|
DCC++ BASE STATION supports optional OUTPUT control of any unused Arduino Pins for custom purposes.
|
|
Pins can be activited or de-activated. The default is to set ACTIVE pins HIGH and INACTIVE pins LOW.
|
|
However, this default behavior can be inverted for any pin in which case ACTIVE=LOW and INACTIVE=HIGH.
|
|
|
|
Definitions and state (ACTIVE/INACTIVE) for pins are retained in EEPROM and restored on power-up.
|
|
The default is to set each defined pin to active or inactive according to its restored state.
|
|
However, the default behavior can be modified so that any pin can be forced to be either active or inactive
|
|
upon power-up regardless of its previous state before power-down.
|
|
|
|
To have this sketch utilize one or more Arduino pins as custom outputs, first define/edit/delete
|
|
output definitions using the following variation of the "Z" command:
|
|
|
|
<Z ID PIN IFLAG>: creates a new output ID, with specified PIN and IFLAG values.
|
|
if output ID already exists, it is updated with specificed PIN and IFLAG.
|
|
note: output state will be immediately set to ACTIVE/INACTIVE and pin will be set to HIGH/LOW
|
|
according to IFLAG value specifcied (see below).
|
|
returns: <O> if successful and <X> if unsuccessful (e.g. out of memory)
|
|
|
|
<Z ID>: deletes definition of output ID
|
|
returns: <O> if successful and <X> if unsuccessful (e.g. ID does not exist)
|
|
|
|
<Z>: lists all defined output pins
|
|
returns: <Y ID PIN IFLAG STATE> for each defined output pin or <X> if no output pins defined
|
|
|
|
where
|
|
|
|
ID: the numeric ID (0-32767) of the output
|
|
PIN: the arduino pin number to use for the output
|
|
STATE: the state of the output (0=INACTIVE / 1=ACTIVE)
|
|
IFLAG: defines the operational behavior of the output based on bits 0, 1, and 2 as follows:
|
|
|
|
IFLAG, bit 0: 0 = forward operation (ACTIVE=HIGH / INACTIVE=LOW)
|
|
1 = inverted operation (ACTIVE=LOW / INACTIVE=HIGH)
|
|
|
|
IFLAG, bit 1: 0 = state of pin restored on power-up to either ACTIVE or INACTIVE depending
|
|
on state before power-down; state of pin set to INACTIVE when first created
|
|
1 = state of pin set on power-up, or when first created, to either ACTIVE of INACTIVE
|
|
depending on IFLAG, bit 2
|
|
|
|
IFLAG, bit 2: 0 = state of pin set to INACTIVE uponm power-up or when first created
|
|
1 = state of pin set to ACTIVE uponm power-up or when first created
|
|
|
|
Once all outputs have been properly defined, use the <E> command to store their definitions to EEPROM.
|
|
If you later make edits/additions/deletions to the output definitions, you must invoke the <E> command if you want those
|
|
new definitions updated in the EEPROM. You can also clear everything stored in the EEPROM by invoking the <e> command.
|
|
|
|
To change the state of outputs that have been defined use:
|
|
|
|
<Z ID STATE>: sets output ID to either ACTIVE or INACTIVE state
|
|
returns: <Y ID STATE>, or <X> if turnout ID does not exist
|
|
|
|
where
|
|
|
|
ID: the numeric ID (0-32767) of the turnout to control
|
|
STATE: the state of the output (0=INACTIVE / 1=ACTIVE)
|
|
|
|
When controlled as such, the Arduino updates and stores the direction of each output in EEPROM so
|
|
that it is retained even without power. A list of the current states of each output in the form <Y ID STATE> is generated
|
|
by this sketch whenever the <s> status command is invoked. This provides an efficient way of initializing
|
|
the state of any outputs being monitored or controlled by a separate interface or GUI program.
