Thank you for continued help!! I am not using any diodes. I didn't think they were needed as I can use the code (which I have updated below based on your help and in another thread) and I can see all 56 (64 once rotary code is added) button presses as well as able to press buttons simultaneously with no issues. The 32 limitation I refer to is when you open game controller properties (devices and printers) for windows the max displayed is 32 buttons and the joystick library can create multiple HID devices so I split the matrixes into 2 8x8s giving me 32 buttons per "controller".
Since this does eat up 16 wires I only have 4 inputs left which is where I thought the IO expander would come into play giving me 12 analog inputs to use for the 2 3-axis controllers or use the analogs on the LEO for the joysticks and the 16 pins on the expander for the matrixes.
I'm definitely open to suggestions on getting this completed.
