How can I write a C program to connect to a controller.
I have some reference about the controller.
it has ethernet port. I can use "sendto" and "recvfrom" get code and send code.
Is it UDP?
I tried to use UDP client pragram to connect it. But I cannot connect.
The header has problems.
Can I download the header? Or download the sample?
Anyone have sample about connect a controller from ethernet port?
