If you got any question about ENC28J60 and SPI ask it here in this friendly forum. I check this forum every day (and also learning a lot from it).

Have fun

If you choose Ethernet than there are some routines you can't do without. You need at least ARP, Address Resultion Protocol. To get the MAC-address belonging to a IP-number. You could just use the UDP-protocol (connectionless) instead of TCP, the first one only shouts your information on the netwerk and hopes it will arrive. The TCP uses a session and you can be sure your data will arrive.

Perhaps you could consider something more easy to use if ethernet is to difficult. RF, serial...

Have fun

Hi All

There seems to be a problem with the code I wrote for the ENC28J60. On the Bascom-AVR version prior 1.11.91 everything works fine, on newer versions the SPI as I used it in the program doesn't seem to work anymore. I have contacted MCS about this and got some hints to solve this problem. Using SPImove instead of the SPI-commands I am using now. Will have a good look at it at make some corrections in the program.

Hi Ben,

whats happen with the tcp_ack=0 and the tcp_psh=0 ?
Is that a SPI-Error?

I would like to programm a WebServer with the Pollin-Board.
Next i would like to Send UDP and Receive UDP-Messages!

Receiveing work! But sendig does not work well. My prob is understanding your code! It wile be fine if i know how to write a routine like

Sub UDP_Send(dest-ip-adress,nuber of bytes to send,SendigBytes())
or
Sub UDP_Send(dest-ip-adress,nuber of bytes to send)

Sendig Byte is like dim TrxByte(255) as byte.

Greeting Alex
