CAN Bus logger

Revision as of 17:56, 28 February 2015 by Brentp (talk | contribs)

The following script will output all CAN bus messages received on CAN channel 1 to the RaceCapture/Pro log window.

After writing the script, you can observe the output in the log monitor window in the RaceCapture app.

However, to gather large amounts of data, we recommend connecting directly to RaceCapture/Pro's serial console using a terminal program like Hyperterminal, RealTerm, minicom or similar.

  • You can view the log by issuing the command 'viewLog' at the serial console.


--500K baud. set your baud rate here.
initCAN(0, 500000) 

setTickRate(30)  --onTick() will be called at 30Hz.

--this function drains all pending CAN messages
--and outputs messages to the log
function outputCAN()
	repeat 
		id, ext, data = rxCAN(0, 100)
		if id ~= nil then
			print(id ..', ')
			for i = 1,#data do
				print(data[i] ..', ')
			end
			println('')
		end
	until id == nil
end
 
function onTick()
	outputCAN()
end
