Arduino udp ping

---

首先，为了解释我的目标，我试图用UDP（用户数据报协议）协议控制我的机器人前进、后退、向右、向左和停止

• 我正在使用
  • Arduino Mini Atmega168
  • 兰ENC28J60
  • 路由器Tp-Link 150Mbps无线N Nano
  • 电机驱动器L293D

• 和C#中的应用程序，带有向前、向后、向左、向右和停止按钮

  arduino的ip地址是192.168.178.60我正在ping该地址，没有问题，但如果我试图更快地点击按钮进行控制，或者点击任何按钮并留出更多时间。例如，前进阻止或向左阻止，我必须重新启动arduino才能恢复ping。主要的问题是为什么我这么快就断了连接。

这是我的代码

#include "EtherShield.h"
//8 or 16 bit integer
uint8_t mymac[6] = {0xCF,0x70,0x7C,0xE4,0x8A,0xB8};
uint8_t myip[4] = {192,168,178,60};
uint16_t MYWWWPORT = 80; 
#define BUFFER_SIZE 750
static uint8_t buf[BUFFER_SIZE+1];
EtherShield es=EtherShield();
uint16_t dat_p;
