Hello, I'm working on a project where I need to control nearly 100 LED's between two Raspberry Pi's. For this, I'm using two B+ Pi's, seven IO Pi Plus boards from AB Electronics (https://www.abelectronics.co.uk/p/54/io-pi-plus
), one Ethernet cable (standard cable, a cross-over is not needed) and several 16-channel relay boards from SainSmart. Everything is connected and I can locally control the relays from each Pi with no problem. I have the main Pi set up as the "client" and the other one set up as the "server" waiting for commands over the socket connection.
Ideally, I would like to control the entire system through one Pi (likely the client) and have no perceptible delay between boards. This will allow me to create the needed effects with the LED's. Unfortunately, I haven't been able to find much information on doing so. Everything that I've found so far talks about simple communication between Pi's over the socket connection. While this is obviously important, it stops short of the commands needed to control the LED's.
Assuming people have done this, I'm hoping someone can direct me to a video or provide the needed code for this type of communication. Because there are so many LED's, I'd like to simplify the process to something as basic as "turn on 62" and let the program take it from there. That would allow be to build the LED effects I need.
Any help is appreciated.
