之前想外包的东西，正好最近有时间，就和兼职人员一起搞定了，自动亲自动手做了，才知道也没什么难的：

BCM43362的芯片没任何资料，不过可以去broadcom注册一下，下载他们的WICED
他们没有提供STM32F1的支持，而且，那个开发环境。。。。基本没法用
不过有代码就能移植，而且，WICED里的很多代码都可以优化

不明觉厉啊，能否多放点信息？用F1和这片子的成本、功耗能到多少？

底层驱动12K，其他做全的话，估计15K。tcpip的话，如果用类似lwip规模的，大概10几K。总体32K的芯片就够了。如果做简化版本的话，16K也可能可以，不过RAM至少需要4K。

技术能够搞定的情况下，达到更高的效率，更低的成本，硬件确实用模块，不过不是简单赚串口的那种

TCPIP中的ARP，IP，UDP也搞定了，socket方式，目前占用15K flash，估计如果完整的协议栈搞定后，flash占用在25KB+。同样芯片，用lwip的话，代码占用在40KB左右，而且是callback方式。

上一些代码吧：
vsfshell_printf(output_pt, "UDP test" VSFSHELL_LINEEND);

      socket = vsfip_socket(AF_INET, IPPROTO_UDP);
      if (NULL == socket)
      {
            vsfshell_printf(output_pt, "Fail to create socket." VSFSHELL_LINEEND);
            goto handler_thread_end;
      }

      dest.sin_addr.size = 4;
      dest.sin_addr.addr.s_addr = SYS_TO_BE_U32(0xC0A80169);       // 192.168.1.105
      dest.sin_port = 10000;

      buffer = vsfip_buffer_get(64 + strlen(outmsg) + 1);
      if (NULL == buffer)
      {
            vsfshell_printf(output_pt, "not enough resources." VSFSHELL_LINEEND);
            goto handler_thread_end;
      }
      buffer->start += 64;
      buffer->len -= 64;
      bufptr = vsfip_buffer_ptr(buffer);
      strcpy((char *)bufptr, outmsg);
      local_pt.state = 0;
      vsfsm_pt_entry(pt);
      err = vsfip_udp_send(&local_pt, evt, socket, &dest, buffer);
      if (err < 0)
      {
            vsfshell_printf(output_pt, "Fail to send UDP" VSFSHELL_LINEEND);
            goto handler_thread_end;
      }
      if (err != 0) return err;
      vsfip_buffer_release(buffer);

      vsfshell_printf(output_pt, "UDP tested OK" VSFSHELL_LINEEND);

简单的UDP测试代码，建立socket，分配缓冲，设置远程的地址和端口，发送。。。。
