【AT-START-F407测评】+ 网口试验
本帖最后由 比神乐 于 2021-1-31 13:50 编辑今天捣鼓了一下网口试验。
TCP客户端。
代码：

/* Initilaize LwIP satck, IP configuration and MAC configuration*/
LwIP_Init();
/* Initialize TCP client module */
TCP_Client_Init(TCP_LOCAL_PORT,TCP_SERVER_PORT,TCP_SERVER_IP);//Initialize TCP client
while(1)
{
pcb = Check_TCP_Connect();
if(pcb != 0)
{
TCP_Client_Send_Data(pcb,tcp_data,sizeof(tcp_data)); //Send data to TCP server actively
}
Delay_s(0xfffff); //necessary delay
System_Periodic_Handle(); //Update TCP timers
}
}
/**

*/
void Delay(uint32_t nCount)
{
/* Capture the current local time */
timingdelay = LocalTime + nCount;
/* wait until the desired delay finish */
while(timingdelay > LocalTime)
{
}
}
/**

}/* TCP server and client configuration*/
#define TCP_LOCAL_PORT 1030
#define TCP_SERVER_PORT 1031

static uint8_t G_GW = {192, 168, 1, 187};
static uint8_t G_MASK = {255, 255, 255, 0};效果图：
注意还要关闭防火墙。
厉害 小辣椒哥哥~ 能分享代码吗 无所谓随意 发表于 2021-2-2 15:10
能分享代码吗
例程一点都没改 有空可以试试IPERF例程，测试一下看看网速多少。 可以分享一下代码吗？
