各位大神，求助enc28j60
之前用enc28j60+arduino+yeelink做了个小系统，现在想让pc和arduino通信，怎么也调不通啊，我原来是用的if (ether.begin(sizeof Ethernet::buffer, mymac) == 0)
Serial.println( "Failed to access Ethernet");
Serial.println("Setting up DHCP");
if (!ether.dhcpSetup())
Serial.println( "DHCP failed");
ether.printIp("My IP: ", ether.myip);
ether.printIp("Netmask: ", ether.mymask);
ether.printIp("GW IP: ", ether.gwip);
ether.printIp("DNS IP: ", ether.dnsip);
这个局域网里可以ping通，外网也可以ping通，现在想调局域网内的通讯却怎么也搞不通，用的是
Ethernet.begin(mac, ip);
加上网关和掩码也不行，局域网内ping都ping不通，搞不明白啊，是库用的不对还是怎么回事
ide 1.01，求大神指导 还有另外一个库，程序是
#include <EtherCard.h>
// ethernet interface mac address, must be unique on the LAN
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x31 };
static byte myip[] = { 172,20,10,203 };
char website[] PROGMEM = "api.yeelink.net";
byte Ethernet::buffer;
static BufferFiller bfill;// used as cursor while filling the buffer
void setup () {
Serial.begin(9600);
if (ether.begin(sizeof Ethernet::buffer, mymac) == 0)
Serial.println( "Failed to access Ethernet controller");
Serial.println("Setting up DHCP");
if (!ether.dhcpSetup())
Serial.println( "DHCP failed");
ether.printIp("My IP: ", ether.myip);
ether.printIp("Netmask: ", ether.mymask);
ether.printIp("GW IP: ", ether.gwip);
ether.printIp("DNS IP: ", ether.dnsip);
if (!ether.dnsLookup(website))
Serial.println("DNS failed");
ether.printIp("Server: ", ether.hisip);
Ethernet.begin(mac,ether.myip);
server.begin();
}
static word homePage() {
long t = millis() / 1000;
word h = t / 3600;
byte m = (t / 60) % 60;
byte s = t % 60;
bfill = ether.tcpOffset();
bfill.emit_p(PSTR(
"HTTP/1.0 200 OK\r\n"
"Content-Type: text/html\r\n"
"Pragma: no-cache\r\n"
"\r\n"
"<meta http-equiv='refresh' content='1'/>"
"<title>RBBB server</title>"
"<h1>$D$D:$D$D:$D$D</h1>"),
h/10, h%10, m/10, m%10, s/10, s%10);
return bfill.position();
}
void loop () {
word len = ether.packetReceive();
word pos = ether.packetLoop(len);
Serial.println(len);
Serial.println(pos);
if (pos)// check if valid tcp data is received
{
bfill = ether.tcpOffset();
Serial.println("data=");
char* data = (char *) Ethernet::buffer + pos;
// Serial.println(data,DEC);
ether.tcpSend();
delay(200);
}
//ether.httpServerReply(homePage()); // send web page data
}
这个可以ping通，但是数据发不过去，有可能是没弄懂怎么显示，发过去的应该是字符串，不知道怎么转换，搞不懂啊，求大神指点
示例里的 server 应以啊
qq 365815350 应该能帮到你
