Where does Windriver printf

[omsahmad]

So I know you can setup smartdashboard or DriverStationLCD, but where does Windriver print a line if you just put in the following (as seen in vision example):

	if(scoreCompare(scores[i], false))
	{
		printf("particle: %d  is a High Goal  centerX: %f  centerY: %f \n", i, report->center_mass_x_normalized, report->center_mass_y_normalized);
		printf("Distance: %f \n", computeDistance(thresholdImage, report, false));
	} else if (scoreCompare(scores[i], true)) {
		printf("particle: %d  is a Middle Goal  centerX: %f  centerY: %f \n", i, report->center_mass_x_normalized, report->center_mass_y_normalized);
		printf("Distance: %f \n", computeDistance(thresholdImage, report, true));
	} else {
		printf("particle: %d  is not a goal  centerX: %f  centerY: %f \n", i, report->center_mass_x_normalized, report->center_mass_y_normalized);
	}
	printf("rect: %f  ARinner: %f \n", scores[i].rectangularity, scores[i].aspectRatioInner);
	printf("ARouter: %f  xEdge: %f  yEdge: %f  \n", scores[i].aspectRatioOuter, scores[i].xEdge, scores[i].yEdge);	
}
printf("\n");

DriverStationLCD is pretty limited and I am still figuring stuff in SmartDashboard.

Thanks.

Printf's go to the NetConsole for cRio or to the target console that can be accessed from Windriver. NetConsole is much more convenient as it does not go away when the cRio reboots; if you enabled NetConsole with your cRio imaging tool, I highly recommend the use of NetConsole. You can monitor all printfs from there.

Awesome, thanks

Just be careful of sending a printf() in your while(IsOperatorControl()) loop. The frequency of such a thing is very high and will quickly swamp the network/cRio etc. Often we will use a static int counter or a timer.HasPeriodPassed(500) to only allow a printf to occur a few times per second.

^This. Another good option is to printf() in a separate task that sleeps for 100ms or so every loop - we did this for our DriverStationLCD stuff and any printf()s we needed for debugging last year.
