This week, I fully implemented the hardware interface for UNO. We were able to start testing full UNO games using the machine this week. We ran into several weird bugs involving the TkInter based GUI and the hardware IO as the GUI stopped working once we switched to using the hardware controller. Jason and I finally fixed this issue after we forced the Tk display to update in a blocking manner instead of non blocking as usual. Also, our current implementation relies on blocking IO which polls the various buttons and serial interfaces. We started switching this over to an async approach which spins up another thread to do the polling. Also, the issue with the GUI should go away once we switch to a website interface which will have its server running in a different process.
I am on schedule. Next week I plan to finish switching the code over to non blocking IO and to start work on the website with Jason.
