Hi, I'm using ECU Measurement and Calibration Toolkit with labview 8.0. I use the attached a2l file. When I try to read data from ECU in polling all it's ok in DAQ List Mode I can read nothing. Some one can help me?

If your ECU works with Polling it should works with DAQ lists too. Could you check wether or not your ECU starts sending data if you call the MC DAQ Start command.

If not the ECU has porobably no event channel assigned.

You could check for available Event Channels with MC Get Property "Event Channels". The ECU uses a specific Event Channel internaly to clock the data out.

If the ECU has no event channel assigned you could do that using the MC Set Property "DAQ Event Channel Name" to specify the Channel for your DAQ List.

Additionaly i would like to see a SPY Log file at least, thus i can see hoew your program works. You can run the NI SPY from Start >> Programs>> National Instruments.

Make sure your zip the log file before you post it.

From Get Proprrty "Event Channels" we receive the response "Default" only. When you say use MC Set Property "DAQ Event Channel Name"to specify the Channel for your DAQ List

I have to send the name of the channel? My a2l file is created from a db file, we use ASAP2EDITOR from Vector. and I don't know if during the conversion some info are lost.

I see an other parameter regarding DAQ List single byte o double, I have to set it?

I send you our SPY Log file.

Best Regards

Well it seems it works fine but no messages arrive for your channel selection. Could you check whether or not the ECU transmits the correct frames?

And could you send me a spy log for a working DAQ, you mentioned in your first thread?
