Prepping for version 4.1 SERVO_SIGNAL definition in EXRAIL SERVO_SIGNAL(vpin, redpos, amberpos, greenpos) use RED/AMBER/GREEN as for led signals. * SIGNALH, ATGTE, ATLT UNTESTED * Automatic ALIAS(name) and _ in keywords * EXRAIL FORGET current loco * EXRAIL </KILL ALL> * EXRAIL VIRTUAL_TURNOUT * Cleanup version.h * Update version.h (#223) Rewrite & Updated the 4.0.0 Section * </KILL ALL> fix * Incoming LCN turnout throw. * KILLALL macro and DIAGNOSTIC messages when KILL command used. * EXRAIL PARSE * Rebuild throttle info getters UNTESTED... create different methods to obtain throttle info without being withrottle specific. Also implements turnout description of "*" as hidden. * J command parsing JA JR JT commands parsed EXRAIL sets hidden turnout state HIDDEN description macro Turnouts hidden flag bit UNO seems OK, MEGA UNTESTED * Assist notes draft & syntax tweaks * Throttle notes * uno memory saver * JA JR and <t cab> * Subtle corrections * Update version.h * I2C code corrections Corrections to I2C code: 1) I2CManager_Mega4809.h: Correct bitwise 'and' to logical 'and' - no impact. 2) I2CManager_Wire.h: Ensure that error codes from Wire subsystem are passed back to caller in queueRequest(). * RAG Ifs and cmds * IF block perf/memory * Allow negative route ids. * correct GREEN keyword * Update version.h * myFilter auto detect * Update version.h * fix weak ref to myFilter * ACK defaults now 50-2000-20000 * Update version.h * Improved SIGNALs startup and diagnostics * Update IO_PCA9685.cpp * Allow turnout id 0 * Position servo pin used as GPIO * NoPowerOff LEDS * CALLBACK parameter optional for Write * WRITE CV ON PROG <W CV VALUE> Callback parameters are now optional on PROG * Updated CV read command <R cv> Equivalent to <V cv 0> uses the verify callback.
