对Follow me4项目的过往进行总结
因为是第一次应用树莓派的RP2040，很多地方比较生疏，所以选择了最为官方推荐的方案 W5500-EVB-Pico、 Adafruit Sharp Memory Display，跟在大家的后面，一起学习进步。
这次收获满满，认识了RP2040，了解了micro python和circuit python编程的方便，更是学到了许多TCP/IP相关的知识，收益颇丰！
汇总视频：
一、入门任务：
1、开发环境搭建，这里选择了micro python和circuit python进行后续工作，刷写固件也很方便
2、LED灯BLINK闪闪，驱动液晶显示器进行显示

while True:
# 点亮LED
led.on()
time.sleep(1) # 等待1秒钟
# 熄灭LED
led.off()
time.sleep(1) # 等待1秒钟
3、驱动sharp的lcd屏幕，显示信息

二、基础任务一
完成主控板W5500初始化(静态IP配置)，并能使用局域网电脑ping通，同时W5500可以ping通互联网站点；通过抓包软件(Wireshark、Sniffer等)抓取ping报文析。

整个Follow me第四期下来，收获满满，自己作为小白，首先把pico裸机的外设端口学习了一遍，接着摸索着点亮了sharp的LCD屏幕，显示的那一瞬满是开心，也许电子这一行的快乐可能就是调通的那一刹那，后面在TCP/IP这块，配合着WiFi那块板子的调试进度，对client和servers有了更进一步的认知，在这块是真的学到了些许东西；最后的FTP服务器，自己没搞定，学习了论坛其他小伙伴的程序，后续随着自己的学习不断完善；
最后，谢谢得捷和EEworld的组织的这次活动，和给予的这次参与机会，组织的很棒。以后我会多加关注，积极参加论坛活动，多方面提升个人的知识，与大家一同进步，加油！
