28j60 + pic 18f452. Test program does not work. Help

Help please. The program does not work. I will not understand where error.

Hello,

Please can you post your entire project here, so we can inspect it.

Best regards.

[svidok]

This is my project file.

Hello,

I strongly suggest to upgrade your compiler to latest version of compiler.
Newer version has much improved Ethernet library and also TCP/IP library.

You can use import function from new compiler and check for necessary modifications in Migration document.
This way you will get latest compiler with more features and you will be able to develop projects with those new features.

Best regards.

[svidok]

So what went wrong? I tried the new version of the compiler - the same result. Help me please understand. I apologize in advance for my English. I live in the city of Kharkov in the Ukraine. I speak Russian. In matters related to the ethernet I started. So do not kick me greatly.

Hello,

Have you tried our example for Ethernet?
Also can you explain what is not working at your example?

Best regards.

[svidok]

Hello. For Ethernet I tried your example. Works, but does not suit me. I must realize questioning of port of comptroller at stated intervals and delivery in Ethernet through UDP. In my example at the input of "B" through UDP a terminal comes answer as a line of "Bigin". Nothing takes place further. Questioning of port and delivery of his value is not present. Beforehand thank you.

[svidok]

1. Your example is a server Ethernet with my device works fine, but does not suit me.
2. I need the value of port B Pic 18F452 issue through UDP to computer with a certain period.
3. What works in the example: after the character "B" from UDP terminal MikroC, the device the response is "begin".
4. What the example does not work - nothing else works. Issuance of the port is not happening. I think, that don't work function Spi_Ethernet_sendUDP.

WHY ??????

Hello,

Please can you post your project here. The one that you are having troubles with.

Hello,

I have problem with Spi_Ethernet_sendUDP when I am trying to use that function along with serial Ethernet Board, it do not send anything to the PC. The board is working with other functions.

Do you have any working code that implement Spi_Ethernet_sendUDP with PIC18F4550

Thanks

Hello,

Please can you tell me which Ethernet library are you using?
Can you confirm that your program exits Spi_Ethernet_sendUDP routine. You can check this in ICD.
Also are you incrementing Net_Ethernet_28j60_userTimerSec variable?

Best regards.

[saas123qa]

I am using the library that come with MikroC Ver 5.3

I confirm that the program exits Spi_Ethernet_sendUDP , because it excute the commands after Spi_Ethernet_sendUDP

No, I am not useing neither Net_Ethernet_28j60_userTimerSec nor SPI_Ethernet_userTimerSec

[saas123qa]

What is the benifit of using Net_Ethernet_28j60_userTimerSec or SPI_Ethernet_userTimerSec?

it is not much clear in the Help

do you have any full example of using Spi_Ethernet_sendUDP

[janko.kaljevic]

Hello,

Those two variables are same and their function is same.
The only difference between them is that one is from new Ethernet library and other is from old SPI_Ethernet library.

Best regards.
