1、如果要使用NDK,那你所建立的ccs工程必须是跑sys/bios的工程。
2、如果想看6678的网络demo,那么其demo路径为:C:\ti\mcsdk_2_01_02_06\examples\ndk\helloWorld
3、DSP的本地IP主要在helloworld.c中的以下代码段设置
char *HostName = "tidsp";
char *LocalIPAddr = "192.168.2.100";
char *LocalIPMask = "255.255.255.0"; // Not used when using DHCP
char *GatewayIP = "192.168.2.101"; // Not used when using DHCP
char *DomainName = "demo.net"; // Not used when using DHCP
char *DNSServer = "0.0.0.0"; // Used when set to anything but zero
4、设置DHCP还是静态IP,主要体现在helloworld.c中的以下代码段:
// If the IP address is specified, manually configure IP and Gateway
#if defined(_SCBP6618X_) || defined(_EVMTCI6614_) || defined(DEVICE_K2H) || defined(DEVICE_K2K)
/* SCBP6618x, EVMTCI6614, EVMK2H, EVMK2K always uses DHCP */
if (0)
#else
if (!platform_get_switch_state(1))
#endif
{
CI_IPNET NA;
CI_ROUTE RT;
IPN IPTmp;
// Setup manual IP address
bzero( &NA, sizeof(NA) );
NA.IPAddr = inet_addr(LocalIPAddr);
NA.IPMask = inet_addr(LocalIPMask);
strcpy( NA.Domain, DomainName );
NA.NetType = 0;
// Add the address to interface 1
CfgAddEntry( hCfg, CFGTAG_IPNET, 1, 0,
sizeof(CI_IPNET), (UINT8 *)&NA, 0 );
// Add the default gateway. Since it is the default, the
// destination address and mask are both zero (we go ahead
// and show the assignment for clarity).
bzero( &RT, sizeof(RT) );
RT.IPDestAddr = 0;
RT.IPDestMask = 0;
RT.IPGateAddr = inet_addr(GatewayIP);
// Add the route
CfgAddEntry( hCfg, CFGTAG_ROUTE, 0, 0,
sizeof(CI_ROUTE), (UINT8 *)&RT, 0 );
// Manually add the DNS server when specified
IPTmp = inet_addr(DNSServer);
if( IPTmp )
CfgAddEntry( hCfg, CFGTAG_SYSINFO, CFGITEM_DHCP_DOMAINNAMESERVER,
0, sizeof(IPTmp), (UINT8 *)&IPTmp, 0 );
}
// Else we specify DHCP
else
{
CI_SERVICE_DHCPC dhcpc;
// Specify DHCP Service on IF-1
bzero( &dhcpc, sizeof(dhcpc) );
dhcpc.cisargs.Mode = CIS_FLG_IFIDXVALID;
dhcpc.cisargs.IfIdx = 1;
dhcpc.cisargs.pCbSrv = &ServiceReport;
CfgAddEntry( hCfg, CFGTAG_SERVICE, CFGITEM_SERVICE_DHCPCLIENT, 0,
sizeof(dhcpc), (UINT8 *)&dhcpc, 0 );
}
其中switch_state是拨码开关,有的开发板上直接是固定的,官方板上该开关可以拨动。
5、可以在以下代码段创建socket进程,用来传输数据:
static void NetworkOpen()
{
// Create our local server
// 下面这个函数的第三个参数是接收进程的端口设定
// hHello = DaemonNew( SOCK_DGRAM, 0, 7, dtask_udp_hello,
// OS_TASKPRINORM, OS_TASKSTKNORM, 0, 1 );
hSend = TaskCreate ( dtask_udp_hello, "UDP_Send", OS_TASKPRIHIGH,
OS_TASKSTKNORM, 0, 0, 0 );
hSend = TaskCreate ( task_sendto_PC, "UDP_Send", OS_TASKPRINORM,
OS_TASKSTKNORM, 0, 0, 0 );
// 当然也可以创建接收进程啦
}
注意:必须在发送/接收进程执行任务完成之后执行fdCloseSession(TaskSelf());否则影响堆栈分配
6、至于task_sendto_PC怎么写,那就是socket编程的事情啦!
