LGT8F328P 开发板arduino环境搭建：
1. 在官网上下载 Arduino硬件支持包
http://www.lgtic.com/downloads/
Arduino开发平台相关
解压，把压缩包中..\Larduino_HSP_latest\Larduino_HSP_v3.6c\hardware\ 目录下的LGT 目录复制到 Arduino hardware "D:\Program Files (x86)\Arduino\hardware\" 目录下。
2. 参考如下博客，把芯片和下载器连接好
https://blog.csdn.net/XIUYING_MO/article/details/103942255
3. 打开Arduino，选择开发板
4. 编程
