:) Hello Guys!

I hope you can help me with some doubts.

I am programming the Digilent card to use with internet, however the library the Chipkitethernet library is showing the following errors:

Some time ago I had compiled this code in MPIDE and it worked, but I changed the computer and lost the libraries and MPIDE. Now I'm having this error.

In file included from program_murilo.cpp:3:0: C:\Users\LSI\Documents\mpide\program_murilo/chipKITEthernet.h:109:18: error: conflicting return type specified for 'virtual void Client::write(uint8_t)' C:\Users\LSI\Desktop\Murillo Gentil\mpide\mpide-0150\hardware\pic32\cores\pic32/Print.h:48:20: error: overriding 'virtual size_t Print::write(uint8_t)' C:\Users\LSI\Documents\mpide\program_murilo/chipKITEthernet.h:111:18: error: conflicting return type specified for 'virtual void Client::write(const uint8_t*, size_t)' C:\Users\LSI\Desktop\Murillo Gentil\mpide\mpide-0150\hardware\pic32\cores\pic32/Print.h:53:20: error: overriding 'virtual size_t Print::write(const uint8_t*, size_t)' C:\Users\LSI\Documents\mpide\program_murilo/chipKITEthernet.h:147:16: error: conflicting return type specified for 'virtual void Server::write(uint8_t)' C:\Users\LSI\Desktop\Murillo Gentil\mpide\mpide-0150\hardware\pic32\cores\pic32/Print.h:48:20: error: overriding 'virtual size_t Print::write(uint8_t)' C:\Users\LSI\Documents\mpide\program_murilo/chipKITEthernet.h:149:16: error: conflicting return type specified for 'virtual void Server::write(const uint8_t*, size_t)' C:\Users\LSI\Desktop\Murillo Gentil\mpide\mpide-0150\hardware\pic32\cores\pic32/Print.h:53:20: error: overriding 'virtual size_t Print::write(const uint8_t*, size_t)'

somebody coud help me?

Where from, and how long ago, did you download the library?

Also I think that library isn't supported any more. The chipKIT Core comes with DEIPcK that is the current incarnation of the networking stack.

Hello, the library downloaded the following site: Https://github.com/majenkotech/chipKITEthernet

It's been a little over a month since I'm trying to use it.

I needed this library to work, because my code is all in function of such a library.

Could you tell me where I could get a compatible library or some solution so I do not have to change the code?

Thank you

That is ancient code. Really ancient. I haven't touched that for 4 years, and the Arduino API has changed lots in that time.

It was basically a copy and adjustment of the code found on here: https://reference.digilentinc.com/chipkit_shield_network:chipkit_shield_network - you can maybe get it going with that library instead.

Hello, through the link you sent get the chipkit ethernet library and with that all the errors were solved.

The code worked !! Thanks for all the help !!!!!

Hi, I'm having a similar kind of problem, but being a newbie this is even harder. I've just bought a second hand mx7ck board as I have an idea to send/grab data to/from a MySQL database. Right now I'm just starting to try the board and the first test would be the webclient example but I'm having a real nightmare trying to, at least, compile it. I've followed all the steps, changing mac address, ip, subnet and mask to the correct ones but it doesn't even compile. Right now I got to the point of having an error where it requests it says: "plib.h: No such file or directory". I have also followed the steps for installing everything from scratch but nothing... Can you help me? Thanks in advance.

Hi, This discussion was pretty much the same 'flavour' of this one

chipkit mx7ck calling "hello world" from webserver [url]http://chipkit.net/forum/viewtopic.php?f=17&t=3814[/url]

So have a look there please. Thx

Hello friend, I had the same problem ...

I think your problem is in library compatibility.

At the link shown above, we have a library that can solve your problem. Any questions leave your email that I will contact

The problem here is that Digilent haven't updated their library to work with the current Arduino API (or any Arduino API since 1.0.0). The library needs re-writing so that the Print class inherited functions return the correct type - i.e., an int instead of a void. Especially the write function.

chipKIT, though, comes with a different set of network libraries built in that do work (although are rather cryptic and difficult to use it has to be said). Check out the DEIPcK and IM8720PHY libraries.

Sir,

// / Supported hardware: / / / / MX7cK / / / //

DEIPcK says the supported hardware is MX7ck , can I use this code for max32 chipkit network shield?

majenko

Sat, 28 Nov 2020 14:34:27 +0000

Yes, you can. What matters is not the board, but what chips are used. The MAX32 uses the same MCU as the MX7cK. The Ethernet shield uses the same IM8720 Ethernet PHY chip as the MX7cK.

Sir, I would like to know that if there are any libraries for CAN protocol by chipkit! Because I searched all standard libraries in arduino and could not find any libraries for chipkit network shield supporting CAN in specific! Thank you

majenko

Mon, 30 Nov 2020 16:41:38 +0000

I have no idea. CAN is not something I have ever looked at.
