More quartus issues later, the toolflow is finally ironed out and the networking stack is synthesized onto the DE2-115s. The sender and receiver are synthesized together onto one board and can interact with each other using keys and switches to set inputs – see the images below. At this point, partial integration can probably begin in the next couple of days. The receiver can be integrated and tested with the game logic by hardwiring sample packets on every frame when the game is active, and using the keys/switches to send game start/end packets. I’m probably gonna need another week to get GPIO communication working correctly, there’s some experimentation to be done with getting the clock working.
Leftmost two numbers represent garbage lines, the one furthest left is the lines being sent by the sender which are set using the switches, while the second one is the lines received. The two numbers in the middle represent the sequence numbers for the sender and receiver, and the rightmost number counts the total packets received.
