To those whose attention this topic has drawn:
I'm currently working on a "small" project to use my mega as a method of interfacing between a playstation 3 console and a playstation dualshock controller. At this point, you're thinking... why do this since the two are already playing nice... however, I was curious as to if it could be done so as to select particular inputs and outputs to send them wirelessly to another device.
I had started the project out earlier working with the wireless part and exploring RF and bluetooth transmissions, but that just developed into investigating how to listen in on communication that was already occurring between devices. In that process I came to the point where I was experimenting with the unojoy library in conjunction with a usb host shield library that allowed me to effectively set up a controller that would talk to my mega, and the mega which could talk to a console (or pc). However, as far as I understand the unojoy library as well as the usb host shield library are effective 2 way communications from the user to the device. However, I'm running into a real issue regarding 1. how to request and decode signals from the ps3, and particularly those associated with force feedback since that seems to be the only aspect lacking of duplicating the effects of a dualshock controller, and 2. to actually confirm if I'm understanding how the unojoy library communicates with the ps3. Any help or direction are most appreciated at this point as it feels like the project is "near" completion, but lacks that essential element to let me sleep at night.
