1.5.3 (2016-04-29) (by Armando)
Small bugfix about encoder resolution not properly shown. Thanks to Michael Merkert for the bug report.
Improvement: Added support for H-beta and S-II filters
Bugfix: handbox focuser Get button now works also with no caliper in use.
Bugfix: focuser movement command to invalid position is now discarded.
Bugfix: mount parameters are properly stored.
Bugfix: West/East toggle by telescope now causes Dec inversion if the mount is not aligned.
Bugfix: all mount parameters are now properly stored.
Bugfix: short LX200 coordinate format causes no warning message at startup.
Small bugfix: Added two sleep calls to solve possible issues at startup.
Improvement: To solve possible time related communication issues an overloaded CommandString function is now implemented to wait for the length of the expected answer. Currently it's used only to get latitude and longitude.
Improvement: overloaded CommandString with two new parameters (expected answer length and a timeout multiplier). Currently only some commands make use of them.
Bugfix: TelescopeMove now works also with encoder AutoSync enabled.
Bugfix: changing tracking rate when mount is parked causes no crashes.
Improvement: Added 2x, 8x and 16x paddle speeds. Selecting these speeds or guiding rate will cause no LFEP internal memory writings.
Bugfix: Dec 16x speed setting is no more overwritten by 16x RA speed by Stop function.
Improvement: Added warning message as soon as a new moving speed that will cause EEPROM writings has been selected.
New feature: Added sound notification on slewing end.
New feature: Added Silent mode to reduce traffic (useful while guiding by ST4).
Improvement: RA and Dec coordinates are now updated every 1s while telescope is slewing.
Improvement: RA and Dec coordinates are updated as soon as a manual moving command ends.
New feature: added weather panel. Temperature, dew point, humidity and cloud values are properly shown.
New feature: a right click on the log panel will keep only the last 10 log lines.
Improvement: Small GUI changes to reduce the GUI size.
Changes: Focuser Get button replaced by mouse double click on focuser position.
Changes: Focuser Fast/Slow button replaced by mouse double click on focuser speed.
Bugfix: wrong encoder autosync tolerance check.
Improvement: disabled LF_GetPECstatus call when not required.
Small BugFix: wrong values of SYNC distances were logged.
Small Bugfix: parking status is properly shown/updated when a parking/unparking command has been sent by Telescope setup.
New feature: added reverse pier side mode.
Small BugFix: flip button status is no more affected by autoflip settings.
Small bugfix: CaliperRes, FocThreshold and StepSize decimal separator format.
Improvement: added _ManualSlewing to properly manage/update position while pressing a moving button (by ASCOM handbox).
Small bugfix: whatever the SideOfPier, MoveNorth and MoveSouth move the mount in the right direction.
BugFix: SideOfPier by ASCOM and by hardware handbox are the same. (*3)
New feature: drift compensation.
Small Bugfix: KingRate and PEC status caching didn't work.
Improvement: implemented emptyInBuffer to discard unexpected data and process coordinates sent by hardware handbox.
Improvement: each command is resent if unexpected data is still available after the readout.
Bugfix: #14:VX# answer length is 8 bytes - LFEP BUG.
Bugfix: 89.90 as FlipPointToPole flipDEOver parameter value to be sure meridian is not crossed before FlipCrossMeridian execution.
Bugfix: MoveNorth and MoveSouth modified to manage LFEP bug (wrong Dec direction on West Side of Pier).
New feature: flip through South Pole.
Improvement: flip should cause no pillar collision.
Improvement: IntellyTrack can be kept disabled if marked by the user as buggy.
Improvement: manual flip is now always possible.
Small bugfix: SetAutoguiderRate.
Improvement: no display status check (display causes issues no more) and no long format switch at start-up.
===>>> New feature: partial FW5 support <<<===
===>>> FW5 LFEP can be configured only by handbox! <<<===
Improvement: manual flip is now managed by a timer.
Bugfix: async slewing command didn't return immediately in case of autoflip.
Now all async slewing steps are managed by a timer.
Bugfix: slewing state kept on during the entire slewing time (including Pole cross and final slew required in case of autoflip).
Small bugfix: flipping kept on during all flipping time.
Small bugfix: slewing distance check if enabled is active even if horizon check is disabled.
New feature: added alternative parking position.
Reorganized all LFEP ASCOM profile settings related to flipping and parking
===>>> Check driver configuration after <<<===
===>>> updating from previous releases! <<<===
Redefined flip and parking options:
- Removed Controller parking mode.
