Buttons

[n8layman]

The current plan is 2 1x4 neokey strips. That gives me 8 keys to work with. The current plan is:

• [ ] Position / Jog (2 states) Hold and Lock at the same time to change mode
• [ ] Metric / Imperial (states) Hold and Lock at the same time to switch native units. Press on its own without Lock to change the view without changing native units.
• [ ] Fast / Slow (2 states) Hold and Lock at the same time to change speed
• [ ] Zero (Interrupt) Hold and Lock at the same time
• [ ] Top (Interrupt) Hold and Lock at the same time
• [ ] Bottom (Interrupt) Hold and Lock at the same time
• [ ] Move to Position (Interrupt) Hold and Lock at the same time to move
• [ ] Lock (Interrupt rising edge sets flag Interrupt Interrupt falling edge clears flag)

Button triggers should be interrupt-based and update an array of button values. Changing the color of buttons should read this array in the main loop.
