Device commands

The 1-Command is used by the device to send commands to SPAD.neXt.

Request: 1,<SUBCOMMAND>,...;
Reply: none or 2,ERROR
Provide Data to SPAD.neXt
The subcommand ADD informs SPAD.neXt about a data value the device will provide. This data can be used in events or expressions like any simulation data in the SPAD.neXt UI.

 1,ADD,<CHANNELID>,<path>,<valuetype>,<access>,<name>[[,description][,options]];
Parameter
Description
Limits
<CHANNELID>
the Channel the device/SPAD.neXt will use to send updates for that data
>= 10
<path>
 name of the data value. 
To place it in a tree "//" can be used to separate the nodes. e.g. buttons//button1 (note the escaped "/" !!
If using CmdMessenger-Lib the escaping will be done automatically for you)
name must not start with /
<valuetype>
type of the data (Signed/Unsigned)
S8 S16 S32 S64 U8 U16 U32 U64 FLT32 FLT64 ASCIIZ
<acces>
RO for readonly, RW for readwrite
​
<name>
human readable name of the data for the UI
​
<description>
optional description for the UI
​
Supported options
PERSIST
0|1
0 create LOCAL variable (default)
1 Create a persistent DEVICE variable
PERSIST=1
Within SPAD.neXt the data will be available in Device->Devicename. 
Internally the Data is referenced as DEVICE:{DeviceId}/<path> 
e.g.  DEVICE:A8AA15C5-7BB6-4AC6-A558-A88CAFB78729/buttons/button1
Device Data is only available within the profile of the device. 
Getting and setting
SPAD.neXt will send data updates to the device and expect data using the given CHANNELID channel using the 5-Channel: 5,<CHANNELID>,<value>; 

Examples
Persitent Device Variable
1,ADD,11,pages//activepage,U8,RW,Active device page,My cool description,PERSIST=1;
creates a variable DEVICE:VID/PID/pages/activepage available only within the deviceperofile of the device. outside of the deviceprofile this variable will always have the value 0
Normal non-persistent local variable
1,ADD,11,pages//activepage,U8,RW,Active device page;
creates a variable LOCAL:VID/PID/SERIAL/pages/activepage available to all deviceprofiles within SPAD.neXt
DEVICE variables are persitent per connected devices and the values will be loaded and saved from/to the profile.  
LOCAL variables will not be saved and default to 0 
​
Subscribe to a data 
the subcommand SUBSCRIBE with subscribe the device to a data value from SPAD.neXt or the simulation

1,SUBSCRIBE,<index>,<path>[,<unit>[,<epsilon>]];
<index>
the index associated with the data
<path>
internal name of the data value to subscribe to. E.g. SIMCONNECT:AUTOPILOT HEADING LOCK DIR XPLANE:SIM/COCKPIT/AUTOPILOT/HEADING_MAG
<unit>
desired unit, if not default (e.g. 'degrees','radians','Hz','kHz','MHz')
<epsilon>
minimum change that must happen before an update will be sent to the device. If it's omitted the default value for the data will be used
​
SPAD.neXt will send the subscribed data on the 5-Channel in the format
5,<index>,<value>;
​
Example
1,SUBSCRIBE,12,SIMCONNECT:AUTOPILOT HEADING LOCK DIR
1,SUBSCRIBE,12,SIMCONNECT:AUTOPILOT HEADING LOCK DIR,radians
1,SUBSCRIBE,12,XPLANE:sim//cockpit//autopilot//heading_mag,,5
You can get the internal name of a data value, by selecting it in the data browser and pressing CTRL-C or clicking on "book"-icon in the data monitor. It will be copied to the clipboard
Unsubscribe from a data
The subcommand UNSUBSCRIBE will unsubscribe from a previously subscribed data value
Syntax: 1,UNSUBSCRIBE,<index>;
Emulate an event on a diffrent device
The subcommand EMULATE will emulate an event from another device. (E.g. a dial turned on radio panel)

1,EMULATE,<TARGET_DEVICE>,<TARGET_SWITCH>,<TARGET_EVENT>;
<TARGET_DEVICE> is either the internal id VID:PID:COUNTER or VID:PID:SERIAL
<TARGET_SWITCH> is the internal name of the switch/dial/led etc (e.g. FIP_LEFTDIAL)
<TARGET_EVENT> is name of the event to emulate (e.g. TUNER_CLOCKWISE)
To get the TARGET_SWITCH and TARGET_EVENT you can program the event in the UI and then copy the complete event to the clipboard, pasting to a texteditor.
The TARGET_SWITCH will be the "BOUNDTO" and the TARGET_EVENT the "Trigger"
Alternatively you can get a list of all devices and events at Settings->Application->Expert->Available Remote Events
Update the labeltext of an input/output or label
1,LABEL,<index>,<newlabel>;
Updates the labeltext of a input/led (DYNLABEL=1 !) or a label pseudo input
Ask SPAD.neXt to resend all subscribed data
1,REFRESHDATA;
SPAD.neXt will send all currently subscribed data
