Hi
I'm a student currently working on my fourth year project, which involves controlling i/o of the PIC16F877A remotely using matrix's internet board. My problem is deciding the best option for sending messages to the board i.e. UDP, HTML, TCP etc? I realised that the memory on the 16F877A is restrictive and may limit the amount of applications I can use.
Any help or advice would be greatly appreciated.

Hey,
Thanks Steve, is there any chance you've any code you have used to implement UDP to change i/o?

Re: Tcp/ip
Sorry, Sean. I don't have any examples to hand.
The TCP/IP component has information on how to set-up UDP comms and there is more info in this in the "Embedded Internet" manual which can be found here:

Re: Tcp/ip
Thanks again Steve,
Is it possible to send UDP packets to a remote PIC using the hyperterminal or Hercules (HW Group freeware, for communicating over tcp/ip)?

Re: Tcp/ip
There are tools that you can use to send and receive data over the network. But be aware that when receiving or "snooping" on ethernet traffic that a hub will usually filter out messages that are not intended for the IP of your PC.
