// Changed time between temp calls to 5s from 10s
//
// v1.44_XXX 14072015
// Major changes in GZ/GT calls, return last temp if focuser is moving, also if new temp call is
// received less than 10s from the last one - prevents system interruo\pting moves and causing focuser

// v1.41_XXX 28052015
// Minor fixes
//
// v1.40_XXX 25052015
// On a :FQ (Halt), will write position to EEPROM after delay (in case user turns off focuser later on without any further moves)
// On powerup, both LED IN/OUT now light up with Buzzer On to indicate boot up cycle
//
// v139_XXX 08052015

// Changes to displaylcd() re stepmode
//
// v1.34_XXX 16032015
// Test changes for INDI moonlite focuser
// Added gotonewposition variable, used with SN followed by FG (Moonlite)
// Problem is that SN is causing focuser to immediately move, its not waiting for FG
// now FG sets this flag to true, and when move is complete it is reset to false
// the moving condition in the main loop now also uses this flag as a condition to move
// Added GC for moonlite
// Changed maxFocuserLimit to 60000 for be compatible with moonlite
//
// v1.33_XXX 20022015
// changed Maxsteps and FocuserPosition to type long - On ,net and c# integers are 32 bit so support

// moved :GB to top of command processing to respond quicker
// added float tempoffsetval
//
// v1.30_XXX 30012014
// Changes for Coil Power, using /ENABLE to turn off power after a move
// Requires /ENABLE of DRV8825 or EASYDRIVER to be wired to D8
// Changed temperature precision of probe
//
// v1.29_XXX 03012014
// code change to ensure currentaddr does not end up with invalid value if not initialized
//
// v1.28_XXX 30122014
// Minor changes to motorSpeed and stepontime values so that 1/4 and 1/8 stepping works better
// added protocol to set motorSpeed via serial command
// fixed bug in ReverseDirection
//
// v1.27_XXX 18122014
// Minor bug fix to analogWrite() statements
//
// v1.26_XXX 13122014
// In GF, Get Firmware version, return program name and version number (ASCOM uses GV)
//
// v1.25_XXX 10122014
// Modified driver code to write values to EEPROM on SP and SM commands
// At present code only updates 30s after a move. Using the Set() commands for
// position and maxStep does not initiate a move so these would not be saved
// unless there was a move() command that followed before shutdown/power-off
// Doubtful whether user would ever actually alter these parameters like this
// scenario describes, however included just in case
//
// v1.24_XXX 01122014
// Copied from DRV8825 Minimal
// supports push buttons, LCD and temperature probe
// To work with ONE common Windows APP v1.25 and above
//
// based on some portions of original code by Dave Wells, and orly.andico@gmail.com (moonlite focuser example)
// heavily modified by RBB to work with myFocuser
