还是使用</span>C<span style="font-family:宋体">比较方便。</span></span></span></p>

<p style="text-align:justify">&nbsp;</p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif"><span style="font-size:16.0pt"><span style="font-family:宋体">二,</span></span><span lang="EN-US" style="font-size:16.0pt">Pico</span><span style="font-size:16.0pt"><span style="font-family:宋体">的优点</span></span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">1<span style="font-family:宋体">,信仰芯片,树莓派在微型电脑方面获得巨大成功,推出</span>Pico<span style="font-family:宋体">自然也有大批的跟随者使用。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">2<span style="font-family:宋体">,生态方面,</span>Pico<span style="font-family:宋体">支持</span>MPY<span style="font-family:宋体">和</span>C<span style="font-family:宋体">,相信以后会有越来越多的资料。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">3<span style="font-family:宋体">,硬件方面,树莓派有</span>8<span style="font-family:宋体">个可编程</span> I/O<span style="font-family:宋体">(</span>PIO<span style="font-family:宋体">)状态机,用于自定义外围设备支持。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">4<span style="font-family:宋体">,质量方面,树莓派芯片的质量由于是大厂出品,质量有保证。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">5<span style="font-family:宋体">,程序下载方便,直接</span>USB<span style="font-family:宋体">连接,程序拖拽就可以了。免了调试器。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">6<span style="font-family:宋体">,</span>PCB<span style="font-family:宋体">板兼容</span>DIP40<span style="font-family:宋体">,方便测试。</span></span></span></p>

<p style="text-align:justify">&nbsp;</p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif"><span style="font-size:16.0pt"><span style="font-family:宋体">三,</span></span><span lang="EN-US" style="font-size:16.0pt">Pico</span><span style="font-size:16.0pt"><span style="font-family:宋体">的缺点</span></span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">1<span style="font-family:宋体">,价格还是贵了点,价格</span>30<span style="font-family:宋体">元,而同样国内的</span>ESP32<span style="font-family:宋体">模块才</span>10<span style="font-family:宋体">多元的价格,所以价格是硬伤。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">2<span style="font-family:宋体">,刚推出的芯片,资料相对</span>ESP32<span style="font-family:宋体">要少,有一些技术问题无法借鉴。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">3<span style="font-family:宋体">,硬件方面,</span>Pico<span style="font-family:宋体">的</span>IO<span style="font-family:宋体">是</span>3.3V<span style="font-family:宋体">输出,不兼容</span>5V<span style="font-family:宋体">,而且没有保护,有一些外设互联还是有电平匹配的问题。</span>IO<span style="font-family:宋体">接错了容易烧。</span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:Calibri,sans-serif">4<span style="font-family:宋体">,没有无线功能。</span></span></span></p>

<p style="text-align:justify">&nbsp;</p>

再搞点什么事情玩呗。

<p>玩别的得看合适的机会和项目,低端的MCU做,高端点的树莓派做,Pico我感觉正好是处于它俩的中间。要是有要求CPU速度快,RAM大。PWM通道多的可以考虑用它。</p>
