Device INIT-Phase
When starting SPAD.neXt will send an INIT Request to the device and expects a response within 5 seconds, else the device will be marked as offline/unavailable.
Request from SPAD.neXt:
0,INIT,<SerialVersion>,<AppVersion>,<AuthToken>
Parameters
Reply from device:
0,SPAD,<Guid>,<Name>,<SerialVersion>,<DeviceVersion>[,<opt1>,...,<optN>;
INIT-Options
available only in INIT Command. (all additional options can be added as well)
If PID option is provided, the AUTHOR option must be provided as well
AUTHOR
To receive your unique authorkey, issue the command "!deviceinfo" on the SPAD.neXt discord. This key will identify the device author and enable author-only functions like e.g. editing the device UI or device configuration database, if the current SPAD.neXt user is the device author.
The authorkey is case-sensitive!
ALLOWLOCAL
The ALLOWLOCAL option controls where SPAD.neXt will search for device configuration files/images etc. before checking the database. Documents refers to the Documents-Directory from SPAD.neXt configuration. Default: "Documents/SPAD.neXt"-Folder of Windows user
SPAD.neXt will search for files/images in the following order
Value = 0 (default)
SPAD.neXt will not search for any local files and will always use
Internal database
Device provided data
Value = 1
Documents/devices/local/<VID>/<PID>/
Internal database
Device provided data
Value = 2
if the current SPAD.neXt user is the author of the device, else it will behave like 0
Documents/devices/<AUTHOR>/<VID>/<PID>/
Documents/devices/local/<VID>/<PID>/
Internal database
Device provided data
if no local configuration exists (or is not allowed), the device sent-configuration will be used always. if a local configuration exists (and is allowed) it will always overwrite any device sent configuration!
VID
The VID (or Vendor ID) defines the author of a device uniquely in a similar manor to USB devices.
The VID cannot be chosen freely, but has to be requested by opening a ticket, to prevent duplicates. The VID is provided and set automatically by SPAD.neXt once it has been assigned.
PID
The PID (or Product ID) defines a device uniquely in a similar manor to USB devices.
The PID can be choosen freely and should be unique per device(type) as it will be also used to find the corresponding device profile within a SPAD.neXt profile.
The PID will be used in SPAD.neXt all over the place (e.g. Variable names), so keep it short and simple. The only allowed characters for the PID are A-Z,0-9 (no spaces, no special chars)
SERIAL
If provided the serial number of the device (unique per device connected!) to identify device variables (ADD Command). If not provided or a duplicate is found, SPAD.neXt will use an internal unique identifier
Device variables
if PID is defined for a device, all its inputs will be available as LOCAL variables within SPAD.neXt as
LOCAL:<VID>_<PID>_<TAG>[suffix]
[suffix] will only be present if more than one identical device is connected
Examples
LOCAL:SHAKEPRINT_ECHO_BUTTON1
LOCAL:C0NNEX_FCU_I_AP1
LOCAL:C0NNEX_FCU_I_AP1_2
(second FCU device)
INIT Examples
Request from SPAD.neXt:
0,INIT,2,0.9.10.0,73993732632;
Reply from device:
0,SPAD,{A8AA15C5-7BB6-4AC6-A558-A88CAFB78729},Altimeter Display,2,1.0;
(No one will be able to locally modify the device configuration)
Request from SPAD.neXt:
0,INIT,2,0.9.10.0,73993732632;
Reply from device:
0,SPAD,{A8AA15C5-7BB6-4AC6-A558-A88CAFB78729},Demo,2,1.0,AUTHOR=a3dhfc4323dca,PID=Echo
The user associated with authorkey a3dhfc4323dca will be able to edit the device configuration. SPAD.neXT will frist search in Documents/SPAD.neXt/devices/a3dhfc4323dca/shakeprint/echo
for local configurations
