claytonk 0:605fe136b7ea 18 FEATURE REQUIREMENTS
claytonk 0:605fe136b7ea 19
claytonk 3:6b14862f5f51 20 - I2C write occurs on falling edge of strobe pulse to prevent unknown states
claytonk 3:6b14862f5f51 21
claytonk 3:6b14862f5f51 22 - Stack check occurs on leading edge of strobe pulse to ensure strobes are
claytonk 3:6b14862f5f51 23 set correctly
claytonk 0:605fe136b7ea 24
claytonk 3:6b14862f5f51 25 - Reoccuring enable from app that will prevent the emitters from remaining
claytonk 3:6b14862f5f51 26 on if the app crashes and a turn off command isn't sent
claytonk 0:605fe136b7ea 27 - Can be a counter on the emitter enable > threshold
claytonk 3:6b14862f5f51 28 - Better if it's a counter based on reads from the fault register
claytonk 0:605fe136b7ea 29
claytonk 0:605fe136b7ea 30 -Flood/Dot tagging indicated on GPIO3
claytonk 0:605fe136b7ea 31 - 0 Flood
claytonk 0:605fe136b7ea 32 - 1 DOT
claytonk 0:605fe136b7ea 33
claytonk 0:605fe136b7ea 34 -Fault indication on GPIO4 to indicate to app to reboot
claytonk 0:605fe136b7ea 35 - 0 OK
claytonk 0:605fe136b7ea 36 - 1 Fault/Reboot
