j1939
Notes
Sent by the J1939 service to other services which have subscribed to the event. The
path is described generically where:
•
canX is the name of the interface
• pgnYYYYYY is the PGN of interest
• saZZ is the source address of the target CA.
For example, data for PGN 0xF004 from SA 0x00 on interface can0, the path would
be:
j1939.can0.pgn61444.sa0 .
Note that it is possible to exclude the ’saZZ’ argument in order to receive PGN
YYYYYY from any source address. Be aware however that this requires a
corresponding message entry in the configuration file where the
’ignoreSourceAddress’ attribute has been set to ’true’.
Note that all PGN and SA values must be specified in decimal notation (base 10).
Lua Example
Note that the example assumes the application has been configured to call
cb_update_rpm upon receipt of PGN 0xF004.
function cb_update_rpm ( mapargs )
local ev = mapargs .context_event_data
local data = {}
local rpm = ev [" spn190 "] / 8
local rpm_rot = ( rpm / 10000 * 49
data [" tach_exterior.pointer_tach_exterior.rot "] = rpm_rot
gre .set_data( data )
end