- Flip through N, S and N/S (N/S mode requires confirmation).
- Independent auto flip option for GoTo (with/without confirmation).
- Independent auto flip option for parking (with/without confirmation).
- Independent horizon check options for parking and slewing.
New feature: focuser speed is stored/restored upon connection.
New feature: focusing not possible while parking/slewing.
Small bugfix: focuser speed is equal to value shown/set by LFEP handbox.
Small bugfix: time was not properly stored (because of wrong time format).
New feature: added fan button to control fan by handbox.
Small bugfix: SyncToTarget sets _Aligned.
Small bugfix: UnparkTracking option was ignored - added sleep call in _AtPark.
Improvement: horizon check, if enabled, occurs also when setting parking positions.
Removed EPEC support.
Several bug fixes and changes.
A new option is available to enable/disable slewing management by the driver. (*6)
Keeping the Enhanced slewing control option enabled can be useful to prevent pillar collisions but the LFEP is to be properly configured according to the instructions available at the following address:
1. In case of no LFEP communication issues I would suggest to set a lower timeout value (750 - 1000).
2. Implementation of PulseGuide is not ASCOM compliant. As for example, If you're using Maxim DL you have to enable Auto Pier Flip (in guide panel) and Reverse X in Guider Motor Control settings (Guider advanced settings) to eliminate the need of new guider calibrations after a flip...
3. SideOfPier by ASCOM and by hardware handbox are the same only if Dec motor rotation is not reversed.
4. If you guide by the ST-4 interface then LFEP guides only at pad guide speed. So guiding speeds grater than 1x are only available by ASCOM pulse guide!
5. ASCOM pulse guide speeds greater than 1x are affected by a bug: guiding to East is faster than guiding to West (if n*x is the expected guiding speed the effective speed isn't 1x+-n*x but +-n*x).
6. Enhanced slewing management has been developed by taking care of telescope distance from pillar for users on the Northern Emisphere.
1.5.2 (2013-03-21) (by Armando)
Fixed _ForceRightAscension and -Declination update in remote controlled mode
Added polar scope led brightness control - Focuser Position Readout Extension required
Added help file (by Stefan)
Changed dome driver to be compatible with ACP
Several fixes by Armando related to the caliper
Fixed an error where the handbox stops refreshing occasionally
New: Added SlewSettleTime and a new GUI field in SetupDialog (Backlash tab). Tested with ACP.
Fixed Google Maps URL for southern hemisphere
New: Support for GuideRateDeclination and -RightAscension. Necessary for SmartTrack (see http://winfij.homeip.net/maximdl/smarttrack.html)
Focuser (mostly caliper relevant changes by Armando):
Moved caliper communication to a different thread.
Added caliper reading delay. It will be user defined later.
Added max allowed focuser movement (with caliper in use). It will be user defined later.
Added GUI command to set focusing filters offset values;
Firmware check (for SilentMode support) only with LFE connected

Set LastReading and LastShift to 0 if not set, check Firmware >= 6.2 for caliper silent mode
Added the ability to keep the absolute focuser position when a caliper power cycle occurs.
Changed PierEast and PierWest. This was necessary to be conform with ACP.
The nomenclature of ACP states:
PierWest = telescope is on the west and facing east
PierEast = telescope is on the east and facing west
The ASCOM / ACP designation for the meridian side is therefore inverse to the LFEP's handbox

Updated LFEP Starter to 1.2
Set mount to parking state at disconnect when AtPark=true. This handles an issue when the controller was not explicitly set to parking at the end of a session.
Check controller "aligned" state for automatic resync
Solved an issue where the process does not exit after disconnecting
Bugfix: Re-align to parked position only when AtPark
Implemented AltAz ASCOM methods
Added elevation to location tab
Fixed bug at detection of possible manual interruption
Added safety limits (horizon limit, max. slew distance)
fixed bug in angular distance calculation
Check Alt/Az coordinates against parked position, if distance is greater 2Â° then consider telescope has lost alignment
Increased tolerance after slew for parking/meridian flip from 0.5 to 1Â°
Changed log message for SyncToCoordinates to display delta in degrees.
Dome: Changed parked telescope validation to messagebox instead of exception
Better detection of lost alignment.
Added logging to Resync procedure.
Improved detection of user interrupted meridian flip and parking procedure
Tracking now raises an exception whent AtPark only when going to true (for ACP)
Removed the main form
