怎么使用带有XC8的PIC1867J60上的TCP/IP

下面的链接提供了使用McC.HTP://www. McCHIP.COM/FUMMS/FUNDSPOT/968 699创建TCP/IP Lite项目的步骤。

谢谢你把这封信寄来。不幸的是，我不能让它为我工作。你知道有没有一些教程专门说明如何获得PIC18F67 J60（或者任何其他内置以太网硬件的芯片）作为XC8中的TCP客户端或服务器？我已经看到了许多使用SPI的EnC模块的教程，但是没有内置的硬件。

    Thank you for sending this along. Unfortunately, I can't seem to get it to work for me. 
 
Do you know if there are any tutorials specifically showing how to get a PIC18F67J60 (or any other chip with built in Ethernet hardware) to act as a TCP client or server in XC8?
 
I have seen a number of tutorials using the ENC modules with SPI, but nothing with the built in hardware.

嗨，我按照上面的说明使用MCC V3.264为EXXXJ6X生成了一个Lite堆栈。我尝试从2015将生成的代码调整到ECHO服务器应用程序。应用程序完全不可用！有人曾经成功地使用MCC生成一个功能性的LITTCP/IP协议栈吗？如果有人给我指出一个类似于2015的新功能演示应用程序，我将不胜感激。谢谢，伊凡

    Hi,
 
I generated a Lite Stack for ETHxxJ6x using MCC v3.26.4 following the above instructions. I tried to adjust the generated code to the Echo Server Application from 2015.
The Application is completely non-functional!
 
Did anyone ever succeed to generate a functional Lite TCP/IP stack using MCC? I’ll appreciate if somebody points me to a new functional Demo Application similar to that one from 2015.
 
Thanks,
Ivan

这对我也不管用。我现在有一个关于这个话题的微芯片支持的案例。如果我学到任何新东西，我会把这篇文章更新到最新的。值得注意的一点是TCP/IP Lite没有正式支持PIC18F67 J60.AN1921有一个支持的硅产品列表：HTTP://www. McCHIP.COM//WavaPabeSe/AppNo.ASPX？APPNTENEn9340与PIC18F47 K40的Enc8J60大约是一个PIC18F67 J60的相同价格。因此，这可能是一个合理的尝试，但是，我还没有走向那个方向。如果你被限制在时间上，你可能想看看WiZNET W5500芯片。它们是非常了不起的，因为它们在飞机上实现了TCP协议栈，而且价格相对低廉。如果您的板空间允许，它们很容易与之连接。在W5500上实现TCP可以让您在所选择的处理器上节省大量的预算。ATMGA328 P或PIC18F26K40与W5500的网络接入是我正在试验的一条路线。

    It does not work for me either. I currently have a case open with Microchip support about this topic. I'll keep this post up to date if I learn anything new. One thing to be noted is that TCP/IP Lite does not officially support the PIC18f67j60. 
 
AN1921 has a list of supported silicon products: http://www.microchip.com//wwwAppNotes/AppNotes.aspx?appnote=en573940
 
The ENC28j60 with a PIC18f47k40 is about the same price as one PIC18f67j60. So that may be a reasonable route to try, however, I have not gone that direction yet.
 
If you're constrained on time, you may want to take a look at the Wiznet W5500 chips. They are pretty great since they implement the TCP stack onboard and are relatively inexpensive. If your board space allows, they are quite easy to interface with. Implementing TCP on the W5500 lets you save a good amount of your budget on the processor you choose. ATMega328p or PIC18f26k40 with the W5500 for network access is a route I'm experimenting with.

谢谢你的建议。事实上，我有一个基于PIC16F67 J60的功能以太网到串行转换器（HTTP://www. MigCHIP.COM/FUMMS/M964 730.ASPX）和demo应用程序，来自2015的AN1921源代码。但是下载数据非常慢。一个文件可以下载15秒，通过使用RS-232或USB到串行。使用以太网到串行设备下载同一个文件需要6分钟以上。我了解到PIC18F67 J60的以太网PHY是10BASE-T，但我很好奇，是否有可能用MCC生成的更新的Lite堆栈使应用程序更快。这就是我开始挖掘MCC产生的原因的原因。伊凡

    Thank you for the suggestion. I’ll look at W5500.
 
As a matter of fact I have a functional Ethernet-to-Serial Converter (http://www.microchip.com/forums/m964730.aspx) based on PIC16F67J60 and the Demo Application, which comes with the AN1921 Source code from 2015.
 
The speed of my Ethernet-to-Serial is acceptable for control messages but it is extremely slow when downloading data. A file can be downloaded for 15 seconds by using either RS-232 or USB-to-Serial. Downloading the same file using the Ethernet-to-Serial takes more than 6 minutes.
 
I understand that the Ethernet PHY with PIC18F67J60 is 10Base-T but I’m curious if it is possible to make the application faster with an updated Lite Stack generated by MCC. This is the reason I started digging to whatever MCC has generated.
