Complete revision:(Many changes summarized)
Added Slope/intercept calculation
    -selectable w/ radiobutton
Datatable and Gridview
    -stored in SQL database
Added max/min HFR selection to mark linear portion of v-curve
Goto focus moves to near focus position then based on that HFR, goes to best focus
    -stays on one side of focus point so no need for backalsh compensation
    -can select use of up or down side
Automatically connects to single port
    -connect button turns green
Added 6 equipment selections
    -stored in settings
Maintains directory in settings with closing
Movement delay helps prevent movement during capture

More Arduino Updates

Finished Direction toggle
    -toggles directions by entering 0 or 1, useses EEPROM storage
    -added error handling
Added escape using # to go back in menus

Several Arduino Updates -- Close to final version

Added goto progress bar
Added second page of setup menu (#,#,D gets there) 
    -Backlash compensation (number of steps) stored in EEPROM
    -Adjust stepper delay ("wait") =  stepper pulse width/1000 in microseconds 
    -Direction control (pending)
Fixed stepper delay discrepancy with goto versus encoder (now in microseconds)
Added course function to backlight adjustment with button
    -also added < zero and  exceeds maximum error message for backlight adjustment


Major Arduino Improvements

Stored positions now use EEPROM
    -no need to re-enter after power cycle
Increased motor torque
    -uses a standby function so enable stays on until no movement for 1 second
Setup Menu (press #,#)
    -adjust backlight w/ rotary encoder
    -set maximum travel (stored in EEPROM)
    -set high speed rate
    -manual LCD display
Back to using 4x20 NetMedia LCD

Arduino Update

posted Jul 19, 2011, 5:47 AM by Astro Photo

Improved Position Sync
    -added error handling for null and high values
Established limits on Arduino for max travel
    -high speed slows when approaching zero and max travel 
    -stops at zero and max travel
    -error message if entered goto value exceed maximum travel
Fixed display pulsing
    -clears only when number of digits changes
    -Removed speed display
Improved keypad entry timing

Major Arduino Updates

posted Jun 30, 2011, 8:02 AM by Astro Photo

Added Button on rotary encoder box to enable high speed
    -momentary (nl. open) push-button connects SpeedSelectPin to ground
    -twenty steps per click
Added keypad (4x4) for improved manual control
    -ABCD keys are preset focus points
    -Push letter to store location, push again to confirm, "*" to abort
    -Manual goto position entry by pushing "#" follow numeric position or preset ABC or D from above
