ESP32S3通过W5500以太网模块发送数据，并进行简单测速实验。
utilities.h文件中的需要打开17行的注释：LILYGO_T_ETH_LITE_ESP32S3。需要跟你你自己的主机的ip地址修改程序。硬件：ESP32S3和W5500。我这里使用jperf进行简单测速。目录下的TCPClient程序。打开TCP Server。
·
硬件：ESP32S3和W5500
连线按照上述的硬件连接
程序:参考的GitHub - Xinyuan-LilyGO/LilyGO-T-ETH-Series目录下的TCPClient程序
utilities.h文件中的需要打开17行的注释：LILYGO_T_ETH_LITE_ESP32S3
