I am happy to announce that @matthew.gregg has taken the skeleton of the platform I have been developing and massaged it enough to get it working with Assetto Corsa! Using the STM Disco board and MMoS game controller integrated with my FOC software for stepper motors Matt is shown below making some laps with his good looking DD wheel.

I have to give Matt a lot of credit, he took a lot of his own time to work on this project, even when I hadn't touched it for months. He has also provided invaluable information for the design of the system. 

Matt has also inspired me to finish the latest PCB design for the project, which is a motherboard to integrate all of the motor control components as well as add connection for the G27 shifter and Pedals. I should receive the prototype for the motherboard in a couple days so that I can begin testing.  For now, here is a sneak peek at the MOBO. If it ends up working, I'd like to make it available to fellow DIYers! BTW the website on the board is under construction and not available yet.
