Arduino+W5100 通过LeweiClient上传数据，不用再理解http了-乐联网应用
本帖最后由 laoliu1982 于 2013-3-3 10:15 编辑之前用W5100，参考cosm client的程序，上传，感觉对于不了解http的爱好者用起来不是很友好，比如计算content-length的时候，不容易描述清楚，最近把http post的过程封装成了LeweiClient 类库，去掉了类似content-length 的计算过程，终于让数据上传乐联网不用再了解http 的相关细节了。

代码已经更新到 https://github.com/lewei50/leweiclient可能与这里的不一致，以github上面为准
需要把 LeweiClient 两个文件(leweiclient.c leweiclient.h )放到 librariesLeWei 里并且在 IDE 里引用，USER_KEY需要修改

lwc = new LeWeiClient(LW_USERKEY, LW_GATEWAY);
}
void loop() {
// read the analog sensor:
//int sensorReading = analogRead(A0);
// if there's incoming data from the net connection.
// send it out the serial port.This is for debugging
// purposes only:
if (lwc) {
Serial.print("*** start data collection ");
lwc->append("BH", 123);
lwc->append("DS1", 456);
Serial.print("*** start either net send ");
lwc->send();
Serial.print("*** stop either net send ");
delay(POST_INTERVAL);
}
}

辛苦了，顺求有空做个28j60版的
这两天就发一个28J60的 编译报错
