硬件类问题
1.1 初学者购买屏后如何快速入门
在有串口屏之后，首先在网上 “资料下载”栏中，下载《串口屏开发包》，如图 1.1
所示，开发包里面包含了PC 软件、软件视频教程、数据手册、常用问题解答和程序例程等。
我们只需根据开发包里面的学习步骤，一步步体验，认真阅读例程代码，即可迅速掌握开发。

1.2 如何查看固件版本号
固件版本号代表了设备烧入的程序版本。我们在使用串口屏时候，若遇到了一些难以解
决的问题，建议将问题描述和设备版本信息一起发送给技术支持。获取版本的方法如下：
1. 直接看屏背面标签。正常情况下，产品出厂前背面均有型号和标签，我们只需将产
型号和版本标签告诉即可，如图 1.2 所示。
