Re: [Paparazzi-devel] Log plotter allowable messages?

[Pascal Brisset]

Hi Nicholas,

Messages (conf/messages.xml) are organized into "classes", one for the 
downlink ("telemetry"), one for the uplink ("datalink").

The log plotter handles only the messages from the "telemetry" class and 
reports errors when it encouters messages from the "datalink" class. We 
can use the following trick to fix the problem: duplicate the desired 
"datalink" message description in the "telemetry" class. The plotter 
uses the messages description saved in the .log file. So, edit this 
file, and copy the SETTING entry:
 <message LINK="forwarded" NAME="SETTING" ID="4">
       <field NAME="index" TYPE="uint8"/>
       <field NAME="ac_id" TYPE="uint8"/>
       <field NAME="value" TYPE="float"/>
     </message>
into the the <class NAME="telemetry"> element. You also have to change 
the id because the parser won't accept duplicated ids. For example ID="666"
Load this patched file in the log plotter and you will be able to plot 
the SETTING attributes.
To be able to export these values in CSV format, please update from the 
CVS (since I've just fixed small bug there)
For future logs, you can also patch the conf/messages.xml in the same way

This splitting in classes today appears as a bad idea but ... we have to 
think about it before merging the two classes.

Let me know if it works ...
