Eye_SIG Contains: EYEFRM SIG_CTRL
EYEFRM Functional: determines whether or not the eye is closed.
SIG_CTRL EYECLOSED Functional: determines if the eye has been closed for 2 sec. Includes 5 states: Counting, EyeCWait, DoneCnt, ACKwait, and FRMwait
SIG_CTRL (Cont.) Counting CameraFrame Asserted and Count < 40 Compare With CALIB and Return CameraFrames = 40 EyeCWait Less Than 38 / 40 EyeClosed Signals Asserted DoneCnt ACK Signal From 8051 CameraFrame Asserted CameraFrame Asserted At least 38 / 40 EyeClosed Signals Asserted ACKwait ACK Signal From 8051 & CameraFrame Not Asserted FRMwait
Suggestion - Add extra pins to choose which control states to switch to. (cyclic order for now) | | | time 2sec - After eye is closed for 2 sec, require that the eye to open before starting counting again.
