[ESP8266/ESP32] firebeetle2 esp-c6试用报告2——小白又来了

经历环境配置之后，用Arduino IDE点灯后，对于初学者小白来说是鼓舞，但是也是没有任何技术含量的项目，但是没关系，大佬们不都是从不会到会的过程么？

于是，我的第二篇试用报告来了，还是基础的入门，通过firebeetle2 esp-c6点亮led屏。
作为学渣文具多的典型，我有好几套的arduino的实验套餐，道具虽多，但是技术有限，勉强完成了点屏。
首先打开arduino IDE，选择板子类型跟端口，连接设备。一开始，想一口吃个胖子，使用温湿度传感器在屏幕上显示温湿度，结果失败了，粗浅的找下原因，一是温湿度的传感器不匹配库，二是板子的插针我没焊，解除不良。

后来，放弃了这艰巨的任务，留着后面慢慢再探索吧。于是我把温湿度传感器拆了，留下来屏幕，找到相关的点led程序。

在整个过程中，遇到了几点问题：
一是插针接触不良，led没有亮，我以为是型号问题，换了一个led屏。
二是GDL库版本要安装。

三是整个程序跑完没问题，但是屏幕没反应，提示'hard resetting',手动按了板子上的reset键，再重新烧录程序就可以了
