// 5.2.34 - <A address aspect> Command fopr DCC Extended Accessories.
This command sends an extended accessory packet to the track, Normally used to set
a signal aspect. Aspect numbers are undefined as sdtandards except for 0 which is
always considered a stop.
// - Exrail ASPECT(address,aspect) for above.
The ASPECT command sents an aspect to a DCC accessory using the same logic as
<A aspect address>.
// - EXRAIL DCCX_SIGNAL(Address,redAspect,amberAspect,greenAspect)
This defines a signal (with id same as dcc address) that can be operated
by the RED/AMBER/GREEN commands. In each case the command uses the signal
address to refer to the signal and the aspect chosen depends on the use of the RED
AMBER or GREEN command sent. Other aspects may be sent but will require the
direct use of the ASPECT command.
The IFRED/IFAMBER/IFGREEN and ONRED/ONAMBER/ONGREEN commands contunue to operate
as for any other signal type. It is important to be aware that use of the ASPECT
or <A> commands will correctly set the IF flags and call the ON handlers if ASPECT
is used to set one of the three aspects defined in the DCCX_SIGNAL command.
Direct use of other aspects does not affect the signal flags.
ASPECT and <A> can be used withput defining any signal if tyhe flag management or
ON event handlers are not required.
// 5.2.33 - Exrail CONFIGURE_SERVO(vpin,pos1,pos2,profile)
This macro offsers a more convenient way of performing the HAL call in halSetup.h
In halSetup.h --- IODevice::configureServo(101,300,400,PCA9685::slow);
In myAutomation.h --- CONFIGURE_SERVO(101,300,400,slow)
// 5.2.32 - Railcom Cutout (Initial trial Mega2560 only)
This cutout will only work on a Mega2560 with a single EX8874 motor shield
configured in the normal way with the main track brake pin on pin 9.
<C RAILCOM ON> Turns on the cutout mechanism.
<C RAILCOM OFF> Tirns off the cutout. (This is the default)
<C RAILCOM DEBUG> ONLY to be used by developers used for waveform diagnostics.
(In DEBUG mode the main track idle packets are replaced with reset packets, This
makes it far easier to see the preambles and cutouts on a logic analyser or scope.)
// 5.2.31 - Exrail JMRI_SENSOR(vpin [,count]) creates <S> types.
This Macro causes the creation of JMRI <S> type sensors in a way that is
simpler than repeating lines of <S> commands.
JMRI_SENSOR(100) is equenvelant to <S 100 100 1>
JMRI_SENSOR(100,16) will create <S> type sensors for vpins 100-115.
// 5.2.26 - Silently ignore overridden HAL defaults
// - include HAL_IGNORE_DEFAULTS macro in EXRAIL
The HAL_IGNORE_DEFAULTS command, anywhere in myAutomation.h will
prevent the startup code from trying the default I2C sensors/servos.
// 5.2.24 - Exrail macro asserts to catch
// : duplicate/missing automation/route/sequence/call ids
// : latches and reserves out of range
// : speeds out of range
Causes compiler time messages for EXRAIL issues that would normally
only be discovered by things going wrong at run time.
// 5.2.13 - EXRAIL STEALTH
Permits a certain level of C++ code to be embedded as a single step in
an exrail sequence. Serious engineers only.
// 5.2.9 - EXRAIL STASH feature
// - Added ROUTE_DISABLED macro in EXRAIL
