The following code does not work. If you have a friend who can run, please help me.
I tried the C code of the library, is compiled without problems.
but not compiled Basic code.
Code: Select all
program HTTP_Demo_28j60

' * description :
' * this code shows how to use the Net_Ethernet_28j60 library :
' * the board will reply to ARP & ICMP echo requests
' * the board will reply to UDP requests on any port :
' * returns the request in upper char with a header made of remote host IP & port number
' * the board will reply to HTTP requests on port 80.

' * Test configuration:

' * NOTES:
' - External power supply should be used due to Serial Ethernet Board power consumption.
' - Because page contains 4 images, We need minimum 5 socket (defined in _Lib_NetEthEnc28j60_Defs.c file), one for HTML page
' and one for each image.
